to recap regarding an earlier question i asked regarding extending
include paths, i have an existing project (call it proj currently
all under a top-level directory also named proj) which can be SVN
checked out anywhere under a user's home directory. so in my case, i
might have my svn working copy under, say,
/home/rpjday/stuff/work/proj/, and all proj-related content under
that.
at the moment, there are some subdirs under proj/ like common and
utils and debug, and all includes or requires throughout the
working copy are currently and awkwardly of the form:
include '../../proj/utils/somescript.php';
in short, every script that needs to include another one somewhere
else in the code structure sadly needs to know its precise relative
location.
my proposal is to get rid of most of that by:
1) having developers set a single env var PROJ_DIR in their login
session, reflecting wherever the heck they checked out their
working copy to, then ...
2) having said developers uniformly extend their directly callable PHP
scripts with something at the very top like:
set_include_path(getenv('PROJ_DIR') . PATH_SEPARATOR . get_include_path());
not only will that let them simplify their command-line callable
scripts to say just:
include 'utils/somescript.php';
also, as i read it, that newly-extended include path percolates down
through all PHP scripts invoked directly or indirectly from this one,
right? so while i could add that set_include_path() to every single
PHP script everywhere in the code base, it's really only necessary to
add it to those PHP scripts that people intend to *invoke* directly --
every other script will pick it up automatically as it's called, is
that correct? (did i phrase that meaningfully?)
that was part one.
the new additional complication is that some of those PHP scripts
will manually construct HTTP POST requests and ship those requests off
to PHP scripts that live under a public_html/ directory, whose
scripts might *also* want to include some of those very same utils/ or
common/ scripts but that modified include path will, of course, not
carry across a POST request, so what's the standard way to similarly
modify the include path of the scripts on the server end?
(unsurprisingly, all those server-side PHP scripts are also part
of the entire SVN checkout just so i can keep everything in the same
place for testing.)
so how can i have those server-side scripts extend their search
path based on, perhaps, the same environment variable?
thoughts?
I think the whole 'set an ENV var in their shell session' idea is overkill.
everything is checked out from svn, the structure of the project is known,
there is no reason not to use relative paths for the includes, there is
no need to tell the scripts where stuff is in this scenario - they can
work it out automatically.
the following might give you an idea for a bit of bootstrap code that's included
by everything:
define('INC_DIR', dirname(__FILE__));
this would allow all other code to use absolute paths and allow you to set
the include_path to ''.
how do the cmdline scripts know which URL to hit ... I would assume that this
URL can change depending on whose checkout it is and the context (dev/prod),
that means there is already a config file or some such - possibly a good place
to stick the include path or define the include dir.
... and now for something 'completey' different:
another trick I've used is to use custom ini settings in conjunction with
get_cfg_var() - each developer/installation would have their own custom ini
file (which you can store in svn too) .. the ini file would be symlinked to
from the dir php is setup to read additional ini files from, the contents of
the ini file would be something like:
[My Cool App]
my_cool_app.public_url = 'http://local.coolapp/';
my_cool_app.inc_dir = '/path/to/cool/app/';
you can then grab these values from anywhere using
get_cfg_var('my_cool_app.inc_dir'),
often I find that additional config stuff is needed per installation - mostly
related
to webserver setup (which sometimes differs somewhat between live and dev
installs -
SSL may not be available/required/wanted and if it is IP addresses need to be
hard coded,
apache may require you to use absolute paths, test systems may require IP
restrictions, etc)
so I setup a dir structure like so:
project/cnf/targets/localhost.jochem/php
project/cnf/targets/localhost.jochem/httpd
project/cnf/targets/localhost.charlie/php
project/cnf/targets/localhost.charlie/httpd

Fortunately, the author gives step-by-step instructions on how to do this on this page: http://blog.maniac.nl/2008/05/28/creating-lto-barcodes/ So I've gotten through all the steps, and have created the barcode_with_samples.ps file, and have it hosted here: http://www.winecarepro.com/kiosk/fast/shell/ Notice how the last few lines contain the shell-script that renders the postscript: #!/bin/bash BASE=”100″; NR=$BASE for hor in 30 220 410 do ver=740 while [ $ver -ge 40 ]; do printf -v FNR “(%06dL3)” $NR echo “$hor $ver moveto $FNR (includetext height=0.55) code39 barcode” let ver=$ver-70 let NR=NR+1 done done I need to somehow create a PHP script that executes this shell script. And after doing some research, it sounds like I need to use the PHP exec command, so I do that with the following file: http://www.winecarepro.com/kiosk/fast/shell/printbarcodes.php Which has the following script: ?php $command=http://www.winecarepro.com/kiosk/fast/shell/barcode_with_sample.ps;; exec($command, $arr); echo $arr; ? And, as you can see, nothing works. I guess firstly, I'd like to know: A) Is this PHP exec call really the way to go with executing this shell script? Is there a better way? It seems to me like it's not really executing. that's what exec() is for. $command need to contain a *local* path to the command in question, currently your trying to pass a url to bash ... which obviously doesn't do much. the shell script in question needs to have the executable bit set in order to run (either that or change to command to run bash with your script as an argument) I'd also suggest putting the shell script outside of your webroot, or at least in a directory that's not accessable from the web. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Event/Exhibition Organizers Management Software
hi gang[tm], I've been STFW for some kind of CRM package specifically geared at event/exhibition organizers. I'm not having any luck, there *seems* to be stuff out there but most of it's geared at single exhibitor/corporate entity event management as opposed to the organization of events where 100s of exhibitors need be approached, sold stand space to and manage - of those that do seem to what I'd like they are a bit vague on their website and don't give any pricing info (as usual price is a big issue :). I've looked at the possibilities of using Salesforce or SugarCRM but neither seem to have plugins/modules aimed at the specific requirements I have. Basically I want something to manage: 1. multiple expos/exhibitions 2. selling standspace 3. manage tickets/ticket campaigns 4. floorplan management/creation/etc 5. speaker/debate-panel management 6. exhibitor pack/documentation management 5. the usual invoicing/lead/crm stuff does anyone know of anything that comes remotely close? rgds, Jochem -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Splitting a string ...
Op 3/15/10 1:54 AM, Ashley M. Kirchner schreef:
I'm not a regexp person (wish I was though), and I'm hoping someone can give
me a hand here. Consider the following strings:
- domain\usern...@example.org
- domain\username
- the same as above but with / instead of \ (hey, it happens)
- usern...@example.org
- username
Essentially I have a sign-up form where folks will be typing in their
username. The problem is, in our organization, when you tell someone to
enter their username, it could end up being any of the above examples
because they're used to a domain log in procedure where in some cases they
type the whole thing, in other cases just the e-mail, or sometimes just the
username.
So what I'd like is a way to capture just the 'username' part, regardless of
what other pieces they put in. In the past I would write a rather
inefficient split() routine and eventually get what I need. With split()
getting deprecated, I figured I may as well start looking into how to do it
properly. There's preg_split(), str_split(), explode() . possibly others.
So, what's the proper way to do this? How can I capture just the part I
need, regardless of how they typed it in?
?php
$inputs = array(
// double slashes just due to escaping in literal strings
domain\\usern...@example.org,
domain\\username,
domain/usern...@example.org,
domain/username,
usern...@example.org,
username,
);
foreach ($inputs as $input) {
// four slashes = two slashes in the actual regexp!
preg_match(#^(?:.*[/])?([...@]*)(?:@.*)?$#, $input, $match);
var_dump($match[1]);
}
?
... just off the top of my head, probably could be done better than this.
I would recommend reverse engineering the given regexp to find out what
it's doing exactly ... painstaking but worth it to go through it char by char,
it might be the start of a glorious regexp career :)

Re: [PHP] I need a fresh look at storing variables in MySQL
Hi Tedd, just a few thoughts that might help ... Op 3/13/10 6:10 PM, tedd schreef: Hi gang: I just completed writing a survey that has approximately 180 questions in it and I need a fresh look at how to store the results so I can use them later. first off - wasn't there a cut'n'dried piece of survey software out there that did the job? don't know off hand what the 'market' currently offers but I'm pretty sure there are a number of candidate php-based wotsits. as such they might be worth looking at just to check out their data models. The survey requires the responder to identify themselves via an authorization script. After which, the responder is permitted to take the survey. Everything works as the client wants so there are no problems there. My question is how to store the results? I have the answers stored in a session variable, like: $_SESSION['answer']['e1'] $_SESSION['answer']['e2'] $_SESSION['answer']['e2a'] $_SESSION['answer']['e2ai'] $_SESSION['answer']['p1'] $_SESSION['answer']['p1a'] $_SESSION['answer']['p1ai'] and so on. As I said, there are around 180 questions/answers. Most of the answers are integers (less than 100), some are text, and some will be null. Each vote will have a unique number (i.e., time) assigned to it as well as a common survey id. what happens when 2 people vote at the same time? My first thought was to simply record the vote as a single record with the answers as a long string (maybe MEDIUMTEXT), such as: 1, 1268501271, e1, 1, e2, 16, e2a, Four score and ..., e2a1, , that would make life very difficult if you wanted to use the Then I thought I might make the data xml, such as: survey_id1/survey_idvote_id1268501271/vote_ide11/e1e216/e2e2aFour score and .../e2ae2ai/e2ai doesn't seem like XML is the answer at all. isn't it Larry Garfield with the sig line that says: Sometime a programmer has a problem and thinks I know I'll use XML, now he has 2 problems. :) That way I can strip text entries for and have absolute control over question separation. Then I thought I could make each question/answer combination have it's own record while using the vote_id to tie the vote together. That way I can use MySQL to do the heavy lifting during the analysis. While each vote creates 180 records, I like this way best. is there only ever going to be one survey of which the questions/structure is now fixed/definitive? if so I'd probably opt for the simple approach of a table with 180 columns purely because that would make for the easiest reporting queries (no self-referencing joins needed to answer the question posed below ... which would be the case if you normalized the data to one row per question+answer+vote[r]) ... although possibly not speediest in terms of SQL performance (you'd have to be careful with creating lots of indexes because that would affect insert performance) basically one table with 180 answer columns and an addition primary [voter?] key, possibly also a survey id if your going to be repeating the survey over time. a more normalized approach would be to define all the questions and their answer types in one table, surveys in another, with answers per qestion in another: survey table: id INT (PK) nameVARCHAR dateTIMESTAMP questions table: id INT (PK) positionINT - order of questions survey_id INT questionVARCHAR/TEXT question_type ENUM? voters table: id INT (PK) nameVARCHAR ?? answers tables: id INT (PK) voter_idINT question_id INT answer ? with the answer values in the answers table you might consider a field for each question_type you define so that you can use a proper data type - this would be somewhat denormalized because you'd only ever use one of those fields per row but it might come in handy. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Is this order something that is specified by PHP and so can be relied upon to stay the same in the future or is it just how it currently works. If it cannot be relied upon to stay this way, I will have to rewrite the multiCall method and API... I think you can probably rely on the call order but given no formal spec for php it's not ironclad - multiCall() will never be called before methodOne() or methodTwo() because the return values of those are needed to pass to multiCall() BUT you can't say for sure whether $client-system will be evaluated before the methodOne() and methodTwo() calls ... looking at it the code doesn't actually require it, in practice it doubt the engine will change so dramatically that the call order would change. but who cares. the code is full of magic, which makes it difficult to understand and maintain ... fix it so that it's explicit about what it's doing so that other developers who read it will grasp the concept without having to dig into your magic methods. this solves the problem of undiscernable magic and possible issues with resolution order in the future as well (which if they happened would be a royal PITA to debug, given the magic methods involved) regards, Auke van Slooten Muze -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I AM A COMPLETE NOVICE WITH LINUX/FREEBSD. It had not been my intention
to
learn the intricacies of Linux. However, I am now neck deep in a mire of
confusion that even MAMP can't seem to sort out for me.
It is purely a guess that I need to start again from a complete clean
setup
(reformatting my hard disk and reinstall OS X again) but that is pretty
much
out of the question.
I guess my question is:
How can I completely uninstall PHP so that I can start again?
Thanks.
I did a:
find / -name 'apachectl' 2. /dev/null
and it came back with:
/usr/sbin/apachectl
/Applications/MAMP/Library/bin/apachectl
Mac OS X has an install of apache by default, the control script for that
is:
/usr/sbin/apachectl
if your installing MAMP (or a custom setup) you'll want to deactivate the
default
installation ... go to System Preferences Sharing then turn off Web Sharing
if you want to deinstall MAMP there should be a deinstaller program in
/Application/MAMP,
once you've run that you can just delete that whole directory. then you can try
to install
again by mounting the MAMP .dmg file and running the installer.
so I do:
cd /Application/MAMP/Library/bin
and then:
./apachectl graceful
and it came back with:
httpd not running, trying to start
(13) permission denied: make_sock: could not bind to address {::]:80
(13 permission denied: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
this is a permissions thing - you need to run the command using sudo (as
explained in
another post)
Does this mean that httpd is not running, and that I need to make some
change to the httpd.conf file? If so, then what changes do I need to make?

When reading get or post I just use $_REQUEST nowadays because I don't have to care how the submitting form is written. This makes my form handling data more portable. a. if your updating/inserting/storing data for the user you should require POST in order to mitigate CSRF et al - not to mention using a nonce in your forms. b. when you use $_REQUEST like you do you assume it's either GET or POST data, but it might be COOKIE data ... which will overwrite what is sent via GET or POST in the $_REQUEST array .. which creates a potential for a denial-of-service attack on the users of a site: imagine an 'id' parameter for displaying articles, then imagine a user was tricked into loading a cookie onto his machine for your domain with the name of 'id' and a value of 1 ... said user would only ever be able to see the article referred to be id=1 if you wrote code that took the 'id' parameter from the $_REQUEST var. ... I advocate not trusting any data *and* being explicit about the input vectors on which any particular piece of data is accepted in a given context. (GET, POST and COOKIE are 3 different vectors) Which becomes a moot point if you use the request_order ini setting to specify the ordering of the overriding of variables in $_REQUEST. which I think is another bit of magic I can do without. besides you don't always have control of the ini file (and you obviously can't change this value during the running of the script as $_REQUEST is already defined) I do see what you're getting at, and yes there are concerns to be had with one global array overriding another if you don't know to look out for such a caveat. The thing is, there are many times where $_REQUEST is just perfect. Imagine a stylesheet picker, that remembers the visitors choice in a cookie. You can utilise $_REQUEST to handle the whole thing very easily, and in a way that makes sense. which would require a request_order of CPG - the opposite of what it normally is, which is a complete WTF for any new developer of the code base, all so you can save a couple of lines of very simple code. I don't think it's worth it. BUT given that you do know what all the ramification are and can control the request_order in your environment then it's true to say that in your case there is no actual problem.

Here's a post from Stephan Esser about it on the PHP-Internals list: http://www.mail-archive.com/intern...@lists.php.net/msg32832.html Stephan heads up the Hardened-PHP project and when it comes to security, I don't know of anyone better. So, if he advises not to use _REQUEST, it's a good idea to follow that advice. -- Richard Heyes Well, he's only saying there that it 'most probably vulnerable' and mentions that cookies can overwrite post and get data. This isn't a problem with $_REQUEST itself but rather an applications' use of it. So what if someone crafts a cookie to send a bad value. If someone has the gen to do that, then they are going to know how to send get and post values as well. Only decent sanitisation will be able to protect against this. If the order of override variables in $_REQUEST is such an issue too, use the request_order ini setting to specify the order you'd prefer. I've never had any issues with using $_REQUEST, but found a lot of advantages to using it, as I often use a mix of data sources in the same app. and that is exactly Essers point. you use $_REQUEST and assume the data came from either GET or POST ... I'd hazard a guess your apps never expect such 'mixed' data to be coming via COOKIE ... so your app will work as 'advertised' but if some one happens to slip a cookie onto someone else machine whose name matches some rather important GET/POST input then it's that user who potentially has just suffered a denial of service - and you'll get the blame for the fact things don't work and you'll probably never be able to work out that it's a rogue cookie on the client putting a spanner in the works. (imagine you have an 'id' parameter and I managed to set a cookie on your users' machine called 'id' with a value of 1 ... have fun with that) you should be as strict with exceptable input vectors as you are with sanitisation of the actual input. use of $_REQUEST is rather lazy - if you want to except either POST or GET for a given input write a simple wrapper function for that specific requirement - this will also save you from unforeseen problems related to incorrect or changed values for the request_order ini setting.

The 'correct' way of doing this is to use a 'sequence' which is

Firebird(Interbase) has had 'generators' since the early days (20+

ADOdb emulates sequences in MySQL by creating a separate table for the
insert value, so you can get the next value and work with it, without
any worries. The only 'problem' is in situations were an insert is
rolled back, a number is lost, but that is ACTUALLY the correct result,
since there is no way of knowing that a previous insert WILL commit when
several people are adding records in parallel.
this is all true and correct ...

Hi
I would like to learn more correct way from both of you.
May I ask what is a sequences ?
it an RDBMS feature that offers a race-condition free method of
retrieving a new unique identifier for a record you wish to enter,
the firebird RDBMS that Lester mentions refers to this as 'generators'.

What I am trying to achieve is to have a php script run once a minute
and do a few tasks. There are some constraints:
- Users usually install the php application on their local machines, be
it Linux, Windows, or Macintosh.
- The application is defined as needing zero-configuration, i.e. it runs
out of the box.
much too vague. no mention of a webserver ... zero-config and needing to
install
are somewhat mutually exclusive.
I still have the feeling you're using the wrong tool for the job somehow,
I may be wrong or drunk or both ;)
Well, on the web server, this usually would be Apache, though one user
indicated he would use some light httpd instead. Then, of course, yes,
installation is not zero-config, but what I mean is that after
installation no further configuration steps would be needed, e.g. if the
user unpacks a tarball in the web root, it should run straightaway, or
if he does 'apt-get install pacakge', no further configuration would
be needed. I thought therefore that using visitors page requests was a
clever way of initiating starting a php script. At the moment I've got
the following code:
if you're doing all this already in order to facilitate a multi-platform
install ... why not go the extra yard and have the install process setup
a cronjob (or scheduled task, launchd entry, etc, depending on platform)?
$crontable = Database_Cron::getInstance ();
if ($crontable-getFlag ()) die;
$crontable-setFlag ();
ignore_user_abort(true);
set_time_limit(0);
while(1)
{
$log = Database_Logs::getInstance();
$log-log (Minutely maintenance routine started);
.. do some maintenance ...
$log-log (Minutely maintenance routine finished);
sleep(60);
}
of itself this seems like reasonable code, people argue about
the finer details but you seem to be writing clean and tidy stuff.
as such I still don't think this kind of thing belongs in a webserver
process.
I have recently been using daemontools (*nix/bsd compatible daemon management
tools ... also used to manage qmail processes) to actually keep a
long running / perpetual script running ... it's a very robust bit of
kit which takes care of running just one instance of whatever
and restarting it if it happens to die ... very nice, very simple, not
available on Windows (AFAIK) ... and helps to keep this kind
of management logic out of the actual php app.
This uses the mechanism of a sql table in memory, which seems fine for
the moment, since it is volatile and would disappear if the user
restarts his laptop (or if the Amazon cloud reboots ;) - thus next time
the user visits any page, this script would be restarted and do the
maintenance till the user shuts down, and so on. I still have to look
into the other mechanisms of creating a volatile flag.
I think therefore, with my limited experience of PHP, that the above
does well, though improvements are welcome.
I'd think your php is an issue - little bit I've seen suggests you
code diligently, it's merely the vehicle your using to have the script run
perpetually that irks me.
About scripts running forever, I don't see a problem here since most of
the time it sleeps anyway, and when I look in my Ubuntu 9.10 laptop,
doing ps ax gives 194 live processes already, so what does the one
single extra sleeping process matter?
in practice not much on a personal machine - nonetheless it's wasteful
and technically a webserver is unneeded and creates another layer of
complexity and overhead. it does seem rather brittle in terms of how you
have it set up though.
realise that your Ubuntu laptop is *probably* alot more stable, robust when
running a never-ending Apache child [worker] process with mod_php loaded and
executing ... I'd be quite confident that it would be stable and such on my
Mac as well ... but a Windows machine, I wouldn't trust that to do it ...
and keep running reliably (not from the script or the user POV)
it's possible that it's the best you can do given the pratical circumstances
of the users/maintainers of the installations ... but I hazard to say
you 'wrapper' for you perpetual/reaccuring script *might* be a sub-optimal

In your case, the variable would be something like this:
$query=INSERT INTO upload_history (v_id,hour,visits,date) VALUES
({$v_id}, {$hour}, {$visits}, '{$date}');
actually IIRC the engine compiles that to OpCodes that equate to:
$query = 'INSERT INTO upload_history (v_id,hour,visits,date) VALUES ('.$v_id.',
'.$hour.', '.$visits.', '\''.{$date}.'\')';
Much more readable and maintainable IMO.
No need for the trailing semicolon in SQL that uses an API like you

Backticks around column names are not required and IMO again they just
make the code hard to read. Just because phpMyAdmin uses them, doesn't
mean we all need to.

I don't think that you'll get much else than Blender or PHP-GTK - so from that perspective I'd hazard a guess that your not going to be finding anything that will allow you use php for desktop development in the way you require. come to think of it M$ has been doing something to shoehorn PHP into the .NET env ... I have no idea whether this would be anything that could bare fruit for you, you'd have to google. as an alternative you might consider Adobe Flex Builder - you get WYSIWYG-ness, you can leverage javascript skills (by way of ActionScript) and it's runs on the AIR platform - so it's nice and desktoppy but with the added bonus of being cross-platform. just a thought.

Like I said, I typically find I can custom write one with better results. I found xCart, for example, to contain some of the worst code I had ever seen and it turned me off to third party carts. I find the only time a custom solution is suitable is when there is a large budget and very specific requirements, which usually translates into atleast: 1. specialized discounting mechanisms 2. tight integration with a 'big' backend system (e.g. SAP, Siebel, etc) 3. custom data-related workflows I just spent some time looking at XCart for someone - seeing the frontend I figured the requested changes would be a piece fo cake, the reality is that making those changes was practically impossible and definitely not ecomonically viable. the XCart code is complete pants. I also took a dive into the Magento codebase, a quick perusal shows a well defined structure, tidy code, well commented, modular. looks very good really - learning curve is a bit steep but that's down to the fact that it's a very complete and sophicated package ... additionally there is a big, well organized community behind it ...

what does it matter that it runs slowly, run it once and be done with it?

Re: [PHP] Migrating legacy code - changing session name

Hello List
A client has asked me to migrate a few scripts that have been running
merrily under PHP4 to PHP5.2. Part of these scripts have integration
with PHPMyAdmin
using the single sign-on and so they make use of the following code :
session_write_close();
session_name(blah);
session_start();
Now, assuming that prior to session_write_close(), I have a session
that (amongst other elements) contains the following:
$_SESSION['a'] = (an instance of Object A)
$_SESSION['b'] = (an instance of Object B)
$_SESSION['c'] = (an instance of Object C)
After session_start(), I have the following :
$_SESSION['a'] = (an instance of Object C)
$_SESSION['b'] = (an instance of Object C)
$_SESSION['c'] = (an instance of Object C)
sounds to me like the objects are a stored in a variable, each time
the same variable that the var in question is assigned by reference
(this is done in php4 code quite a bit so that objects that are
passed around are not copied - which makes them useless in many instances)
the following code mkight help you to understand what it is (that I think)
is happening:
// php4 compatible class
class Foo { var $s; function Foo($s) { $this-s = $s; } };
$store = array();
$var = new Foo(A);
$store[A] = $var;
$var = new Foo(B);
$store[B] = $var;
$var = new Foo(C);
$store[C] = $var;
var_dump($store);
This does not consistently happen, only under particular circumstances
(it seems to be a certain set of elements in $_SESSION triggers it).
For instance, if I unset $_SESSION['b'] * prior* to doing
session_write_close() - the behaviour stops, and the elements are
retained. Has anybody seen this before?
Vital Stats:
PHP5.2
Apache1.3
FastCGI
Sessions are stored using PHP5's default session handling.

The only (untried) solution I can think of is to replace each carriage

pre with a div class='monospace' or some such hackery before running
loadXML() on it. But I would rather not do that.

How about showing a little of the insert code. ie: how you are
gathering the
data, how you are preping the data, and the actual insert statement.
You're also forgetting one of the most important elements of this. If
you're displaying the characters on a web page, chances are that you
need to add a corresponding meta tag to inform the browser that the
content is utf-8
meta http-equiv=content-type content=text/html; charset=UTF-8/
Otherwise the browser will attempt to guess from the first few
characters of output, and because of the large headers in some websites,
will guess completely wrong.
that was point 4. in my original post, I'd also say that the META tag is a bit
lame on it's own ... better off actually setting the proper content encoding
HTTP header
(and using the META tag as well to cover for dumb ass browsers)

You can't use getConstant('KILL_SWITCH_NOTES') as False is returned

How about showing a little of the insert code. ie: how you are
gathering the

Re: [PHP] integrating shipping with shopping cart site - OT
Op 1/18/10 10:47 AM, Angelo Zanetti schreef: Hi all, We are about to start a new project. Custom written shopping cart - quite simple actually. However we have a concern when it comes to calculating the shipping cost for an order. For each product we can determine the base cost based on weight, therefore we can determine the total weight of an order. However we are struggling to determine how to calculate the shipping based on where the delivery is going. In terms of DB and PHP would the best way to calculate it be done by having a list of countries to ship to and a rate for each? Then you can apply the rate to the current order (calculate according to the order weight). Problems arise when shipping to different parts of a country EG: New York vs California (quite far apart). Perhaps we should have a list of cities but that could be massive? I know there is a PHP class / system that integrates with UPS but I don't think the client is going to use UPS. Perhaps you can tell me how you have handled this issue in the past. Apologies if it is slightly off topic but it does still relate to PHP indirectly. I'd start with defining shippingcost 'sets', each defining a number of costs by weight bands, some 'table defs': set: - id name set_bands: -- set_id upper_weightcost then it would be a case of linking (many-to-many relation) 'regions' to sets, if you approach this with a tree of regions you can effectively set values at a continent, country, state/province level ... as such you would only need to relate a 'shippingcostset' to a state if the shippingcosts are different to the given country's shippingcosts. world - north america - california - south america - europe - france - UK then your left with the problem of determining the smallest defined region a given address physically falls into .. using geo-spatial magic in the DB would be one way to do it. this is a hard problem (unless, maybe, the client is willing to sacrifice precision and instead using highly averaged shipping cost definitions to cover the real differences in costs - i.e. a fixed fee for all of europe, whereby such fee is just above the average real cost the client pays for shipping). my guess would be that building such a thing is hard, and would take lots of time ... best bet is to hook into the webservice of whatever shipping company the client intends to use ... even if you have to build your end of the webservice from scratch it will be many factors less hard that building a user-manageable, shipping cost algorythm. - sorry it's all a bit vague, I'm very tired :) my eyes are starting to bleed.

I have a content subdirectory where I store all the pages with files such as

As I said, this has been working fine up until now, if I use the url

Re: [PHP] cookies and carts
Allen McCabe schreef:
I have a shopping cart type system set up which keeps track of the cart
contents using a SESSION variable, where $_SESSION['cart'][$item_id'] is
equal to the quantity, so the name/value pair is all the information I need.
But sessions are unreliable on the free server I am currently using for this
website (not my choice), so I had start using cookies because users were
being sporadically logged out, sometimes just on a page refresh.
I want to find a way to set a cookie to remember the cart items as well, and
I thought setting a cookie for each item/quantity pair was the way to go
until I started trying to figure out how to unset all those cookies if the
user empties their cart.
Is there any way to set cookies with an array for the name? Intead of
$_COOKIE['item_number'] have $_COOKIE['cart']['item_number'] like I have the
SESSION?
1. use one cookie for this (and other data)
2. DO NOT USE serialize()/unserialize() to pack/extract the data
using unserialize() opens you up to alsorts of potential hacks (IMHO), keep the
data
structure simple and revalidate it's entire contents everytime you read it in
(assuming your article ids are INTs, all the data should be [valid] INTs -
anything
else and the cookie should be deleted).
here is some code to play with: (written directly in my email client, no
garantees is
parses or works as is)
?php
function buildCookieCartStr(array $data)
{
$out = array();
foreach ($data as $artId = $quant)
$out[] = $artId.':'.$quant;
return join('|', $out);
}
function parseCookieCartStr($s)
{
$data = array();
$items = explode('|', $s);
if (!is_array($items))
return killCookieCart();
if (count($items)) foreach ($items as $item) {
$item = explode(':', $item);
if (is_array($item) || count($item) !== 2)
return killCookieCart();
foreach ($item as $v)
if (!$v || ($v != (int)$v))
return killCookieCart();
if (!isValidArtId($item[0]) || ($item[1] 1)
return killCookieCart();
if (isset($data[ $item[0] ]))
return killCookieCart();
$data[ $item[0] ] = $item[1];
}
return $data;
}
function killCookieCart()
{
// TODO: delete cookie
}
function isValidArtId($id)
{
return true; // TODO: valid article id
}
?
you can secure your code further by using the filter extension in combination
with a regexp filter in order to retrieve the cookie data from the request,
here's a regexp that matches only non empty strings with digit, colon and pipe
chars:
#^[\d:\|]+$#

there is, your control-Z is not a Z at all, and it's only printed as ^Z

I have tried a ton of different things to try and fix this. Tried
/\c.|[^0-9A-Z]/, and many variations of \c and the [^0-9A-Z], to no
avail. I also tried using both preg_replace() as well as ereg_replace().

If you know what you want, then put those objectives in a list of requirements. You don't have to be a programmer to know what you want, but you must be able to effectively communicate those ideas to the programmer so that they can: 1) understand what you want; 2) and can tell you if it's possible and what cost and time. I always tell my clients that If they can describe it, then I can do it -- however, some things can take more money/time than they an afford.

Here's another thing you must realize -- as the client you can choose: Quality; Time; Or Cost as your main concerns, but only two of them -- not all three. For example, if you want it done quick with high quality, then it's going to cost you. If you want high quality and low cost, then it's going to take a while. And if you want it done quick with low cost, then expect low quality -- and at that point, a respectable programmer would normally pass on the project -- professionals don't turn out crap. speak for yourself ;-) seriously though, good points. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] dynamicaly append method to class - workaround for aggregate_methods()
Karel Kozlik schreef:
Hello,
thanks for the hint. It looks nice. Where could I learn more about
$class::$method() syntax? I was not successfull when searching in php
manual.
er, dunno - I picked it up on the internals mailing list I think, you
might wnat to search that.
Btw. is it an intended behaviour that $class::$method() works in this
way? I mean that I would pressume that method is called in static
context and the $this should not be avaiable in the method than. So I
affraid a bit that the behaviour will be changed in the (near) future.
this is intentional, it isn't going to change ... yes it is weird, we
had a thread about this issue before not long ago on this list where someone
thought it was a bug (I concurred until I was corrected).
But there still remains two issues:
1. How to pass arguments to method? The number of arguments is different
for each method. So is the only way to construct a string containing the
arguments and use eval()? Or is there an another way?
then use call_user_func() and/or call_user_func_array() inside __call(),
although given the seemingly 'broken' (mho) design and infinite variations that
are
possible in terms of method argument invocation you might consider
tackling the whole system from a wider perspective (probably not what you want
to
hear I guess)
also see: http://bugs.php.net/bug.php?id=40694
basically the by-ref issue is not, seemingly, really solvable - I'd say using
by-ref
in most cases is unwarranted anyway ... but, you may be able to work round it
by using
a static variable inconjunction with a, second, retrieval method in the
decorating classes that overcome the requirement for by-ref ... if that makes
sense.
looks like you have your work cut out for you!
2. Arguments sometimes need to be passed by reference. It seems that
__call() does not support passing arguments by reference :(. So I have
not idea how workaround it.

function common_funct_foo(){

class DataLayer_get_items{
function get_items(){
$this-common_funct_foo();
return something;
}
}
And they could also call other dynamicaly added methods:
class DataLayer_update_attr{

All the stuff is used e.g. in this way:

$data-add_method('get_items');
$data-add_method('update_attr');

Now the question is whether is it possible to somehow replace

take a look at interfaces, with the intention that you normalize the method

AHA, I see.
There's a PHP configuration that cookies are available on HTTP side
only, that should provide the desired security in this case, right?
only if you assume there is no bug in the browser allowing the attacker to
circumvent that (the http cookie exists by definition on the client), and
only if you assume stealing cookies is the only malign action an attacker
might wish to take.

Well nobody forces you to upgrade. But it would be wise. Now the bug in curl is still fresh in your mind. But if you forget and decide to enable it later.

If that's a direct copy/paste from your actual code, there is an extra

try if trim() gives you any different result:
if (empty(trim($_POST['PASSWORD'])))

definitely gives a different result.

Re: [PHP] non static function called as static one
Olivier Doucet schreef:
Hello everyone,
I'm wondering if the following behaviour is a bug or a feature. The case is
quite complex, so let me explain my point of view.
here is the source :
?php
class MyTest {
public function myfunc() {
echo get_class($this);
}
}
class MySecondTest {
public function test() {
MyTest::myfunc();
}
}
$test = new MySecondTest();
$test-test(); //output: MySecondTest
?
Let me explain :
In this case, $this is MySecondTest, which is relevant as it is the last
object context. But to my mind, this code should not work like this.
Imagine you are the developer of function MyTest. You want your code to
interact with other classes and being bugproof. 'MyTest' class here seems
OK: $this is expected to be 'MyTest' because function myfunc() is expected
to be called in a non-static context.
Programmer of the second function created this bug and this unattended
behaviour.
Maybe this can be done :
1/ Forbid calling the function in static context (How can I test this ?
$this is not NULL there !).
actually I thought that the engine died in situations like this. I don't
see any change to the behaviour in 5.3 either.
2/ (or/and) Raise a warning or an error if a non static function is called
as a static one
develop with error_reporting set to E_ALL | E_STRICT, then you'll get a big fat
warning about it
3/ Create two functions with the same name, one static and the other one
not. Unfortunately, this can't be done (yet ?).
will never happen (where 'never' = 'very very very long time, at the very least'
What do you think ? What's your point of view on this ? I want your
feedbacks before opening a bug ticket, as it is not strictly a bug...
I think it's inconsistent implementation. I would classify it as a bug,
especially given the general trend to strict/pure OO concepts in php.
there maybe underlying technical issue with the engine that means
this can't be easily fixed.
I would suggest asking on internals to see what their opinion is.
the pragmatic solution is to not call non-static functions using
static syntax.

PJ schreef:
Seems it should be simple, but how does one extract values from an array

1. if $categoriesIN comes from a POST, use $_POST['categoriesIN'] instead.
better yet use the filter extension (part of the core) to retrieve the input.
2. validate santize your input (the reason to use the filter extension)
3. WHY do you want to extract the values and assign them to vars?
since you don't know the number of entries there is no point in creating
a stack of variables of which you have no idea what they are even called
or how many there are. instead loop the array or use an index into the
array to find the data your looking for. you don't have to create a
specific variable to use a piece of data the given element of an array
is just as valid.
4. there is the extract() function ... use at your own risk.
5. do something like this:
foreach ($array as $key = $val)
$$key = $val;
.. again use at your own risk.
echo $categorybr;
}
or
if(!empty($_POST['categoriesIN'])){
foreach( $_POST['categoriesIN'] as $key = $value) {
echo value = $valuebr;
}
both show the values entered in the form but do not create a variable.
Since the number of entries will vary, I cannot assign a number of
variable names before knowing how many entries there may be.

seems like you've done your best to make it sound as confusing as possible,
this happens sometimes when you no longer see the wood for the trees :-)
What I have is a query lets say :
select country,name,population from USERS where id= 'some_id' ;
'USERS' seems like an odd namew for the table in question.
Now I want to assign the result to one set (The above example might have 3+

:
[id][country][name] = population .. or to be exact if I echo the
value for each id and country and name to get the population value
Like :
Array {
[id] array {
[country] array {
[0] = USA
}
[name] array {
[0] = test
}
}
I'm not grokking that array structure much.
I dont know something like that, maybe Im over comlicating the question now
even, the main thing is wondered was in the first place was with a standard
query and variable assign, from the query like:
select country,name,population from USERS where id= 'some_id' ;
normally you would just assign each field to one variable. like
$country = result[country]
$name = result[name]
sidenote: I never see the point of assign the vars like that anyhow, why not
just use
$result['name'] and do away with the exytra $name var?
But now I want all 3 fields as one variable (which would be an array) ..but
how ?
why? I'd guess it's because you want to do a 'look-up' of the data, that
would suggest you don't want to be extracting the data on a row by row basis,
but rather grab all the data and parse it into a format you can use for

self::$data['countries'][$c] = 0;
self::$data['countries'][$c] +=
$row['population'];
}
}
}
}
you would use this class something like:
echo Population::byId(1), \n;
echo Population::byPlaceName(Texas), \n;
echo Population::byCountryName(USA), \n;
var_dump(Population::getAll(names));
var_dump(Population::getAll());
I hope I have not totally confused the question now.
if you didn't then I probably have. enjoy.
Thanks in advance

Hehe,
I don't agree with either :-)
But I am still searching for some solution, and when (and if) I find it
I will be happy to share with you (btw, obviously nobody shared

no, but did the comments I made about var vars and vars included via other
[optional files] register?
also you might consider something low key as a starting point, here's
a handy little oneliner for the [bash] shell:
find . -name \*.php \! -exec php -d error_reporting=4095 -d display_errors=1 -l

Re: [PHP] DOM recursion
Joanne Lane schreef:
I am trying to create a class that recursively iterates over an array an
creates XML tree to reflect a multidimensional array.
I am not really a PHP coder, but am trying my hand.
I've seen 'real coders' write stuff thats leagues worse.
This is what I have so far.
http://pastie.org/private/w75vyq9ub09p0uawteyieq
I have tried a few methods, but I keep failing.
Currently, all elements are appended to the root node.
line 44 is the issue (kind of), you're always adding to the root node,
regardless of 'level'
the createNode func needs a little extra something, I played with it for a few
minutes
and come up with this .. probably not exactly what you need but it might offer
a little inspiration (not I also changed the form of the input array a little):
?php
class array2xml extends DomDocument
{
private $xpath;
private $root;
public function __construct($arr, $root='root')
{
parent::__construct();
/*** set the encoding ***/
$this-encoding = ISO-8859-1;
/*** format the output ***/
$this-formatOutput = true;
/*** create the root element ***/
$this-root = $this-appendChild($this-createElement( $root ));
$this-xpath = new DomXPath($this);
}
/*
* creates the XML representation of the array
*
* @accesspublic
* @paramarrayThe array to convert
*/
public function createNode( $arr, $node = null)
{
if (is_null($node))
$node = $this-root;
foreach($arr as $element = $value) {
if (is_numeric($element)) {
if (is_array($value))
self::createNode($value, $node);
} else {
$child = $this-createElement($element, (is_array($value) ?
null : $value));
$node-appendChild($child);
if (is_array($value))
self::createNode($value, $child);
}
}
}
/*
* Return the generated XML as a string
*
* @accesspublic
* @returnstring
*
*/
public function __toString()
{
return $this-saveXML();
}
/*
* array2xml::query() - perform an XPath query on the XML representation of
the array
* @param str $query - query to perform
* @return mixed
*/
public function query($query)
{
return $this-xpath-evaluate($query);
}
}
$array = array('employees'= array('employee' = array(
array(
'name'='bill smith',
'address'=
array('number'=1, 'street'='funny'),
'age'=25),
array(
'name'='tom jones',
'address'=
array('number'=12, 'street'='bunny'),
'age'=88),
array(
'name'='dudley doright',
'address'=
array('number'=88, 'street'='munny'),
'age'=23),
array(
'name'='nellie melba',
'address'=
array('number'=83, 'street'='sunny'),
'age'=83)))
);
try {
$xml = new array2xml('root');
$xml-createNode( $array );
echo $xml;
} catch (Exception $e) {
var_dump($e);
}
How can I fix this so that the XML tree, correctly reflects the array
tree.
TIA

Re: [PHP] PHP script lag (5 secs) when declaring mime type.
Jsbeginner schreef:
Hello,
I don't know for sure is this problem is only related to PHP so I hope
I've posted in the right list.
My problem is that with certain headers my script takes about 5 seconds
before sending the page, no matter how small the file I try to load...
My server :
Centos
Apache 2.2
PHP 5.2.9
Here's my code :
?php
header('Content-Type: application/x-javascript');
header('Content-Length: '.filesize('test.js'));
readfile('test.js');
?
test.js is only a few lines long, and if I remove the header content
type the file loads instantaniously do it's not a problem with readfile.
I thought about zlib gzip taking maybe a long time to load but I've
changed the compression level from 6 to 1 and the file still has a the
same lag.
My server responds very fast for eveything else except this script. Do
you have an idea what might be causing this lag ?
something to do with apache, usually we we see this it's something to do with
DNS
lookups ... unlikely in your case.
I figure it's something to do with apaches' content negotiation, possibly it
looks up
your content-type for some reason but ends up not recognizing it (and tries
alsort of
stuff before giving up and just sending the output)
http://httpd.apache.org/docs/2.0/content-negotiation.html
question is do you really need application/x-javascript?
won't text/javascript do just fine? or does that have the same problem?
... actually does the problem occur with any value for 'Content-Type'?
Thanks in advance :)

So, question is NOT whether php is interpreted or compiled, or is there a compiler, question is rather is that compiler useful for my problem.Best regards 1. you should *try* to standardize everyone on a single IDE/tool-chain 2. a decent IDE will give warnings about vars that are [seemingly] uninitialized or used only once. 3. a compiler can't cover all situations (variable variables, vars defined in optional includes, etc) 4. there is no silver bullet. 5. try to compartmentalize code so that the scope of a var doesn't exceed the number of lines you can view in a single screen (makes it easier to spot typos, etc) 6. I am not a number. I completely agree with Hans, as PHP cant be directly compared to that of java's behaviour. Hans is the OP, the one you thought got it all wrong., you're actually agree with me ... which is as natural as it is inevitable ;-) All of your team should be using a single IDE or at least good IDEs like Zend Studio, Eclipse PDT, NetBeans PDT while Netbeans is currently the best. PHP is more of a loosely typed language you cant really rely on compile time or something like that to be able to detect old typo bugs etc. The other way is writing a separate engine to detect those sorts of bugs, but using IDE and checking them manually can only ensure the perfectness. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
