Re: [PHP] general organization question
It'll make a small project seem huge in no time flat, but that's the price you pay for 'organization' and stuff. But frameworks can also make a huge project seem medium which is the advantage of organization. Also, it's quite often the case that a small project grows and slowly becomes a big project. At which time the payoff can be realized :) Da, this is true. It's what separates the good developer from the merely mediocre: experience teaches how to code a small project quickly, but keep it organized and flexible to adapt to the inevitable growth and refactoring. A framework that reflects this flexibility is a help, one that doesn't is a hindrance. ------ michal migurski- contact info, blog, and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Best practise for resolving potential conflicts when editing db content?
I'm not sure table locking is the answer. I'm not talking about concurrency in the sense of 'simultaneous' updates and selects, but in the sense of an 'open record edit session' that predictably will overwrite the value of a record that may have been changed, after the edit session began, but before the edit session is committed. Martin Fowler's book, "Patterns of Enterprise Application Architecture" (dull name, I know) has an excellent chapter which describes various kinds of locks. The main applicable distinction in your case is whether you want your lock to be Optimistic or Pessimistic, in other words - do you expect that such conflicts will happen frequently, or no? If you expect conflicts often, make your lock pessimistic: when user A opens ups a record to edit, a flag gets set on the server which prevents user B from modifying the same record. This form of locking is also good when the change process is coarse, and losing edits would be a major inconvenience. In the case of editing a wiki page, you don't want user B to spend 20 minutes modifying a page, only to be told that there's a conflict and they should try again later, wasting all that work. You want them to know ahead of time. Your "beingedited" field in the DB is an example of a pessimistic lock. If you don't expect conflicts often, or the cost of a conflict is low, make your lock optimistic: when user A and user B both have a record open, the first one to commit wins, and the second one gets an error message. This is an easy one to implement if you version your changes in some way, perhaps by indicating which version a user started with at commit time. CVS works this way, as does my wiki software of choice, Tavi Wiki. For these applications, the cost of a conflict is high (which would indicate that a pessimistic lock might be better), but there is a clean method provided to resolve them when they come up. -- michal migurski- contact info, blog, and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I think it's only a problem if you're storing truly stupendous amounts of text, and then it's just a storage problem - drives are cheap. If anything, storing the changes only would probably be a bigger processor load, since viewing any one page would mean having to reconstruct the content from all previous versions. This way, the overhead of a diff is only incurred when you want to view changes to a file between two given versions. I think the rationale behind CVS storing just diffs is that it has branches and merges, while wiki text generally does not. Also (conjecture) it may be a historical legacy of RCS, from a time when storage was not quite so cheap. ----- michal migurski- contact info and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Your bug is being caused by short months. If you ask mktime() to give

december. You can see more clearly what's going on if you shorten your
code, like so:
for($i=0;$i < 12;$i++) {
echo "{$i}: ";
echo date("d m Y",mktime(0, 0, 0,date("m")+$i , date("d"), date("Y")));
echo '';
}
It's a good thing you're trying this today; if you had tried it a few
days ago, you wouldn't have had any idea that your method wasn't
working.

There are some bugs in IE5 which require the use of a few extra cache
headers, for good measure. For data which I don't want cached, I use this:
header('Cache-Control: no-cache, must-revalidate'); // HTTP/1.1
header('Cache-Control: post-check=0, pre-check=0'); // damnable IE5
header('Expires: Wed, 16 Nov 1977 10:00:00 CET'); // date in past
header('Last-Modified: '.date('r'));// right -now-
header('Pragma: no-cache'); // HTTP/1.0

If you don't want to use the shell, you can check the $_SERVER['PATH']
environment variable. On my (linux) system it looks like
"sbin:/usr/sbin:/bin:/usr/bin:/usr/X11R6/bin", so you could explode() that
on ':' and then cycle through the files in each directory using readdir(),
checking each with is_executable().
You could also just check the output of your exec() call - it should be
the full path of the executable you're looking for. An empty return would
imply that there isn't a matching executable. I think which always returns
just the first match, since it's meant to show what would get called if
you were to use that command.
Personally I love using exec() to make php behave like bash at times, but
posts on this list from pparently knowledgeable people occasionally imply
that it's not the best/fastest/most stable method to use, so I try not to.

$things[7] is actually an associative array containing the seventh result

A slightly more general question: are there any PHP development environments that let you do something like a core dump, to see what kind of memory usage or variable allocation you have going on?

No, you can use them right away - they are stored server-side, so you don't need to wait for a request/response loop before reading them: session_start(); $_SESSION['foo'] = 'bar'; echo $_SESSION['foo']; // 'foo' is available immediately No need to perform any special declarations. It's cookies that need to wait for a subsequent request to be available via getcookie(). Careful with your session variable naming - you may want to implement a primitive namespace, by using named arrays in $_SESSION, such as $_SESSION['auth']['username'] or $_SESSION['prefs']['boxers_or_briefs']. -mike. - michal migurski- contact info and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

A few options: use multiple cookies, e.g. setcookie('cookie_a'),
setcookie('cookie_b'), etc. Jordi's suggestion is also good, though I
would suggest using serialize() to make a single string out of your
values, like this: serialize(array('name1' => 'value', 'name2' =>
'value'). Or, use PHP's built-in session support. The cookie stores a
unique ID, whie the actual values are stored on the server.

Anyone got any ideas on > how to fix, or tell me Im barking up the wrong tree... After the first call to substr_replace, you swap in some replacement text that contains an '%s'. Subsequent calls to substr_replace use your replacement text as the key, because it's no longer possible to uniquely determine what was part of the original string, and what was swapped in. Recommendation: don't use preg_match. You can try using preg_replace with arrays as arguments, but you may come closer to sprintf's correct behavior if you instead consume the pattern string ($sql) character by character, generating an output string made up of characters from the pattern string, and elements array_shifted off of $data as you encounter placeholders. Don't forget to add a placeholder that allows you to use '%' in that string -- sprintf uses '%%'. Much easier recommendation: use provided sprintf, but parse out any unwanted placeholders first, using preg_replace. ----- michal migurski- contact info and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Where would you store the passphrase to the key? This is a losing battle - at some point, anonymous requests from the outside world are going to have to result in some kind of access to the database. I think you'd be better off accepting the inherent security tradeoffs as a known variable, and working from there: write your code so it's not vulnerable to SQL injection or other attacks, limit the access permissions of the database user, put the file containing the password someplace where the webserver won't divulge its content (apache config or .htaccess is a personal favorite of mine), and (important!) back up your DB regularly so that you can recover from attacks cleanly. -mike. --------- michal migurski- contact info and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Perhaps convert is not in your path?
Also, I'm not sure that the -geometry argument is going to behave how you
expect - typically, geometry is expressed as "WxH", not "W x H", in
command-line arguments to imagemagick. In the former case, you will set
the size of your output image to W width and H height. In the latter case,
I believe that the 'x H' is ignored, and you implicitly set the size of
your output image to W width and W height. Big difference for any aspect
ratio besides 1:1.

Re: [PHP] file locking question

If you want to ensure that the file is not changed by other scripts while
you're reading from it, yes. Note that this is advisory only - writer
scripts will only respect the lock if they request a write lock. See
manual for details.
> if so, can I just use something like

flock() takes a file handle as an argument, not an array of strings:
$fh = fopen("/path/file.ext", 'r');
flock($fh, LOCK_SH);
// read from file here
flock($fh, LOCK_UN);
fclose($fh);
See example 1 in the manual page for flock for more info.

The progress bar goes by too quickly for me to tell, but perhaps they are using a slow-loading resource someplace on the page? E.g., an image whose content-length is 64, whose 64th byte does not get sent by the server until the query is complete.

It will only make a difference if the HTTP response from the server is
different somehow -- contains junk, wrong headers, that sort of thing. The
only way to reliably diagnose such problems is to figure out a way to view
the entire HTTP response, headers and all. I use curl for this, but you
might not have access to a command line. The mozilla view-headers thing I
mentioned - I've never actually used it {{embarrassed shrug}} so I can't
help you find it, but there are many ways of achieving the same end.

Try fetching it with cUrl, or using Mozilla's view-headers feature. Make sure that the PHP is in fact being parsed, and that the Content-Type header is correct.

There are no "xml tags" as such; XML defines a grammar but not a vocabulary. The actual tags used depend on the specific application in question, e.g. XHTML defines one set of tags, SOAP another. You can define your own, if you want. A lot of parsers, like the xml_parse functions in PHP, can handle arbitrary XML input as long as it's "well-formed", that is, follows the syntax rules properly.

Because PHP passes arguments by value, you will be out of luck in most
cases -- by the time your debugging function sees the argument, it's no
longer tied to the calling scope. Michael Sims' example function works
only for variables in the global scope, which probably won't work for
anything complex enough to need its own debugging library.
> I'm trying to extend my library of debugging functions/procedures by

You may find what you need in debug_backtrace(). Alternatively, just pass
the variable name along:
function echo_var($varname, $varvalue) {
printf("%s: %s\n", $varname, $varvalue);
}
...Which isn't much of an improvement over a plain old echo/print. And if
that's good enough for Brian Kernighan, I'd hope it's good enough for you.

I wholeheartedly disagree. :) I think that optimizing for the sake of the programmer, the bug fixer, and the possible inheritor of the project is a /great/ idea. Servers keep getting faster, while the human attention span and rate of familiarization with code stays approximately constant, so optimizing your development time is at least as sensible as optimizing SQL select performance, which is probably better handled through well-chosen indexes anyway. Optimizing for the programmer usually translates into thinking about the humans who will need to interpret your code, and making it easy to pick up the gist of your intent. A 24-table join is not a typical characteristic of what I'd consider a well-planned DB schema, whose meaning can be quickly grokked by a newcomer to the project. If all those 24 tables store the same kind of data, then there's no reason to split them up. Of course, we haven't seen the specific usage of those tables in this thread, but I'm basing my posts on the assumption that it's better for the OP to have a "marbles" table with a "color" column, than tables named "red_marbles", "blue_marbles", 'green_marbles," etc. If that's not the kind of data we're talking about, then I stand corrected, and John Nichel's initial response is all that's needed. A huge table count is often evidence of a need for some refactoring. - michal migurski- contact info and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Why not use the existing mysqldump command-line utility?
function mysql_dump($db, $user, $pass)
{
return shell_exec("/path/to/mysqldump
--user={$user} --password={$pass}
--complete-insert --add-drop-table
{$db}");
}
Or, skip PHP entirely and place a call to mysqldump with a suitable
select-privilege-only username & password in a cron job, if you're on a
unix machine. I use the following shellscript to do periodic backups to
RCS repositories in /usr/local/var/backups:
#!/bin/sh
if [ $# -ne 3 ]; then
echo 'Usage:';
echo ' mysql-backup.sh ';
exit;
fi;
USER=$1;
PASS=$2;
DB=$3;
MYSQLDUMP=/usr/local/bin/mysqldump;

cd $BACKUP_DIR;
$MYSQLDUMP --user=$USER --password=$PASS --complete-insert --add-drop-table $DB >
$SQL_FILE;
the remaining lines can be ommitted if RCS isn't needed
if [ ! -f $RCS_FILE ]; then
echo "import" | rcs -q -i $SQL_FILE;

Right, but if the database's built-in backup tool is used rather than the filesystem, it ought to respect the read/write locks that are a natural by-product of using begin/commit to wrap your transactions. E.g., a call to pg_dump should be guaranteed to pull the database in an internally-consistent state, if the application logic uses transactions correctly.

If you call it via exec(), you can append an ampersan to detach the

fopen() can support streams, if your configuration allows it:
http://php.net/manual/en/function.fopen.php
Alternatively, you can use the socket functions to hand-roll an HTTP
request, in the event that you need stricter control over POST contents or
specific headers.
http://php.net/manual/en/ref.sockets.php
Or, if you're on a unix system, and curl's available as an executable, and
you consider exec to be a "standard" function, there's always this:
$response = shell_exec("curl http://www.example.com";);
I always use last method that in preference to the curl functions.
I find them incredibly overengineered. :)

It could be useful when retrieving real data is expensive.
I've been recently working with a data set that is derived from a
highly-relational database served over HTTP via XML. It's time consuming
to pull new information about a record and not all information is used
everywhere, so I've been using a structure similar to yours with a
lazy-load component -- the data source isn't actually accessed for a
particular piece of information until that piece of information is
specifically requested.
In the example below, properties one and two might refer to linked or
nested objects, each with a high cost of retrieval. The database access
code that is now in your initialize_customer() method gets split up into
logical chunks, and placed in the property_*() methods.
Paraphrased/contrived example:
class thing
{
var $id;
var $property_one;
var $property_two;
function thing($id)
{
$this->id = $id;
}
function get_property_one()
{
if(!$this->property_one) {
// perform request for property one,
// set $this->property_one
}
return $this->property_one;
}
function get_property_two()
{
if(!$this->property_two) {
// perform request for property two,
// set $this->property_two
}
return $this->property_two;
}
}

Use the single-quotes -- array references often work without them, but the
potential for conflict with constants and future PHP incompatibility is a
possibility. If you (or PHP) had a constant foo defined, it would behave
unexpectedly.

[PHP] Regular Expressions with symmetrical contents
Hi,
I'm trying to figure out an appropriate strategy for handling regexps
where I need to parse input like the following:
"{ {...} {...} (part I want to match) } more..."
...The catch being that thepart I want to match can contain escaped curly
braces, like so: "\{" and "\}" It's not enough to just check for the first
ending curly brace, using an expression like this:
'/{[^{]*{[^}]+}[^{]*{[^}]+}(.*)}/s'
= the part I'd like to match
...because there may be other curly braced content afterwards which should
not be matched. Regular expressions seem like they're not suitable for
this sort of input parsing, and I'm wondering if there is something else
out there, like a generic SAX parser for input other than XML. The input
I'm using is coming OS X text resources that are in RTF format, so I guess
an RTF parser would work too.
Any leads?

Re: [PHP] Regular Expression for a UK mobile phone number

Can you provide an example of numbers it rejects?
My answer was based on the simple fact that you were testing for numbers
that matched, and returning a rejection based on that. The regexp is
simple enough -- some examples of input where it fails would be good,
perhaps in a reduced case, like:
foreach($array_of_inputs_to_check as $input)
printf("input: %s, matches?: %d\n", $input, check($input);

Try this:
$regexp = "/447[0-9]{9}/";
if($_POST[mobile_number] != ''){
if(!preg_match( $regexp, $_POST[mobile_number] )){
$error = "Invalid Mobile Number";
header("Location:edit_rep.php?error=$error&rep_id=".$_GET[rep_id]."&client_id=".$_GET[client_id]."&rep_name=".$_GET[rep_name]."&client_name=".$_GET[client_name]."");
exit;
}
}
Also, your regexp is a little permissive; you can anchor it like so:
$regexp = "/^447[0-9]{9}$/";

I have heard rumors that remoting is supposed to be "deprecated" in the next revision of flash, but I'm not sure how reliable those reports are. Remoting with AMFPHP is speedy and easy, but you may be a little better off using XML - it's definitely chatty, but the API is stable on both sides, and there's no reverse-engineering voodoo associated with it. ----- michal migurski- contact info and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I thought you might place the flush() in a while() loop, and keep outputting whitespace until you cross whatever buffering limit the server imposes, but of course this won't work since you can't send output before the Location: header. That's probably the source of the problem you have - with nothing to flush, flush() won't work. Two options I immediately thought of to drop into the background: start a command line php process, using exec() or the like with the usual '&' at the end to drop into the background -- I see Rich has just suggested this. If you want to avoid the database route, use a filesytem queue to signal cron on its next run. Tell the user that "their request will be handled in the order in which it was received" and then cron can check a file or directory for new requests, and process them. I don't think the minute delay is an issue, because the whole thing takes an hour, so what's a minute or two here or there? Jus let the user know they're in good hands and get to it when you get to it. - michal migurski- contact info and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Why not delete that part of the 3rd party code then? Or send your Location
header before you call it? Curl won't help you here, for the same reasons
that fsockopen won't work.

That won't get sent to the browser, it will get sent to 192.168.0.2, which
is (I guess) some machine behind your router. You can't initiate a TCP
connection -- what fsockopen does -- with the client's machine.
I'll ask even though you said not to - Why doesn't header() work?

Re: [PHP] Image Storage
>I am creating a system to allow users to upload images to the site. >Would it be better to store the images in a MySQL table, or having it >save the images to a directory on the server? Anyone have any >suggestions on this? Pros? Cons? Depends on the details of your situation - I've generally preferred to store image in the filesystem. A few hosts I've used have administrative limits on the size of a BLOB field, so storing images in the filesystem was mandatory. If those images are stored within the docroot, you can also just refer to them by URI and let Apache handle all the appropriate headers and such, or if you're strapped for CPU you can even use a completely different webserver (thttpd, apache without PHP, etc.) to serve them. If they're stored in the database or outside the docroot, you can control access to them more easily. Keeping them in the database also means that you don't have to worry about various filesystem considerations, like keeping a world-writeable directory or potential undesired access from others users in a shared hosting environment. ----- michal migurski- contact info and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Gecko/Moz based browsers will ignore a stylesheet that lacks the appropriate Content-Type header, so definitely make sure it's there. Regarding the caching, I think just setting up the appropriate cache-control headers should make it indistinguishable from a regular, static CSS file. ----- michal migurski- contact info and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
