Hi gang:

Do you use a Mousepad?

My reason for asking is that I've used a Mousepad ever since mice first came

Now that mice are optical (no balls), Mousepads are not really needed -- or so 
I'll told by the college -- you see, they don't provide Mousepads for their 
student's computers.

As such, I wondered what's the percentage of programmers still using a Mousepad?

Secondly, are Mousepads used primarily by older programmers (like me) while 
younger programmers don't use Mousepads, or what?

[PHP] Does Scope-Resolution Operator Always Follow 'parent'?

[Eric James Michael Ritz]

Hello everyone,

I have a question about the `parent` keyword: is there any valid
situation where it can appear without the `::` operator following?

I am asking to fix a bug in php-mode[1] for GNU Emacs.  Consider the
following code:

echo $parent;
echo parent::$foo;
echo $this->parent;

The mode incorrectly highlights `parent` in the final line as if it
were the keyword, but PHP itself treats it as a member of an object.
My idea for fixing this incorrect syntax highlighting is to only treat
`parent` as a keyword if the `::` operator follows it.  But I want to
make sure that this assumption is correct.

Thanks in advanced for any help!

[PHP] A Recent Emacs Mode for PHP

[Eric James Michael Ritz]

Hello everyone,

I do not know how many PHP developers use GNU Emacs for writing code.
But I assume it must be a decent amount since there are multiple PHP
modes for Emacs floating around the Internet.  For months I have
worked to improve one of those modes, what seemed to be the most
popular: http://php-mode.sourceforge.net/

Of course, not all of the improvements are my own work.  Many people
have been kind enough to contribute bug fixes and features.  This is
the version of php-mode which I maintain:

https://github.com/ejmr/php-mode

I simply wanted to share this updated mode in case any developers
using Emacs find it useful.

[PHP] output compression when host has disabled mod_deflate, mod_gzip and php_value auto_prepend_file

[edward eric pedersson]

Hi

My host, Host Papa (yes, they are rubbish) has disabled mod_deflate,
mod_gzip and php_value auto_prepend_file so can't use them in
.htaccess file. I would move host but I did not realise this was the
case until I wanted to make use of them. I am tied in for three years
so need to find a workaround or live with it.

The site is built using CMS Made Simple (a php based CMS) and I am
using ob_start ("ob_gzhandler"); to compress the html output from the
CMS.

I want to compress the css and javascript external files as well but
without the apache options available I am wondering what other options
I have. The files are not massive, all but one less than 20k. Not sure
how much of a performance gain I will get but I thought it is worth
while asking the question.

One solution I have on my mind is to call a php script that pulls in
the css and js files and compresses the output e.g

http://my.domain.com/stylesheet.php?file=/path/to/stylesheet.css";
/>

stylesheet.php
--


--

Similar code for javascript with different content-type.


A few questions:

1) Will apache cache the full url or the url minus the query parameter?
2) Are there any performance benefits as there is an overhead in
calling the PHP file?
3) If the PHP call is cached is it cached with the file query parameter?

Many thanks for your help.

$dteStartDate[$intCnt] = new DateTime($row[10]); $dteEndDate[$intCnt] =new 
DateTime($row[11]); $interval = 
$dteStartDate[$intCnt]->diff($dteEndDate[$intCnt]); echo

well then look deeper in the question:  

"I have a page I am trying to create where I am comparing the values of two

all needs to do is modify his query.

When I try this method:

 

$interval = $dteStartDate[$intCnt]->diff($dteEndDate[$intCnt]); I get the

" Fatal error : Call to undefined method DateTime::diff() in

I looked at this answer and see the date is from an array of a database and not 
2 fields with in the table.
While the DATEDIFF() is very useful in queries this will not help you unless 
both fields are in the table.

Try this example

$dteStartDate[$intCnt] = new DateTime($row[10]);
$dteEndDate[$intCnt] =new DateTime($row[11]);
$interval = $dteStartDate[$intCnt]->diff($dteEndDate[$intCnt]);
echo $interval->format('%R%a days');

[PHP] Question about date calculations

[Eric Lommatsch]

Hello List,

 

I am using PHP version 5.2.6.

 

I have a page I am trying to create where I am comparing the values of two
MySQL date fields with the current date. One of the MySQL Date fields is a
class start date, the other is the class end date.

 

First I need to calculate the number of days between class start and end
date. Then based on the number of days between these to dates I have to find
out how close the current date is to the class end date.

 

So far in looking at the functions that are available at
http://www.php.net/manual/en/ref.datetime.php I have not been able to figure
out how to do what I need to do.  Below is a snippet showing approximately
what I am trying to do.

 

=($dteEndDate[$i]-7) &&
$dteCheckDate<=($dteEndDate[$i]+1)) && $intDayCnt<16)

...

?>

 

My start date is 12/26/2011, the end date 1/8/2012 so the value for
&intDayCnt should be 13, but it is coming up as 0.

 

Also the check date which is 12/29/2011 is being calculated as after my end
date.  Can someone point me in the direction of what I need to do to have
the comparisons I am doing work.

 

Eric Lommatsch.

Hi Adam,

Thanks for the reply, noted!  I was coming from the angle that I've
had to deal with a lot of code that is 2000 lines of
php/html/javascript inside heredocs, mixed quote escaping, etc.  I was
hoping to prevent that from becoming a new thing in this persons code
if that was the case.  Apologies for assuming.

To all the people who responded to this thread:
It is 2011 - please stop writing code like this.

To the OP:
I'm glad you're asking questions and realizing you're not happy with
your current abilities and suspect there's a better way.  I've read
the replies in this thread and feel a bit let down.  Use a templating
language - yes, I understand that is what php is for - but I won't go
into it.  You should not be echoing, printing, or any other method of
concatenating html dealing with escaping quotes inside your php logic
code.  Please separate your concerns.

Not sure what that means?  That's OK!  If you want to move forward,
look up how modern frameworks deal with this issue using their views
or template views.  You don't have to use a framework if you do not
want to, that's perfectly fine.  If it works, it works.  But in the
end, it the separation of logic and html is essential to code
maintenance.

I saw your post on that the other day - looks like there's a native

Not sure what is happening inside "process row here," but I'm sure
that is where your issue is.  Instead of building some giant structure
inside of that while statement you should flush it out to the screen.

[PHP] Re:

[Eric]

Thanks Very much I used,
preg_match('/[[:punct:]]/', $_POST['username']) !== 0
and it works without errors. The reason I can't just use
is_file which I wish I could is because windows doesn't allow question marks
or some wierd character. It decides to not allow php to make the file if there
are odd  ball characters. It is a very unfortunate mistake in my code that I
wish php would ignore and just make the file "?".

[PHP] RE: How can I check for characters in a $_POST[] variable?

[Eric]

if(preg_match('(.*)^[A-Za-z0-9]+', $_POST['username']) !== 0) {
echo "";
echo "Username must only contain A-Z and 0-9";
include("register.html");
exit;
}

I used the code above but I now get this error message

Warning: preg_match() [function.preg-match]: Unknown modifier '^' in 
C:\Documents and 
Settings\iceweasel\Desktop\XAMPP\relik.ath.cx\forum\register.php on line 2

I don't like to run php with errors off so I wanna ask how I can fix this.

[PHP] How can I check for characters in a $_POST[] variable?

[Eric]

I have this problem when using php because my computer recognizes
the characters "." and ".." as an existing file when I use file_exists. Also
I want to check $_POST["username"] for characters other then A-Z a-z and 0-9.
If it contains anything other then, I would like to prompt the user but
I can't seam to use foreach properly and I don't know how to itterate
through the post variable with a for loop while loop or do while loop.

Just out of curiosity, where are these ids coming from?  Doing a raw

Flush all buffers you have.  Sometimes you have to do nasty hacks like
send a certain number of characters.  Execution will still continue
along after your buffers are send if it is still blocking for a query.

You might have better luck if you search for 'comet' or 'long polling.'

Traversing the internet is one of the most expensive IO operations
that can be performed.  The OP should try and split the work into
several processes and utilize async connections via a mechanism like
curl_multi [1].  Doing 1,000 connections one at a time is abysmal if
you're blocked for even 3 seconds per connection.

I'd work by making a two step process that has one cron job for
constantly fetching/updating feeds into a store & then another process
that constantly checks for updates inside aforementioned store.

Just to throw my two pennies into this - I believe that all browsers
should auto-upgrade.  The browser has become the most important
application on desktops and it is remiss of all parties involved to
allow the masses to use exploitable out-dated software.  If someone is
paranoid about their supposed privacy, afford them the luxury of
finding ways to use software that has known defects.  I entreat you to
consider how much time and pain this would have prevented over the
last decade.

Hello,

Impressive stats and has me a bit intrigued!  Just out of curiosity,
does your daemon use a heavy amount of object orientation in it or is
it mostly procedural codebase?

You can implement caching at so many levels of the app that using a
prepared statement should be at the lower spectrum of your worries.
It is too easy to forget calling escape whether it be for a DB or
output to the browser as proven by all the various bug trackers and
hacked websites across the net.

Just to drive this point home, if you do a quick search on Secunia for
'SQL Injection' [1] you get 4,158 advisories.  Worth the risk?

I'm sorry but this is absolute rubbish.  I used to write my queries by
hand, but over time you start to realize that perhaps, maybe writing
out thousands of identical lines of code over hundreds of projects
might not be an efficient usage of time.  If you have performant
requirements, that is one thing and can easily be overcome with slight
deviations on a case by case basis.  Most of the time, contrary to
your position, things just need to work and be completed quickly.
What is the more common question from clients: why is this so slow,
or, client asks why is this not finished yet?

I do like the half-hearted diatribe against ROR, which I will assume
is a wildcard, allow any language/framework combination to stand-in.
The real take-away message here is that you're trying to paint
everything with the brush that you see the world in, while the reality
is that not everyone has your requirements.  Personally, I don't enjoy
trying to mess around with ill-conceived, backwards-compatible
adhering designs from 12 years ago.  I understand that growth is
organic and deal with it on a daily basis in my own projects.  Hence,
I use a framework and other tooling that allows me to complete jobs in
a tidy and orderly fashion.  If I need something a little more
cutting-edge I can always drop down lower on the stack to bypass PHP
with other techniques like caching or bypassing the framework
altogether.  To say that all frameworks are a complete waste of time
and will only (absolutely) end in failure is quite a disservice to
anyone who reads this list.

I've seen too many people over the years try and rally against common
sense practices like using prepared statements for perhaps a marginal
gain of performance on one page while their load averages are 0,0,0.
One archived post could be the cause of 50 hacked websites.  This is
not the position people - or, mentors, if you will - should be taking.
 Same with other tools that allow developers to crank out projects
orders faster.

This post isn't meant to be some vitriol inspired rant, but rather a
sincere wake-up.  Imagine the intended audience of php-general and ask
yourself if you're doing harm.  An example:  when I say harm, every
other framework I have seen from php (ok, ok, ZF makes you call
escape), ruby, python, and node all escape variables in
templates/views by default.  PHP is the only one that lets you echo
out XSS out of the box.  Of course, with diligen

Hello,

There is terminology in place for what you're trying describe.  First
take authentication, the ability to log into a system.  Second would
be authorization, the abilities a user has.  With these terms you can
do some further research on the subject.

For reference in a lot of projects for authentication I use
Zend_Auth[1] and for authorization I use Zend_Acl[2].  Hopefully
linking to them will not contribute to further confusion.

You can use mb_substr [1] with a UTF-8 encoding to get the single characters.

I use it quite a bit over the various projects I maintain.  It allows
subjects to trigger events that observers can process if they're
interested, or better yet, completely ignore.  This allows
standardized code bases to create nice hooks that allow extensibility
without needing to place one-off code inside the main project.

A quick example might be on saving a record in your code, it triggers
an event, then an observer in a custom site watches for said event and
injects/updates a search entry in Lucene.  This way one site can have
a custom search engine that another site might not need.

I started off with the concepts I found in
http://examples.stubbles.net/docroot/events/ but created my own
because I wanted something stand-alone.

Pretty say to see a lmgtfy response, so I'll try and provide something
slightly more worthwhile.  First off, what is so bad about the php.net
documentation?  If it is over your head, then I'd say get yourself
some books and study fundamentals.  Granted, you don't need to buy
anything as searches will yield the proper results--of course this is
much more difficult if you don't know the terms.  I was confused at
first too, but I persisted and learned a few tricks.  I started off by
studying open source projects & reading the code/searching for the
method names it used.  Look around on Github, it is all there for your
consumption!  Just FYI, my favorite book was Head First Deign
Patterns.

I think the best part about coding is that there is no "right way."
There are millions of solutions to these problems whether they be
classical, prototypal, functional, or whatever. :)  Either way, good
luck!

 I have not been worked with mysql multi-insert before.
But just did a simple test on my mysql 5.0 copy.

I assume that you are using MyISAM table and will lock its read, writel
when inserting data.

When multi-insert was done, and did a select last_insert_id(). I saw that
only
the first inserted id was returned. Please take a look the following steps:


mysql> select * from temp;
Empty set (0.00 sec)

mysql> insert into temp (firstname, price) values ('dd', 10), ('cc', 3),
('bb', 99);
Query OK, 3 rows affected (0.00 sec)
Records: 3  Duplicates: 0  Warnings: 0

mysql> select last_insert_id();
+--+
| last_insert_id() |
+--+
|1 |
+--+
1 row in set (0.00 sec)

mysql> insert into temp (firstname, price) values ('dd', 10), ('cc', 3),
('bb', 99);
Query OK, 3 rows affected (0.00 sec)
Records: 3  Duplicates: 0  Warnings: 0

mysql> select last_insert_id();
+--+
| last_insert_id() |
+--+
|4 |
+--+
1 row in set (0.00 sec)


So, let's say three records was inserted, and the first inserted id was 1.
You get id from 1 to 3.

! This will not work on transaction-based insert !

Just a thought and tested on mysql but not on php.

How about RESTful like checking ?

First, I am sorry for not getting back to this yesterday. I had some other
things come up.

As far as I know this website is using WSDL. I know that one of the early
issues I ran into in trying to get this to work was not having the wsdl.php
file in the path.

That having been said are you talking about the wsdl file on the server that
is providing the service or are you talking about the wsdl file on the system
hosting the webpage. 

I can get everything to work correctly when I am working from our internal
development server. But when I attempt to put the file on the hosted site our
clients would ultimately be using I am getting the connect error. 

I have compared the wsdl.php files on these two servers and neither of them
have specific information about the port in them.

Here is the code that I am using to connect to the webservice:

$webservices_uri =
"http://xx.xx.xx.xx:8080/jasperserver/services/repository";;

Here is the code where I am trying to connect:

function ws_checkUsername($username, $password)
{
$connection_params = array("user" => $username, "pass" =>
$password);
$info = new SOAP_client($GLOBALS["webservices_uri"], false,
false, $connection_params);

$op_xml = "".
"";

$params = array("request" => $op_xml );
$response = $info->call("list",$params,array('namespace' =>
$GLOBALS["namespace"]));

return $response;
}

This is working when I use the IP address of the server behind the firewall,
but when I try to use the address that is open through the firewall it is not
connecting. I can connect to the external IP address by entering it into the
browser and it does ask for the username and password.

I have connected to a clients computer that is remote from our office and I
am able to get to http://XX.XX.XX.XXX:8080. I probably should have mentioned
that when I try to get the webservice outside of the PHP site I am developing
I can get into that just fine. It is just when I try to use the PHP SOAP
client to access the webservice that I am getting the issue.

[PHP] SOAP connect error

[Eric Lommatsch]

Hello,
 
I am working with the SOAP package of PHP and I am trying make a connection
from a hosted website to a server in our office. 
 
I can get to the server perfectly fine from within our office, but I cannot
connect from the eternal site.
 
I have checked and I am certain that the firewall for the server is open.
When I attempt to use the login page that I have created for the website I am
getting the following error message:
 
Connect Error to XX.XX.XX.XXX:8080
 
Where XX.XX.XX.XXX mask the actual ip address of the server. I have tried to
interogate all the values that soap_fault documents that it can return and
the only information I have been able to find beside the above message, which
is the $errorstring, is that my $faultcode = "HTTP".
 
The information that I am getting is very cryptic. if I include our ip
address when I search I get no results. If I put in connect error :8080 I get
millions of meaningless results.
 
Can someone please help to figure out how to get more meaningful information
from soap_fault for this problem so that I can figure out how to fix it.
 
Thank you

I have just been bulit a simple test script.
It works for me with a feof call if the stream was at end of file.

I did a sample test from the manual with fopen like this,

Sorry for that !   I'am too lazy !!
And that's just for easy looking the code.

I actually use this,

[PHP] exception throw from __autoload could not be catched on php 5.3.1

[Eric Lee]

Hi php-dev pros,

I got an issue about catching exception throw from __autoload on php 5.3.1.

The manual state that exception throw from __autoload could be catched with
try.. catch statement same as the normal flow.

But I'can archive that even I have copied the same sample code from the
manual.

Here are the code segment.

[[[
function __autoload($name) {
echo "Want to load $name.\n";
throw new Exception("Unable to load $name.");
}

try {
$obj = new NonLoadableClass();
} catch (Exception $e) {
echo $e->getMessage(), "\n";

That should be on the stackoverflow.com
It compare the string parsing with or without variables embeded
and the important of comma operator when ` echo ` data

use
echo 'something', 'other'

but not
echo 'something' . 'other'

Re: [PHP] Reliable way to identify Ogg types?

[Eric Lee]

Hi Micheal,

One of way for this should be by checking the header of the file with its
OggS magic number.
You may take a look at this page to see if it could help !

http://en.wikipedia.org/wiki/Ogg


But I'am confused that the mime type should be enough what type of data its
coming !
Are there are any more  things you need to concern ?


Thanks,

Paul,

I seem that you should missed the required underscore " _  "
It should the __get() but not _get().
Shall this help ?

And here is a quick test !!

[ [ [
class test
{
public $varname = 1000;

public function __get($name)
{
return $this->init($name);
}

public function init($name)
{
return new test();
}
}

$t = new test();
$db = $t->database;
if (is_object($db))
{
echo $db->varname;
}

HI Angus,

+1 I agree on what Paul already said .
As in fact you were just to sent out low volume mails.
Create a table and queue all pending mails in that then use windows
scheduled tasks to perform the actual work
if that is not a real-time mail.


One thing to note, php on windows does't support specify username and
password.
But only hostname / IP Address and port only.


I can not help much
but just few more suggesions.

Hope these help

Re: [PHP] How to get a string from C library into PHP via SWIG?

[Eric Fowler]

I will expose only one function, prototyped like the foo() example I described.

cstring.i is not implemented for a PHP target (wah).

I think I will go the shell approach. I have enough time in this already.

A little more information: my crashes all relate to handling the char
datatype. Floats and ints are happy.

I suspect that a char type in PHP is not the same as a char type in C.
But I am not sure at all.

More recently I have used cmalloc.i to allocate arrays of chars and
floats. The floats are happy, the chars crash upon allocation.

Re: [PHP] How to get a string from C library into PHP via SWIG?

[Eric Fowler]

This is going to the list per Nathan's suggestion.

I confess I am doing this the hard way because I want to get a handle
on how to pass across that boundary.

My current angle of attack is to use the malloc.i functions in swig to
handle those strings.

I will keep you all posted. I know you care. :-)

Eric


I have a software library that parses strings into a C language
structure. It is a utility for C programmers.

It contains a utility function that takes the output structure and
formats it as a string for display.

The goal is to demonstrate the functionality by permitting users to
enter strings into a text box and press a button.
The string will be passed into my code, parsed, formatted as a
different kind of string, and returned, where it will be
displayed on the web site.

The code is being shipped as a Windows DLL but for the web site I am
working with Linux dynamic libraries (*.so).
I am able to call functions within the binary from PHP now, but
pointers within PHP are not working far less crossing the
PHP/C Line Of Death without dying.


please keep the responses on list for the benefit of others.

well, if you have an .so, honestly i might spend the effort to wrap it
up in a simple extension.

but if you want to roll something out quickly, i would probly just
invoke it over the shell via shell_exec() or similar.

i cant imagine what sort of noticeable impact you would see in
performance going over the shell in this case.  honestly, i think the
question is how much work do you want to do.  also, do you intend to
share this functionality w/ other php programers, that might be an
argument for an extension.

do you already have a C based program that loads up the library from
the cli and uses STDIN / STDOUT, if so i think going over the shell is
a no-brainer..

[PHP] How to get a string from C library into PHP via SWIG?

[Eric Fowler]

I have a need to call a C language function from a PHP script.

The function, which I wrote, looks like this:

/*
* foo(): Takes a string in sIn and writes another string into sOut
according to what is passed in, and the
* value at *pcch. Will not write more than *pcch bytes to output,
including null terminator.
* Upon return, *pcch contains number of chars written to sOut.
*/
void foo(const char * sIn, char * sOut, size_t * pcch);

So basically I need to pass down a string, and get back a string.

I have been using swig but clearly I ain't getting it (I am good in C
but new to PHP). Lots of warnings, crashes, and so on. No happiness.

The swig docs show how to pass strings between python, java, etc., and
C, but nothing on C <---> PHP.

Can anyone help me with a fragment of sample code, or a link?

Thanks

Re: [PHP] MySQL Increment/Decrement

[Eric Lee]

Ben

It seems that you can just update the column with a update query like this,

update table set field = field + 1 where some condition

This might be the thing you need.

First off, take out those HTTP_POST_VARS lines. That's an outdated way of
accessing post variables, and is made useless by the next two lines that
follow it.

Second, the two lines you are using at the end there are for post data, but
you clearly use get data in the URL! If you have to accept the username and
password from both get and post, change the lines to use $_REQUEST instead of
$_POST.

Hi

PHP closes an open db connection when the script is done.

I've read somewhere that in PHP6 this behaviour will dissapear, is this
true? In that case using mysql_close() would definetly be best practice

A nice solution would probably be adding a end_mysql() or page_end() to
all pages and put whatever is needed into that function (mysql_close,
mysql_free_result, etc)



I can't say with any certainty whether that is true or not - but it 
certainly seems like it is false. Non-persistent connections are 
destroyed automatically by the garbage collector when no more references 
are detected. See 
http://au2.php.net/manual/en/language.types.resource.php#language.types.resource.self-destruct


That said, I believe it to be good practice to close any opened database 
connection. All my database methods are wrapped in a class, however, so 
I do this in the destructor.

[PHP] What is the best practice for adding persistence to an MVC model?

[Eric Bauman]

I'm in the process of implementing an ultra-light MVC framework in PHP. 
It seems to be a common opinion that the loading of data from a 
database, file etc. should be independent of the Model, and I agree. 
What I'm unsure of is the best way to link this "data layer" into MVC.


I've considered a few options:

*Datastore interacts with Model*

//controller
public function update()
{

 $model = $this->loadModel('foo');
 $data = $this->loadDataStore('foo', $model);

 $data->loadBar(9); //loads data and populates Model
 $model->setBar('bar');
 $data->save(); //reads data from Model and saves

}

*Controller mediates between Model and Datastore*

Seems a bit verbose and requires the model to know that a datastore exists.

//controller
public function update()
{

 $model = $this->loadModel('foo');
 $data = $this->loadDataStore('foo');

 $model->setDataStore($data);

 $model->getDataStore->loadBar(9); //loads data and populates Model
 $model->setBar('bar');
 $model->getDataStore->save(); //reads data from Model and saves

}

*Datastore extends Model*

What happens if we want to save a Model extending a database datastore 
to a flatfile datastore?


//controller
public function update()
{

 $model = $this->loadHybrid('foo'); //get_class == Datastore_Database

 $model->loadBar(9); //loads data and populates
 $model->setBar('bar');
 $model->save(); //saves

}

*Model extends datastore*

This allows for Model portability, but it seems wrong to extend like 
this. Further, the datastore cannot make use of any of the Model's methods.


//controller extends model
public function update()
{

 $model = $this->loadHybrid('foo');  //get_class == Model

 $model->loadBar(9); //loads data and populates
 $model->setBar('bar');
 $model->save(); //saves

}



Any input on the "best" option - or alternative - would be most appreciated.

I know you're more concerned with structure, but your checkInt()
method is arguably buggy/has an un-noted assumption. It accepts ints
formatted as ints and strings, but not floats:



*sigh* sometimes I really wish PHP allowed one to be a bit more 
heavy-handed with types (optional real type hinting would be nice).


I guess I only ever worried about string (from DB) and int (internal 
call) as in my specific use I would never be passing a float.
You make an excellent point however; I suppose in the interests of 
completeness, forward compatibility etc. I should take into account more 
possibilities. Perhaps I should just throw an exception in deposit() 
etc. if the argument isn't int and worry about converting elsewhere.


Also thanks for the sample TestCase code! I've never really thought 
about unit testing in PHP, despite doing so in Java etc. Reading about 
PHPUnit brought me on to phpUnderControl - interesting stuff!



Best regards,
Eric

Hi Paul,

As I agree some of your thoughts, I want to add my opinion also.
Yes the code should work. That is why we earn Money. If it doesnt work, then we are on 
fire. But things like OOP or MVC weren't invented for a better running code. They are 
invented so the codes will going to be much more clean, readable, reusable, maintainable. 
"Running codes" is not enough.

Eric asked about how his MVC structure looks. And we are trying to help what we know 
about MVC. He didn't asked if the code is fine for running. So giving an answer "The 
real key is, does it work, and can it be maintained" is not enough and not really 
helpful to him on MVC concept. If you need just a running and maintainable project, you 
don't need to use MVC (MVC is not all about that). We are not criticizing his code(the 
code is really fine(except injection problem :-) ) and very readable)


Eric,

As Martin said, All the business logic should be in Model. Controller should not tell a 
model "Save it to this database, select it from this table, use this 
db_adapter" etc. A controller is like a maestro of the system. It askes the model to 
play piano loud. But it wont say which key of piano, the model should touch.

I suggest you to read this online book about Zend Framework and MVC. Its really 
really very helpful to understand the concept. Also example codes are very 
clean and good.
http://www.survivethedeepend.com/zendframeworkbook/en/1.0


Take Care,

Mert
(sorry for my english)


Thanks for the link, it looks like an interesting read. Hopefully it 
will help me understand MVC better and hence allow me to improve my code 
design.

One observation. "Model" isn't a synonym for "Database Table" - models
can be anything that encapsulates business logic. Requiring all your
models to inherit from Model is probably a bad idea.


Thank-you for responding.

Out of curiosity, why is this a bad idea? Is it also bad for views & 
controllers?

Seems ok.

Just a thought:

 Your model seems to be coded just for retreiving data. IMO you should 
code it for all possible actions(insert,update,delete,select). And also it 
should run without any database calls(you may create a new bank user in a page 
and use it than throw it away, so you wont have to need a database to save it).

 Your model may be more useable when it can holds the data 
itself(without retreiving it from db first), after that a save() method may 
inserts/updates it to db.

Thanks for the response!

You suggested that the model should run without any database calls. Do 
you mean that they should not exist in a model (ie. a controller should 
instantiate /and/ populate a model), or rather that it should be 
optional (ie. each method only updates the state of the object, and 
load() & save() must be explicitly called to interact with the DB)?


Or am I way off track.

Eric

Thanks for your reply.

I was under the impression that sqlite2 was supported widely by PHP,
but sqlite3 seems only to be enabled on php 5.3.0 by default.

My concern now is actually that users may find that their hosting
service providers don't provide sqlite3 out of the box.

[PHP] new php script and sqlite

[Eric Boo]

Hi,

I'm currently using a text file to store data which the php script
will read and write back to. I've a few questions:

1) I'm thinking of using sqlite, but not sure whether this will be
widely available on most hosts, as I intend for the php script to be
deployed without needing to much with much configuration. Is sqlite
included with most php setups?

2) Should I be using sqlite 2 or 3?

Thanks for your time!

It should used on a second page.

You may also try put these line at top of page to avoid anythings sent before
your attachment headers

error_reporting(E_ALL);
ini_set('display_errors', 1);

Which browsers you used to test it and  their versions ?

You should encode the url before printing as usual way

You will need to add some headers to the page to popup the prompt, at least 
with 
these.

$filename = 'somefile.tif';
$filesize = filesize($filename);

header('Content-Type: application/force-download');
header('Content-disposition: attachement; filename=' . $filename);
header('Content-length: ' . $filesize);

L - O - L.  Little time you've got?  I just glanced at the list and
you seem to have a lot of time typing up incoherent messages.  I would
suggest reading some books on programming architecture instead of
typing out all sorts of silly emails that don't make any sense.  As it
turns out, if you know how to program in theory, the language itself
becomes moot.  Bai!

Har har.  This was not a mindless 411 scam.  It is a bit different
when an actual site people use gets hacked and their personal
information stolen.  I too received one of these emails and it was
very convincing.  It has my exact username from the Elance site and
was crafted in such a way that it seems this new site was a partner
with Elance somehow.

Have you actually profiled your code to see where the pain points are
vs saying 'module?'  Are you also running an opcode cache?  From there
you can use data, block, or full page caching.  Finally you can figure
out if you want to store it in flat files or memory.  I'd start by
knowing what is actually the slow part using Xdebug and nail a few
down.

There is no end all solution.  Some pages really don't have a lot
going on and are hardly updated so full page is fine.  Others might
have something that is hard to generate on a sidebar, so block caching
would be more suitable for that.  As previously mentioned, Zend_Cache
is up to the task.  There is also a PEAR package called Cache_Lite
which would work to if you're interested in file based caching.

PHPUnit + Xdebug has a really nice code coverage generation.  Perhaps
you could use the way phpunit hooks into xdebug to figure out likes
that get hit in the code base.  I don't know of a simple, ready-made
solution off the top of my head though.

The main thing to be aware of would be 'email header injection.'  Do
not allow returns/newlines in any of the mail header fields you
populate from user input.  Also require a valid email address and
verify that it has a valid domain name.

Next up would just be the annoyance of a client receiving tons of spam
messages.  There are a lot of automated programs crawling the web just
filling out every form it finds looking for vulns to exploit.  Even if
your form has no holes in it, the client will still get all of this
unwanted junk from the automated tests.  You can try to come up with
some clever ways of stopping that.

You're really opening a big can of worms here, but it'll be a good
adventure.  Just keep at it and try reading some real books on the
subject.

If you include a file, all of those variables are magically in the
current scope.  So when you include config.php inside your index.php,
you can use $dbconnect directly.

Use $this-> when you are inside a class using a dynamic call on a
method or property of that class.

class Foo {
  protected $bar;
  public function __construct() {
$this->bar = 'wee';
  }
  public function setBar($value) {
$this->bar = $value;
  }
}

Inside the class you would use this-> to reference bar or call any of
that classes methods/props.  Outside you would use it like this:
$foo = new Foo;
$foo->setBar('blah');

If you haven't used globals yet, please do not feel compelled to do so
now.  There are all sorts of ways of dealing with passing around your
application state.  Globals can be used by a skilled programmer of
course, but I'd shy away from them.

I'd also recommend reading some of these pages:
http://www.php.net/manual/en/language.variables.scope.php
http://www.php.net/manual/en/language.oop5.php


Hope this helps!

[PHP] Problems with an extension

[Eric A. Boney]

So I am developing a custom extension and I am having a issue. I have a header 
file that I need included in the project. If I #include the header file 
everything compiles and makes just fine, but after restarting the web server 
the extension won't load.

If I remove or comment out the #include of the header file everything still 
compiles and makes just fine, and after restarting the web server the extension 
is loaded just fine.

Does anyone have any idea what would cause the extension to refuse to load 
with the header file included?
