replace existing function in php

ChicoMendez

hi

im using a CMS and i want to change a function without hacking the core

the function is mosformatdate()

id like to include a file that will ensure that my mosformatdate() is used and not the function from the API.

however having two functions of the same name will give us an error !

any way of replacing the first one?

tnx

Check out the override_function() function that comes with the PECL libraries.

Example:
[php]
<?php
function get_two($i) {
return 2;
}
override_function('get_two', '$i', 'return 3;');

echo get_two(1); //This echos "3"
?>
[/php]
If the above mosformatedate() function takes a single arg (say, $date), then in your include file you'd write something like:
[php]
<?php

function my_mosformatdate($date) {
//Insert action here
}

override_function('mosformatdate', '$date', 'my_mosformatdate($date);');
?>
[/php]
So every time someone calls mosformatdate(), the args get passed to my_mosformatdate() instead.

Depend on how they're set up.

Assuming that you've tried to use this and gotten an error then they'll need to recompile PHP with the php_apd module (afaik).

If it's a Windows environment then it's just a matter of adding the php_apd.dll extension to php.ini. I Windows for the simplicity of that.
