Unset a function?

[rossco_2004]

Is there a way in PHP to unset/delete a function that's already been made, so that I can reuse the name?

Reason is because in vbulletin3.5 there's the plugin system which i want to use to edit a function but there's no hooks in that function,so what i want to do is just copy/paste the code, make my edits, and put it into a plugin that cmes after the function has been made. Problem with just creating it is that i get the function already exists cannot redeclare message.

Thanks. :)

I don't think it's possible but of course I might be wrong (:

i know u can 'overwrite' functions in JAVA, but im not sure about PHP.

sorry dude!

you can't do it i don't think. first of all, deleting the function would null all of the variables which would make the program disfunctional.

EDIT: using the parent thingy might work

Or just make your edits directly into the VB function

I'm trying to keep the forum file-edit free for ease of upgrading...

This is the only file edit the forum has atm, i'm just trying to make it into a plugin so there will be none to worry about.

Well if there no plugin hooks in that function there is other way unfortuntly. Just make a backup of the file and edit it

You can use rename_function

<?php
rename_function('original_name', 'new_name' );
?>

and then redeclare the original function.

override_function may work too.

I tried rename_function. Here is the code I used:

//Rename the old function
rename_function('strip_quotes','strip_quotes_non_nested');

But then I get this messsage on the forums:

Fatal error: Call to undefined function: rename_function() in /home/filesh/filesharingtalk.com/html/vb3/global.php(233) : eval()'d code on line 156

:(

override_function and rename_function are part of the Zend PHP Debugger, so they are not part of the standard PHP package ;)

You might be able to use the method below, as described on: http://www.experts-exchange.com/Web/Web_La...Q_21615087.html

You can indeed call functions dynamically:

function function1(){
 echo "1";
}

function function2(){
 echo "2";
}

$i = "function2";
$i(); //  displays 2;
