#47213 [Opn->Bgs]: include rename_function() in standard library

ID: 47213 Updated by: johannes@php.net Reported By: rasmus at mindplay dot dk -Status: Open +Status: Bogus Bug Type: Feature/Change Request Operating System: all PHP Version: 5.2.8 New Comment: It's here for people who _really_ want it, but we certainly won't make this a default function as 99% of the probable use cases are bad deign of PHP applications or other mistakes. In your case see spl_autoload_register() which does exactly what you want. Previous Comments: ------------------------------------------------------------------------ [2009-01-25 16:35:00] rasmus at mindplay dot dk Description: ------------ Please consider including this function in the standard library: http://us3.php.net/rename_function This would enable techniques as shown below. I know this is a duplicate of feature request #37078, which was bluntly rejected without explanation, before anyone had a chance to review or comment on this idea. Reproduce code: --------------- <?php // example - // install an autoload handler that preserves an existing handler: if (function_exists('__autoload')) { rename_function('__autoload', '__autoload_old'); } function __autoload($class_name) { if (function_exists('__autoload_old') { try { __autoload_old($class_name); catch ($e) { // my own autoloader here.. } } } ?> Another example would be the ability to extend existing PHP functions with new functionality, like calculating default arguments or enhancing the behavior of certain functions. Example: the array_chunk function only works with real arrays - you could override it with a function that works with iterable objects as well. Expected result: ---------------- This would work - you could override this magic function and preserve any existing autoloader. This would enable you to combine autoloaders from different projects. Actual result: -------------- The function is not generally available on standard PHP installations. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=47213&edit=1
