#47213 [NEW]: include rename_function() in standard library

From: rasmus at mindplay dot dk Operating system: all PHP version: 5.2.8 PHP Bug Type: Feature/Change Request Bug description: include rename_function() in standard library 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 bug report at http://bugs.php.net/?id=47213&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47213&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47213&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47213&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47213&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47213&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47213&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47213&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47213&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47213&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47213&r=support Expected behavior: http://bugs.php.net/fix.php?id=47213&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47213&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47213&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47213&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47213&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47213&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47213&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47213&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47213&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47213&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47213&r=mysqlcfg
