Edit report at https://bugs.php.net/bug.php?id=63201&edit=1 ID: 63201 Updated by: yohgaki@php.net Reported by: brainreflex at gmail dot com -Summary: PHP 5.4 and Function Overloading +Summary: Function overloading with namespace -Status: Open +Status: Verified Type: Bug Package: Unknown/Other Function -Operating System: OS X 10.7.5 +Operating System: * -PHP Version: 5.4.7 +PHP Version: * Block user comment: N Private report: N New Comment: http://3v4l.org/0VGGt Previous Comments: ------------------------------------------------------------------------ [2013-04-21 21:14:38] sjaillet at gmail dot com It's pretty annoying since this feature allowed a king of monkey patching in PHP 5.3 for writing tests cases. With PHP 5.4 & 5.5, redefining functions only work in the same file like in the follwing example: <?php namespace custom; var_export('hello'); //hello eval("namespace custom; function var_export(){echo 'foobar';}"); var_export('hello'); //foobar ?> ------------------------------------------------------------------------ [2013-04-20 00:50:18] sjaillet at gmail dot com Looks like it's an introduced bug since redefining functions still works well when functions had been called in the same file like the following : <?php namespace custom; var_export('hello'); //hello eval("namespace custom; function var_export(){echo 'foobar';}"); var_export('hello'); //foobar ?> ------------------------------------------------------------------------ [2012-10-02 15:26:53] brainreflex at gmail dot com Description: ------------ 5.4 doesn't allow to redefine function if bult-in function had been called before. It's a bug or omission of documentation For more details look at http://vatson.com.ua/blog/2012/10/01/php-5-dot-4-and- function-overloading/ Test script: --------------- https://github.com/vatson/php-experiments Expected result: ---------------- The same behavior for both versions ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63201&edit=1
