Re: Bug #15810: superglobals does not work with dynamic vars in functions

Hmmm, I saw that before when I tried to write code which is compatible with all versions of PHP. Something like <pre> <?php if ((str_replace('.','',phpversion())<410)){ define("__GET","HTTP_GET_VARS"); }else{ define("__GET","_GET"); } echo phpversion()."\n"; var_dump(${__GET}['some']); function a(){ var_dump(${__GET}['some']); echo __GET; } a(); ?> Output: 4.1.1 string(2) "aa" NULL _GET ----- Original Message ----- From: <goba@php.net> To: <php-bugs@lists.php.net> Sent: Friday, March 01, 2002 4:51 PM Subject: Bug #15810: superglobals does not work with dynamic vars in functions > From: goba@php.net > Operating system: win2k > PHP version: 4.1.0 > PHP Bug Type: Scripting Engine problem > Bug description: superglobals does not work with dynamic vars in functions > > See the attached example.
