PHP 4.0 Bug #4552 Updated: references inside functions work with GLOBALS, not global

ID: 4552 Updated by: stas Reported By: bill@rsv.ricoh.com Status: Closed Bug Type: Scripting Engine problem Assigned To: Comments: This is not bug. It goes as follows: 1. "global" means local ones become pointers to global ones 2. local fruit becomes pointer to the same as local rock (which is "granite") 3. global rock becomes pointer to the same as global fruit (which is "apple") but local rock (and thus fruit) still point to "granite" 4. Now when function exits, local $fruit and $rock are destroyed, and both $fruit and $rock point to "apple" Think about it as if all variables in PHP are pointers to some entities. Ask on the list if you need more guidance. Full Bug description available at: http://bugs.php.net/version4/?id=4552
