ID: 37047 Updated by: derick@php.net Reported By: karoly at negyesi dot net Status: Open -Bug Type: Variables related +Bug Type: Documentation problem Operating System: Irrevelant PHP Version: 5.1.2 New Comment: No, there is a difference between definition and assignment. The variable is overwritten by the static-call during compilation. The value is only assigned when the assignment is actually done. In Jakub's last example, the code never hits the assignment statement. In the original report, the "static $storage" definition is done twice, and during the 2nd time the original $storage static definition is destroyed. The static fetch in the return statement will therefore not work. I'd say this should be documented... It wouldn't be hard to add a notice for this though. Previous Comments: ------------------------------------------------------------------------ [2007-08-20 10:42:39] vrana@php.net If static variables are resolved in compile time then <?php function storage($key) { return $storage; static $storage = array('a' => array('x', 'y')); } var_dump(storage('a')); ?> should give an expected result. ------------------------------------------------------------------------ [2006-04-12 08:31:01] tony2001@php.net It's the same as <?php exit; class Test { } ?> The class will be still declared, even though there is an exit statement before the declaration. It doesn't mean that it's "executed", because there is a big difference between "execution" and "compilation". ------------------------------------------------------------------------ [2006-04-11 22:44:27] karoly at negyesi dot net Hint. If you doc this please doc everything as well that executes at compile time. It will be a very interesting handbook page... ------------------------------------------------------------------------ [2006-04-11 22:38:31] sean@php.net Sorry. I misread. You're right (-: S ------------------------------------------------------------------------ [2006-04-11 22:37:29] sean@php.net see: http://php.net/return "the return() statement immediately ends execution of the current function" (It's already documented.)
