Bug #53525 [Opn->Bgs]: php version 5.3.0 - error in unset var for when used in function

Edit report at http://bugs.php.net/bug.php?id=53525&edit=1 ID: 53525 Updated by: cataphract@php.net Reported by: shoja dot mehrdad at gmail dot com Summary: php version 5.3.0 - error in unset var for when used in function -Status: Open +Status: Bogus Type: Bug Package: Variables related Operating System: test in windows vista PHP Version: 5.3.4 Block user comment: N Private report: N New Comment: Unset deletes the function local variable $array, not the global $b, despite $array and $b being in the same reference set. This is by design. When $array is recreated it already lost its connection to $b. Note that $array and $b point to the same data, but $array doesn't "know" which other variables (in this case,the global $b) point to this same data its pointing, so it cannot really unset $b.
