Doc #71713 [Opn]: Array_Key_exist is not recursive

Edit report at https://bugs.php.net/bug.php?id=71713&edit=1 ID: 71713 Updated by: cmb@php.net Reported by: martin at wenhaston dot net Summary: Array_Key_exist is not recursive Status: Open Type: Documentation Problem -Package: Documentation problem +Package: Arrays related Operating System: N/A PHP Version: Irrelevant Block user comment: N Private report: N New Comment: Well, PHP doesn't have multidimensional arrays; it's just that an array value can be an array. However, that doesn't mean that a key that exists in such an inner array belongs to the outer array. Therefore the documentation is not in error, in my opinion.

Only searches first level of array. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71713&edit=1
