Bug #44990 [Nab]: array('word')==array(0) -- true

Edit report at https://bugs.php.net/bug.php?id=44990&edit=1 ID: 44990 Updated by: nikic@php.net Reported by: design at apostolstudio dot com Summary: array('word')==array(0) -- true Status: Not a bug Type: Bug Package: Scripting Engine problem Operating System: Windows XP PHP Version: 5.2.6 Block user comment: N Private report: N New Comment: @radamanf: He is comparing with == so all array elements are also compared with ==. And as in PHP 'word'==0 they are considered equal. Are you suggesting that when you compare arrays with == the elements should be compared with ===? That makes no sense to me.

So if String is '' and Int is 0 or '1' == 1 '2' == 2 .. etc. only in this cases === is necessary to tell VARIABLE TYPE difference. It's so obvious, why I'm explaining all this to you ?! You should know this better than me!
