#41814 [Opn->Bgs]: String comparison changed

ID: 41814 Updated by: tony2001@php.net Reported By: thomas dot hebinck at digionline dot de -Status: Open +Status: Bogus Bug Type: Scripting Engine problem Operating System: Linux PHP Version: 5.2.3 New Comment: The current behaviour is correct. >The two integers are not the same They are not integers in the first place, they are floats. Remove the quotes and you'll get the very same result. Previous Comments: ------------------------------------------------------------------------ [2007-06-27 09:10:39] thomas dot hebinck at digionline dot de The problem is, that the behaviour changed from 5.2.0. to 5.2.1. The two integers are not the same - they are just both out of range. It seems that PHP 5.2.0 didn't convert strings with out of range integers to integer while comparing, but PHP 5.2.1 does. ------------------------------------------------------------------------ [2007-06-27 08:23:44] tony2001@php.net Thank you for taking the time to write to us, but this is not a bug.
