From: Operating system: Windows 7 & Windows Server 2008 PHP version: 5.3.6 Package: Unknown/Other Function Bug Type: Bug Bug description:About operator === Description: ------------ In the PHP Manual it is said that: "$a === $b Identical TRUE if $a is equal to $b, and they are of the same type. (introduced in PHP 4)" But when I test like that: <?php $A=4; $B = '4' - '0'; echo '$A === $B '; echo $A === $B?"true":"false"; //Out put $A === $B true ?> I think $A and $B do not have same type, but there are in same values.
