Previous Comments: ------------------------------------------------------------------------ [2011-07-01 11:54:49] qq541921209 at gmail dot com 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. Is that a bugs? I need help with this. Test script: --------------- <?php $A=4; $B = '4' - '0'; echo '$A === $B '; echo $A === $B?"true":"false"; //Out put $A === $B true ?> Expected result: ---------------- $A === $B true ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55106&edit=1
