$a == $b Equality TRUE if $a and $b have the same key/value pairs. $a === $b Identity TRUE if $a and $b have the same key/value pairs in the same order and of the same types. this is not a bug. $a=array(22,44); $b=array(44,22); have the same meaning as $a=array(0=>22,1=>44); $b=array(0=>44,1=>22); they don't have the same key/value pairs.
