note 33734 added to function.array-intersect

[quote] Two elements are considered equal if and only if (string) $elem1 === (string) $elem2. In words: when the string representation is the same. [/quote] What is this? String representation of any array is "Array", and so, all arrays are equal according to this rule. Therefore the elements of the arrays cannot be arrays themselves. Say, if $array_1 and $array_2 are of the form array( array(...), array(...), array(...), ...) array_intersect($array_1, $array_2) will return same as array_merge($array_1, $array_2). ---- Manual Page -- http://www.php.net/manual/en/function.array-intersect.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+33734 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+33734&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+33734&report=yes
