note 31934 added to function.array-merge

WARNING: The + operator between arrays is NOT commutative! If $arr1 and $arr2 share some identical keys (with different associated values) then $arr1 + $arr2 won't be the same as $arr2 + $arr1. This is unsane! Normally, the + operator should always be associated with a commutative operation... -- http://www.php.net/manual/en/function.array-merge.php http://master.php.net/manage/user-notes.php?action=edit+31934 http://master.php.net/manage/user-notes.php?action=delete+31934 http://master.php.net/manage/user-notes.php?action=reject+31934
