While searching for an array within another array, i.e. something like: $i = array_search(array('c','d'), array(array('a','b'), '500', array('c','d'), '2')); I got the following (with PHP Version 4.1.2): Warning: Wrong datatype for first argument in call to array_search in ... So I wrote my own array search, like: function another_array_search($needle, $haystack, $strict = 0) { foreach ($haystack as $key => $value) { if ($strict) { if ($needle === $value) $match = $key; } else { if ($needle == $value) $match = $key; } } return $match; } (I tried to make it behave like the original function in PHP Version 4.1.2) and now this works fine: $i = another_array_search(array('c','d'), array(array('a','b'), '500', array('c','d'), '2')); echo $i; and it displays "2". I hope it helps anyone. -- http://www.php.net/manual/en/function.array-search.php http://master.php.net/manage/user-notes.php?action=edit+30632 http://master.php.net/manage/user-notes.php?action=delete+30632 http://master.php.net/manage/user-notes.php?action=reject+30632
