function cmpByLength($a, $b) {
return strlen($a) > strlen($b);
}usort($arrayToSort, 'cmpByLength');
And change the '>' to '<' if the ordering is wrong.

Hey all -
I've been scouring the php.net site for a few hours now trying to find a viable way to sort a single dimensional array( array('0'=>'fddfsdsfdds', '1'=>','ddddd','2' => 'gofofle'); )..... so that the longest lengthed item is at the top, and the smallest lengthed item is at the bottom.... is there a function to do this... example:
$arrayToSort = array('0' => 'shorter_length', '1' => 'longer_than_longer_than_shorter_length', '2' => 'longer_than_shorter_length');
and I would like to get... whether the keys change or not..
$arrayToSort[0] == 'longer_than_longer_than_shorter_length'; $arrayToSort[1] == 'longer_than_shorter_length'; $arrayToSort[2] == 'shorter_length';
any ideas?
