This function provides a way to sort an array by string length.

<?php

$array = array('0'=>'x', '1'=>'xx', '2'=>'xxx');

usort($array, "strlensort");

echo '<pre>';
print_r($array);
echo '</pre>';


function strlensort($a, $b) {
        if (strlen($a) == strlen($b)) {
              return 0;
        }
        return (strlen($a) > strlen($b)) ? -1 : 1;
}

?>
