array:-

array ( [0] => array ( [text] => text [count] => 0 )          [1] => array ( [text] => second text [count] => 2 )          [2] => array ( [text] => third text [count] => 1 )       ) 

i have tried following code.

try this:

note: checking equality acts added advantage.

function sort_count($a, $b) {    if ($a['count'] === $b['count']) {       return 0;    } else {        return ($a['count'] > $b['count'] ? 1:-1);    } } $sorted_array = usort($array, 'sort_count');  echo "<pre>";  print_r($array);  echo "</pre>";
