Re: sorting associative array

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Use usort (stealing from php docs):



function cmp($a['score'], $b['score'])
{
   if ($a['score'] == $b['score']) {
       return 0;
   }
   return ($a['score'] < $b['score']) ? -1 : 1;
}

$data = array(...);

usort($data, "cmp");
