I would like to sort by rank, is there any quick sort method in PHP to do that?
You can use the usort function:
function cmp($a, $b) {
return $a['rank'] - $b['rank'];
}
$arr = /* your array */
usort($arr, "cmp");
To sort on rank in descending order (question asked in comments), you just reverse the order in the compare function:
function cmp($a, $b) {
return $b['rank'] - $a['rank'];
