Sorting an array based on its value

Question

I have an Array, Sample:

$array {
 [0] {
   [something]=1;
   [something2]=2;
     } 
 [1] {
   [something]=2;
   [something2]=4;
     }
 [2] {
   [somethin         


        

Answer 1

function compare($x, $y) {
    return $x['something'] - $y['something'];
}

usort($input_array, 'compare');

you need to use a usort() similar to the above.
