Question

What is an elegant way to sort objects in PHP? I would love to accomplish something similar to this.

$sortedObjectArary = sort($unsortedObjectArray, $Object->weight); 

Basically specify the array I want to sort as well as the field I want to sort on. I looked into multidimensional array sorting and there might be something useful there, but I don’t see anything elegant or obvious.

Answer 1

Almost verbatim from the manual:

function compare_weights($a, $b) {      if($a->weight == $b->weight) {         return 0;     }      return ($a->weight < $b->weight) ? -1 : 1; }   usort($unsortedObjectArray, 'compare_weights'); 

If you want objects to be able to sort themselves, see example 3 here: http://php.net/usort
