usort is very useful when one wants to combine or manipulate the results especially received from the db.
say for example we have an array named $displayProduct and we want to sort by the associative array call ‘order’
usort($displayProduct, function($a, $b) {return ($a['order'] < $b['order']) ? -1 : 1; });
