Sorting multidimensional array based on the order of plain array

Question

I have this array:

  $routes = array(
  array(
     \'code\' => \'PZSA\',
     \'name\' => \'PLaza san antonio\',
  ),
  array(
     \'code\' => \'AVAD\         


        

Answer 1

$target_flip = array_flip($target);

usort($routes, function($a, $b) use ($target_flip){
    return ($target_flip[$a['code']] < $target_flip[$b['code']]) ? -1 : 1;
});
