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

A little more generic solution where you can just set the key you wish to sort by and it should work for any multidimensional array.

//key to sort by
$sortBy = 'code';

$sorted = array();
foreach($routes as $route) {
  foreach($route as $key => $value) {
    if(!isset($sorted[$key])) {
      $sorted[$key] = array();
    }
    $sorted[$key][] = $value;
  }
}

array_multisort($sorted[$sortBy], SORT_ASC, $routes); 
print_r($routes)
