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

Rather than doing what is essentially a linear search for each element, it might be quickest to re-index your original array by code:

// create the index
$indexed = array();
foreach($routes as $route) {
    $indexed[$route['code']] = $route;
}

// add each target to a new sorted array in order
$sorted = array();
foreach($target as $code) {
    $sorted[] = $indexed[$code];
}
