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

That's what array_multisort if for:

foreach ($routes as $key => $row) {
    $code[$key]  = $row['code'];
    $name[$key] = $row['name'];
}
array_multisort($code, SORT_ASC, $name, SORT_ASC, $routes);

print_r( $routes );

That way you don't even need a second array!

In fact in your case you need only to sort the codes so this will do the trick:

foreach ($routes as $key => $row) {
    $code[$key]  = $row['code'];
}

array_multisort($code, SORT_ASC, $routes);
