Question

I want to access information in an associative array by index like so

$arr = Array(
    ['mgm19'] => Array(
        ['override'] => 1
    )
);

$override1 = $arr['mgm19']['override'];
$override2 = $arr[0]['override'];

but i get nothing from override2 why ?

Answer 1

Because $arr has only one index, mgm19. Nothing is associated to the index 0. If you don’t know the index or don’t want to use it, use foreach:

  foreach($arr as $value) {
     echo $value['override'];
     break; /* breaking so that we only read the first value of the array */
  }
