  'v1',		// $arr[0] == 'v1'
  'v2',		// $arr[1] == 'v2'
  'v3'		// $arr[2] == 'v3'
);
// or (since PHP 5.4)
$arr = [
  'v1',		// $arr[0] == 'v1'
  'v2',		// $arr[1] == 'v2'
  'v3'		// $arr[2] == 'v3'
];

// key accessed array (map like)
$arr = array(
  'k1' => 'v1',		// $arr['k1'] == 'v1'
  'k2' => 'v2',		// $arr['k2'] == 'v2'
  'k3' => 'v3'		// $arr['k3'] == 'v3'
