What is the best way to access unknown array elements without generating PHP notice?

Question

If I have this array,

ini_set(\'display_errors\', true);
error_reporting(E_ALL);

$arr = array(
  \'id\' => 1234,
  \'name\' => \'Jack\',
  \'email\' =         


        

Answer 1

The @ error control operator suppresses any errors generated by an expression, including invalid array keys.

$name = @$arr['city']['country']['name'];
