Returns the value at the specified key in the current Pair

public function get(
  int $key,
): mixed;

If the key is not present, null is returned. If you would rather have an exception thrown when a key is not present, then use at().


  • int $key - the key from which to retrieve the value.


  • mixed - The value at the specified key; or null if the key does not exist.


$p = Pair {'foo', -1.5};

// Print the first value

// Print the second value

// Print NULL since index 2 doesn't exist in a Pair
