# Returning values

Values are returned by using the optional return statement. Any type may be returned, including lists and objects.

    function square ($num) {
        return $num * $num;
    }
    echo square (4);   // outputs '16'.

You can't return multiple values from a function, but similar results can be obtained by returning a list.

    function small_numbers() {
       return array (0, 1, 2);
    }
    list ($zero, $one, $two) = small_numbers();
