1.2.1412. Useless Typehint¶

__get() and __set() magic methods won’t enforce any typehint. The name of the magic property is always cast to string.

<?php

class x {
    // typehint is set and ignored
    function __set(float $name, string $value) {
        $this->$name = $value;
    }

    // typehint is set and ignored
    function __get(integer $name) {
        $this->$name = $value;
    }

    // typehint is checked by PHP 8.0 linting
    // typehint is enforced by PHP 7.x
    function __call(integer $name) {
        $this->$name = $value;
    }
}

$o = new x;
$b = array();
// Property will be called 'Array'
$o->{$b} = 2;

// type of $m is check at calling time. It must be string.
$o->{$m}();

?>

See also __set.
