1.2.843. No get_class() With Null

It is not possible to pass explicitly null to get_class() to get the current’s class name. Since PHP 7.2, one must call get_class() without arguments to achieve that result.

<?php

class A {
  public function f() {
    // Gets the classname
    $classname = get_class();

    // Gets the classname and a warning
    $classname = get_class(null);
  }
}

$a = new A();
$a->f('get_class');

?>
