Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php This is expected behavior. Please see bug #55475 for more info. ------------------------------------------------------------------------ [2012-03-29 02:37:04] yohgaki@php.net The same behavior in PHP 5.4.1RC. Is this a doc problem or bug in PHP? From http://php.net/manual/en/function.is-subclass-of.php ---- allow_string Whether to call autoloader if the class doesn't exist. ---- ---- 5.3.9 Added allow_string parameter 5.0.3 You may also specify the object parameter as a string (the name of the class) ---- I'm not sure, but is this a bug introduced by is_a() fix? I didn't follow the discussion, so I hope someone could address this issue. BTW, correct PoC would be following code. <?php class Super {} class Sub extends Super {} var_dump(is_subclass_of('Sub', 'Super')); // true var_dump(is_subclass_of('Sub', 'Super', true)); // true var_dump(is_subclass_of('Sub', 'Super', false)); // false ?> ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
