Submitted: 2008-02-17 06:09 UTC Modified: 2008-02-21 13:57 UTC

Status: Closed Package: Class/Object related
PHP Version: 5.2.5 OS: Debian Linux

A class that is derived from a class with a private constructor and which does not provide its own constructor, can call the private parent constructor through a static function.

Reproduce code:
class X
        public $x;
        private function __construct($x)
                $this->x = $x;

class Y extends X
        static public function cheat($x)
                return new Y($x);

$y = Y::cheat(5);
echo $y->x, PHP_EOL;

Expected result:
Fatal error: Call to private X::__construct() from invalid context ...

Actual result:

I think that the parent ctor/dtor private shouldn't be called. Hence, here's a patch (5_3):

It doesn't issue error message, only isn't inherited.
