Edit report at https://bugs.php.net/bug.php?id=74862&edit=1 ID: 74862 Updated by: nikic@php.net Reported by: daniel at ciokix dot ro Summary: Unable to clone instance when private __clone defined -Status: Open +Status: Verified Type: Bug Package: Scripting Engine problem Operating System: Ubuntu 14.04 -PHP Version: 5.6.30 +PHP Version: 7.0.24 Block user comment: N Private report: N Previous Comments: ------------------------------------------------------------------------ [2017-07-06 06:36:17] spam2 at rhsoft dot net the only probably bug here is that you don't get a error message that you can't set arbitrary magic methods as private like you get it for __construct() and __get() but given that PHP5 is EOL I won't expect that to change ------------------------------------------------------------------------ [2017-07-06 04:23:13] daniel at ciokix dot ro Description: ------------ When defining the __clone magic method as private, the instance cannot be cloned from within the method implementing parent class. Test script: --------------- class a { private function __clone() { } private function __construct() { } public static function getInstance() { return new static(); } public function cloneIt() { $a = clone $this; return $a; } } class c extends a { } // private constructor $d = c::getInstance(); // private clone $e = $d->cloneIt(); Link to 3v4l: https://3v4l.org/bWr72 Expected result: ---------------- Expecting the same behavior as for __construct: a successfully cloned object. Actual result: -------------- The following misleading fatal error is thrown: Fatal error: Uncaught Error: Call to private c::__clone() from context 'a' which is not the case as clone is called from a context and not c. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74862&edit=1
