Re: Pass source object to clone like __clone($origThis)

The goal is to be able to access the original object and it's id/hash. Usecases: - something is associated with the object using the object id/hash and it needs to be cloned as well we need the original object to obtain it's id/hash for spl_object_id and spl_object_hash methods - bounded Closures ar associated with the original object and they needs to be rebound to the cloned object example: public function __clone(self $origThis) { if ((new \ReflectionFunction($this->fx))->getClosureThis() === $origThis) {

       $this->fx = \Closure::bind($this->fx, $this);

} } Modification of php is simple: https://github.com/php/php-src/pull/6063/files#diff-beea8c5a8ceb318220b34b73e4ecfc98R252 we simply pass the old object as 1 parameter. I belive, passing old object have positives and no performance nor compatibility impact. All other current solutions require an extra property and a lot of code, as assigning in constructor is not enough (due serialization etc.), or it is even impossible, if object was created using reflection without constructor.

Now I rethinked about what I said. Really, maybe clone is not the best option. So maybe we can just use a method that will clone and will have access to both informations. But I don't know if it solves the original message. public function getUserCopy() { $userCopy = clone $this; $this->copies[] = $userCopy; return $userCopy; }

If your goal is to track copies, then a static makes much more sense. class AllKnowing { private static $copies = []; public function __construct(...) { self::$copies[] = $this; .... } public function __clone() { self::$copies[] = $this; } } -Sara
