From: [EMAIL PROTECTED] Operating system: Win2k PHP version: 4.0.4pl1 PHP Bug Type: *General Issues Bug description: $this can't be passed by reference inside of constructor the following code-snippet illustrated the problem: ----- class a { var $bla; // some intvalue var $b; // object of type b function a($i) { $this->bla = $i; // the next line ain't working in the constructor //$this->b = new b($this); } function x() { // the next line behaves like expected $this->b = new b($this); } function p() { echo "a::p ".$this->bla."<br>"; } } class b { var $a; // reference to object of type a function b(&$a) { $this->a = &$a; } function p() { echo "b::p ".$this->a->bla."<br>"; } } $a = new a(10); $a->x(); // works $a->p(); $a->b->p(); $a->bla = 11; $a->p(); $a->b->p(); ----- output: a::p 10 b::p 10 a::p 11 b::p 11 ----- this is the wanted behaviour. var $a->b contains a object of type b which contains a reference back to object $a. object b is instanciated and assigned via the $a->x() methodcall. so far, nothing special. when i want to get rid of the additional method in a (that's the x() method) and instanciate b inside of a's constructor and assign it to $a->b with $this, $a->b->a doesnt contain a reference to the calling a object but a copy of it. thus, $this isn't really working inside of an object's constructor. afaik do other languages have the same limitation of using $this inside of the constructor due to address-calculation issues. -- Edit Bug report at: http://bugs.php.net/?id=8740&edit=1 -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
