russrobinson, you are incorrect. Notice that in your code, line 18, you assign directly to the $var reference, which in both PHP and C++ will indeed make $var and $bar point to the same instance of the dog object. However, if you replace line 18 in your example with a reference assignment, eg $var =& new Dog("gypsy"); the example will behave exactly as described in the documentation. southerd@schroedinger:~/Desktop$ cat testRef.php <?php class Dog { var $Name; function Dog($name) { $this->Name = $name; } function GetName() { return ($this->Name); } }; $bar = new Dog("Spot"); function foo(&$var) { $var =& new Dog("Gypsy"); } foo($bar); echo $bar->GetName()."\n"; echo "If that said 'Gypsy', then object references are really pointers\n"; ?> southerd@schroedinger:~/Desktop$ php testRef.php Spot If that said 'Gypsy', then object references are really pointers ---- Server IP: 69.147.83.197 Probable Submitter: 192.234.222.10 ---- Manual Page -- http://www.php.net/manual/en/language.references.arent.php Edit -- https://master.php.net/note/edit/98761 Del: integrated -- https://master.php.net/note/delete/98761/integrated Del: useless -- https://master.php.net/note/delete/98761/useless Del: bad code -- https://master.php.net/note/delete/98761/bad+code Del: spam -- https://master.php.net/note/delete/98761/spam Del: non-english -- https://master.php.net/note/delete/98761/non-english Del: in docs -- https://master.php.net/note/delete/98761/in+docs Del: other reasons-- https://master.php.net/note/delete/98761 Reject -- https://master.php.net/note/reject/98761 Search -- https://master.php.net/manage/user-notes.php
