note 93812 added to language.references

Note that in PHP5 you generally don't need the reference operator -- at all -- when dealing with class objects, because PHP5 implements objects using Instances (which are more like C pointers than PHP's references system). For example: <?php // // Since PHP 5 // $foo = new stdClass(); // $bar and $foo are still holding the same (single) object $bar = $foo; var_dump($foo, $bar) // object(stdClass)#1 (0) { } // object(stdClass)#1 (0) { } $bar->member = "Something"; var_dump($foo, $bar); // object(stdClass)#1 (1) { // ["member"]=> // string(9) "Something" // } // object(stdClass)#1 (1) { // ["member"]=> // string(9) "Something" // } // Use the 'clone' keyword to make a separate copy of the object $bar = clone $foo; $bar->member = "Something"; var_dump($foo, $bar); // object(stdClass)#1 (0) { } // object(stdClass)#2 (1) { // ["member"]=> // string(9) "Something" // } ?> ---- Server IP: 208.69.120.35 Probable Submitter: 67.237.228.46 ---- Manual Page -- http://www.php.net/manual/en/language.references.php Edit -- https://master.php.net/note/edit/93812 Del: integrated -- https://master.php.net/note/delete/93812/integrated Del: useless -- https://master.php.net/note/delete/93812/useless Del: bad code -- https://master.php.net/note/delete/93812/bad+code Del: spam -- https://master.php.net/note/delete/93812/spam Del: non-english -- https://master.php.net/note/delete/93812/non-english Del: in docs -- https://master.php.net/note/delete/93812/in+docs Del: other reasons-- https://master.php.net/note/delete/93812 Reject -- https://master.php.net/note/reject/93812 Search -- https://master.php.net/manage/user-notes.php
