Perhaps from before a keyword was added for better code clarity :) Cheers, Rob. Hehe, no problem mate. By the way, does anyone know what happened to the "delete" keyword? I saw it in a Zend article before the final release of PHP 5, but i can't find it anywhere.In PHP5 to get a copy of, versus a reference to, an object the developer must call the __clone() method for the target object: $obj = new Foo(); $copyNotReference = $obj->__clone();The correct syntax for that is: $obj = new Foo; $copyNotReference = clone $obj;
