<?php /** * Why you don't want to get in the habbit of writing things like clone($foo)... * It might take away from the insight that clone takes an expression, which means * that something like (clone $foo . 'bar') and (clone ($foo . 'bar')) result in * different operator precedences. */ class foo { public function __tostring() { return "I am a foo!"; } } $foo = new foo; var_dump(clone $foo . 'bar'); //vs. clone($foo . 'bar') which evaluate to two totally different expressions...
