The great big change we’ve all been waiting for. I in fact refuse to take the Zend exam until it’s PHP5ied because right now it would confuse the hell out of me.

In PHP4, which Stoyan is referring to, a RESOURCE is passed by reference while anything else is passed by value. Try replacing the imagecreate line by $image = “foo”; and the imagedestroy line by unset($image); The copy will still result in a string in the var_dum($copy); line, indicating pass by value.
