There is the line marked with '#*' in the following script. One line up you will find other line that should make the exactly same action (I think). Try to comment this line and uncomment line with '#*'. The output will differ. Why?


class test {
	function test() {
function extfunc(&$ref) {
global $obj;
	$GLOBALS["obj"]=&$ref; # This is the same as '$obj=&$ref;'. Isn't it?
	#* $obj=&$ref;

$test=new test();

--- SCRIPT: END ---

First version ($GLOBALS["obj"]=&$ref;) gives:

object(test)(0) {

Second version ($obj=&$ref;) gives:

Variables imported with global into the local function scope are actually references and therefore can't be assigned to another reference. $GLOBAL is a good workaround for this

However this isn't necessary for ZE2 because you don't need to pass objects by reference anymore (there's no shallowing coping going on anymore).
