PHP Version: 4.1.2
New Comment:
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).

This error is reproducable for PHP 4.2.0rc1:
First version ($GLOBALS["obj"]=&$ref;) gives:
object(test)(0) {
}
Second version ($obj=&$ref;) gives:
NULL

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?
--- SCRIPT: START ---
<PRE><?php
class test {
function test() {
extfunc($this);
}
}
#___________________________________________________________
function extfunc(&$ref) {
global $obj;
$GLOBALS["obj"]=&$ref; # This is the same as '$obj=&$ref;'. Isn't it?
#* $obj=&$ref;
}
#===========================================================
$test=new test();
var_dump($obj);
?></PRE>
--- SCRIPT: END ---
