What values were you expecting?

PHP Code:


			
$GLOBALS['yetanothertest'] =& $test;

Assigns the global variable by to reference to the local variable to test; it's not affecting $yetanothertest in the local scope of the function.

and

PHP Code:


			
$anothertest =& $test;

Is only affecting the reference of the local variable $anothertest...$anothertest does not have scope after the function call, however, if you assigned a value to the variables as you mentioned...it will affect all the variables that reference that data.

I know I'm not explaining it that well, there's a section in the PHP manual dedicated to explaining references over at php.net.
