Can anyone help me out here.

I want to make a global variable, and then make it reference to the newly instantiated class.

Heres the code:

<?php

class test {

	var $txt = '1';

	function test() {
		$GLOBALS['test2'] = & $this;
	}
	
	function disp($n) {
		echo $n.':'.$this->txt.'<br />';
	}
	
}

$test1 = new test();

$test1->disp('test1'); 	// OUTPUT: test1:1
$test2->disp('test2'); 	// OUTPUT: test2:1

$test2->txt = '2';

echo '<br />';

$test1->disp('test1'); 	// OUTPUT: test1:1
$test2->disp('test2'); 	// OUTPUT: test2:2
								// ^ Why aren't they the same :'(
?>

As you can see on the last few lines, the outputs are not the same....
So the reference must of created another copy of the class.... When i want it to refer to the first copy of the class.

Cheers.

EDIT:
As it is a plugin should something like this be used instead?

	function AppendPluginRegister ( & $params )
	{	// Add a global reference to this class
	
		if( $this->ID > -1 && !isset( $GLOBALS['common_imports_plugin'] ) )
			$GLOBALS['common_imports_plugin'] = & $GLOBALS['Plugins']->get_by_ID( $this->ID );
		
		return true;
	}
