Assigning values in PHP

Sample of assigning values to variables and doing some strange operations.

<?php
	function outputme($_x, $_y) {
		echo "( $_x, $_y )<br>";
	}

	$x = 5;
	$y = 3;
	outputme($x,$y);
	$x += 2 * $y;
	outputme($x,$y);
	$x += ($y *= 2);
	outputme($x,$y);

?>

OUTPUT:

( 5, 3 )
( 11, 3 )
( 17, 6 )
