When overloading a class in php, and then comparing an overloaded property to the return value of a function call, the result is not what I expected.  If comparing against string literals, or if the result of each is first assigned to a variable then it's fine.

I tested this with latest CVS of PHP 4.4.7.

Reproduce code:

class Foo {
	function __get( $name, &$value ) {
		$value = 'foo';
		return true;
overload( 'Foo' );

class Bar {
	function foo() {
		return 'bar';

$foo = new Foo();
$bar = new Bar();

echo 'Test: ' . ( $foo->bar == $bar->foo() ? 'BAD' : 'GOOD' ) . "\n";


Expected result:
Expected (meaning the comparsion failed):

Test: GOOD

Actual result:
Actual (meaning the comparsion 'foo' == 'bar' succeeded):

Test: BAD

You'll have to upgrade to PHP5.
