PHP Bug Type: Scripting Engine problem
Bug description: Overload Comparison Problem
Description:
------------
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
