Bug description: Type-Hinting with namespaces does not work
Description:
------------
Using a type-hint with a namespace does not work. It allows an object of
a different class to be passed, and even allows a bogus namespace to be
used. It will also allow null variables, and will pass through any value,
no matter what class type-hinting you use.
Unfortunately, in my simplest test cases I have not been able to reproduce
it, it is only in my larger project that it causes this problem.
I really don't know where to start with this, and how to duplicate it.
Needless to say, have provided the failing code from my project. The
entire project is several thousand lines of code. And I've really done my
best to track down the problem, even using the 5.3-alpha3-dev.
I'll include the code that causes the problem.
I really don't know what's wrong, and why it is doing it. Any hints as to
what I might be able to do to try to reproduce this in a simpler way would
be nice, but I really don't know where to go from here.
Reproduce code:
---------------
<?php
namespace MyNamespace;
class MyClass
{
// execute
public function execute()
{
$this->test(NULL);
return $this->_execute($this->_mc);
}
protected function test(MyBogusNamespace::MyBogusClass $m)
{
$reflect = new ReflectionClass(get_class($this));
$method = $reflect->getMethod('test');
echo $method;
var_export($m);
echo "\n\nClass: " . get_class($m) . " ==
MyBogusNamespace::MyBogusClass\n\n";
}
}
?>
Expected result:
----------------
Catchable fatal error: Argument 1 passed to MyNamespace::MyClass::test()
must be an instance of MyBogusNamespace::MyBogusClass, null given, called
in /srv/www/test/ns/new.php on line 9 and defined in
/srv/www/test/ns/new.php on line 13
Actual result:
--------------
Method [ <user> protected method test ] {
@@ /srv/spin/spin4/spinnaker/extender/universal/tablelibrary.php 73 -
80
- Parameters [1] {
Parameter #0 [ <required> MyBogusNamespace::MyBogusClass $m ]
}
}
NULL
== MyBogusNamespace::MyBogusClass
