This would be why I thought it was by design. That works for me. I just
changed the $new = new TestClass2(); to $new = new ::TestClass2(); and
it worked perfectly. Thanks.

Thanks to Marcus who brought light into this:

You access classes from the global namespace by ommiting the
namespace-name part:

new ::TestClass2();

is the proper syntax. Same for my exception extending problem:

php -r 'namespace myscope { class myexception extends ::exception { }
}'

Marking as a documentation problem (it's not in ZEND_CHANGES even).

Also pretty annoying if you want to declare a class extending the main
exception class in your namespace. It simply doesn't work because its
not "seen":

$ php -r 'class myexception extends exception { } '
[no error, works]

$ php -r 'namespace myscope { class myexception extends exception { }
}'
Command line code(1) : Fatal error - Class 'exception' not found

I couldn't find a way to reference the global namespace.

If I have the following script, the class that is defined before the
namespace cannot be called from within a class in the namespace.

<?php
class TestClass2
{
    function __construct()
    {
        print "TestClass2\n";
    }
}

namespace Test
{
    function newClass () {
        $new = new TestClass();
        $new->newClass();
    }
    
    class TestClass
    {
        function __construct()
        {
            print "TestClass\n";
        }
        
        function newClass ()
        {
            $new = new TestClass2();
        }
    }
}

Test::newClass();
//$new = new TestClass2();
?>

This example will show the error "Fatal error: Class 'testclass2' not
found in c:\usr\test.php on line 26" I'm assuming that this is done by
design... but I would think that PHP would look for the class outside
of the namespace since it is defined before the namespace. If you use
the commented out line $new = new TestClass2; instead of the
Test::newClass(); then it works properly, and the TestClass2 construct
is called.

As I said, I think this is done by design and isn't a bug... but I
thought I would submit it because I'm not for sure. Any explination
though would be very helpful to me. Thanks.
