when i remove $_GET

Oh boy. $_GET is global array containing all data passed in url, like:
http://foo.bar?foo=bar&foobar=bar%20foo
Then you have

Quote:

array( 'foo' => 'bar', 'foobar' => 'bar foo', );

So, if you see that index is undefined it means you have to pass the parameter via url, like:

http://localhost/script.php?ip=127.0.0.1&port=7777
