php-gtk network programming

In the php manual it talks about the connection() method as being
unstable, not fully implemented and maybe temporary.  Having said all of
that, has anyone tried any network programming with php-gtk?

i was going to give it a shot and try to build a php-gtk gnutella
client, albeit a very rudimentary one.

Just thought it would be helpful to have any advice from others running
into pitfuls with such a venture.
