PHP can't connect to localhost XMPP server on port 5222

Question

I've set up an ejabberd install locally on my Windows box, where I also have Apache, PHP and MySQL. I've also confirmed that it works great using Digsby, and have kicked the tires a bit by creating some users, sending some messages, etc. All good.

However, PHP can't open a stream using stream_socket_client to port 5222. Even at its simplest level:

stream_socket_client("tcp://localhost:5222", $errno, $errstr, 30, STREAM_CLIENT_CONNECT);

Returns a timeout error. However, again, connecting with an IM client to localhost on port 5222 works fine. (Using stream_socket_client to open a simple connection to localhost on port 80 also works.)

Any ideas? I'm stuck!

Sometimes you just need to peek on the line to see exactly what is going on. Windump(tcpdump) is your friend in these cases.
