Of course you can not connect. The IDE/client must *accept* connections,
not initiate them. This is explained here:
http://xdebug.org/docs-dbgp.php#initiating-a-debugging-session . Used
terminology can be found here:
http://xdebug.org/docs-dbgp.php#terminology

Basically instead of doing a socket_connect() you'll need a
socket_listen() and wait for the webserver+php+xdebug to connect to the
client. Instead of using the socket extension I actually suggest to use
the new socket functionality in the streams part of PHP as those
functions are much more stable, for more information see:
http://no.php.net/manual/en/function.stream-socket-server.php
http://no.php.net/manual/en/function.stream-socket-accept.php
