You can use the socket functions in conjunction with TCP wrappers.

For example, take a look at fsockopen() in the manual:

http://ca.php.net/fsockopen

The resulting resource can be used with fwrite() and fread() and the likes
as if it were a file resource.

For more complex applications, you can use the actual socket API:

http://beeblex.com/manual/ref.sockets.html?s=man%3Asocket

Finally (since you mention you're connecting to a .Net app), maybe what you
need is a web service protocol like SOAP, in which case if you're using PHP
5 there is a built-in extension, whereas PHP 4 requires you to use a
userland library like the one provided by PEAR:

Cheers,
