Socket Programming With PHP - Game Over

(Page 9 of 9 )

And that's about all I have time for. In this article, you learned a little bit about PHP's socket programming functions, using them to create and manipulate socket connections in a networked environment. In addition to some simple examples, you also learned how to apply PHP's socket API to real-life situations with practical examples, including a POP3 client and an authentication server.

The latest version of PHP, PHP 4.1.0, comes with an updated socket API, one which offers developers greater control over socket creation and closely mimics the socket API used by programming languages like C and C++. As of this writing, many of these new functions have not yet been documented in the PHP manual; however, if you're familiar with socket programming in C, you should have no trouble adapting your code to use these new functions.

You can read up on PHP's socket functions at http://www.php.net/manual/en/ref.sockets.php
