Doing A Deal If you've been working with PHP for a while, you're probably used to thinking about it only in the context of a Web page or a Web server. While this is not unusual - PHP is, after all, a scripting language that's most commonly used to dynamically generate Web pages - it can stifle your creativity; as you'll see in this article, there's a lot more you can do with PHP than just connect to a database, retrieve records and insert them into an HTML template.
One of PHP's better-guarded secrets - and one that I discovered quite by accident - is a very comprehensive set of network programming functions. Steadily evolving over the last few releases, this socket programming API now supports almost everything you would need for socket-based client-server communication over TCP/IP, and can be rapidly deployed to build simple client-server applications in PHP.

So, maybe these tips can help you out: Use heredoc syntax for strings: If there's one thing I got tired of fast, it was building long strings like this: If I am going to make a string with more than one line, and even sometimes when I'm not, then I use heredoc.
