This tutorial aims to raise your skills and clear up any confusion or questions you have regarding socket programming with PHP. Let's first talk about what a socket is. Take a look at the picture below...it's a normal to think of these when you hear the work "sockets". Conceptually we can use these socket tools to get a clearer picture of just what sockets do. A socket is a plug or a way to connect to another computer. This computer might be in the next room or across the world which is known as network programming. Your computer is assigned an IP address. This IP address let's any computer in the world know where to reach you (Let's pretend for a minute that firewalls don't exist and you're connected directly to the internet) Computers communicate with your computer through "PORTS". This allows around 65,000+ different applications to be talking to the internet at any given time. If you didn't have ports, computers would have a hard time trying to find out what data was meant for what program.

Over this second article in a series covering network programming in PHP, you will learn how to run popular Windows network monitoring utilities, such as the “ping,” “netstat” and “ipconfig” programs, by adding some new methods to the “QueryProcessor” class introduced in the previous article.
Working with low-level sockets can be a painful task in PHP. Fortunately, PHP offers a nice library of socket handling functions to make your life easier. If you do a lot of network programming in PHP, you will want to check out this three-part series, which starts with the basics and takes you through more advanced approaches. This article is the first one in the series.
Welcome to the first of three tutorials in a series that covers network programming in PHP. In this article you will learn how to use some useful PHP networking functions that will help you perform a variety of common networking tasks. To that end, you will build a simple networking query application in PHP 5.
Sockets are a method in which PHP can connect to another server over the Internet and networks. The basic function to open a socket to a server is fsockopen(). You may be wondering why you would want to connect to another server? If you need to obtain information from a 3rd party server then sockets are for you.
This tutorial is intended for the PHP programmer interested in exploring the use of PHP Sockets functions to create an Internet Socket Server.
