PHP 5 Sockets Tutorial Error

Hey there, was just testing out the new php 5 socket tutorial, and well am comin up with an error when i run the bat file. It comes up with

Fatal error: Call to undefined function socket_create() in E:\Server\www\pixelBox\misc\socket\socketTut.php on line 45

Dont understand why it would do that cause i tested the socket_create on its own, and that works, which leads me to believe its a syntax error somewhere else, like a missed ; on a line, thats what usually gives me that kind of error. But ive looked through it all and it looks all fine, so any ideas?? Btw im using the code that was in zip file that was in the tutorial.
