Socket Tutorial

I did the PHP socket tutorial on this website. I just cannot get it to work. I am on a paid host and still nothing. I have been working at getting just something running for 3 days but this makes absolutely no sense. I have some PHP knowledge and can script entire web based shopping cart software etc…but this is another story. I don’t know what I am doing and I can’t seem to get anything to work locally or online. What should I do? Does Flash MX not have the same socket capabilities of Flash 8 because I am running Flash MX. Please let me know something! Thanks guys.
