You make it sound easy. I have been at php.net. There are a number of actions you must take before you can actually begin programming in php.
You have to download a php program. Then you have to fiddle around with mySQL, etc.
I don't think its that difficult but there are a number of 'things' you have to do first.
I still have to figure out what those things are first.
And I have to practice as well
