Hello, anny:
Welcome to PHPBuilder.com.
Many people have started learning PHP from taking online tutorials while building projects for themselves/clients at the same time. What you want to do is very basic. Very-very basic in fact. However, if you continue robbing yourself opportunities to learn by blindly copying and pasting, you will not be able to do even this basic thing that most programmers here can do in a matter of minutes.
Please do not get me wrong here: I do not mean to belittle or chastise you in any way.
My point is that YOU can do this if you take a little bit of time to learn.
AND, that is what PHPBuilder is all about: To encourage you to learn how to do things and solve PHP-related code issues yourself. PHP is a very easy scripting language to pick up and most people can grasp the syntax of the language in a week or two. (Granted there is a LOT to it, so subtleties take longer...)
So, having said that, please allow me to suggest a few great online tutorials, where, if you visit and apply yourself, you will be able to write your own script and maintain your site, should you require some changes....

I strongly encourage you to do this. For you know the old adage:
"Give a man a fish, you feed him for a day. TEACH a man to fish, you feed him for his life...."
-Hope that Helps-
