I'll go out on a limb and assume you're looking for an application you can use to write PHP code.
I've been happily using a program called "NetBeans". I don't know if it's OK for me to link to it, but you can find it with a search on Google, Bing, etc.
It might be a little difficult to wrap your head around if you're new to programming and IDEs (integrated development environments), though.
