I use Aptana Studio for my PHP projects. I have not learned it but just used with what I was able to do in it. Many features I still don't know how to use in it.
At present, I have a HTML form and I want to write a .php script for the SEND button that it has. It is a submission script for the contact form.
I want a simple PHP IDE with which I can execute a single PHP file or work with at least two or three files easily, without much mess.
Please suggest a simple alternative to Aptana.
