So sorry if this question is really obvious but.... I've done a lot of objective c programming on iphone and mac but I want to learn some other languages, specifically web languages. I already know some basic HTML and I'm following a tutorial on PHP. I'm using Komodo Edit to type up my PHP script. But I save my hello world script as a php file but I don't know how to run it. When I double click on the file it tries to open it up in dreamweaver but then asks for a serial number. I didn't even know I had dreamweaver on my mac and I don't have a serial number for it. Is there a way to have Komodo edit run the script? If not, what's the best way to execute it? Thanks in advance.
