I used UltraEdit and then changed to Notepad++ but decided to start using something more specific for php. I found a site that reviews quite a lot of them, PHP editors review. I downloaded PHP Eclipse (you need Eclipse and then go to Help – Software updates – Available software – Add site – oaste http://update.phpeclipse.net/update/stable/1.2.x) and will give it a try.
I was wandering what do you use (if you use) for your programming? I’m also in CSS so it would be great if it would also support this language..
