PHP studio is a text editor specifically designed for editing PHP code. I can’t say that I’ve ever used it personally, but looking over the information on the site, it seems like it has features for both seasoned pros and newbies alike.
For the next 8 hours you can get PHP Studio for $5 over at MacZot. It’s normally $25.
Being a PHP newbie myself, I went ahead and bought it. I figured $5 is a pretty small investment if it helps me learn and edit my php files, like the ones used in this blog.
