Notepad ++ is great and works on a multitude of platforms.Originally Posted by djdykes
I use HTML-Kit but it's syntax highlighting is not extensible and modifiable except for a few colors. There are all sorts of plugins for HTML-Kit including a PHP kit that provides a toolbar with all sorts of code segments. In addition you can do snippets and in browser uploads with HTML-Kit as well.
I used to use Dreamweaver and found that by MX 2004 it uses so much system resources that it is almost silly for editing HTML and other languages. I can do all my editing on my PIII 600 if I have to without any issue with HTML-Kit or Notepad.
Line numbers tabs and syntax highlighting are the most important parts when getting into PHP (for me).
