I recently discovered PHP Designer 2006 Beta and I really like it. Not designed so much for C++. It's mainly for PHP, HTML, XML, MySQL, and other scripting languages. There is a bar at the top allowing you to select which language you want to be highlighted and it will make all portions of that language within the current file highlighted. Very useful if your files consist of lots of intertwining HTML, PHP, and MySQL queries, as you can make parts of your files stand out when you are developing them. I haven't messed with any of the features yet but there are alot of them.

I've also been an avid user of Textpad for years.
