Need recommendations for a good text editor.

Hello: I am new to PHP and am looking for a good text to write PHP code. I am looking for something that is user-friendly like HomeSite for Windows but capable of handling PHP code. The main features that I desire are- 1. Should run under linux. 2. Different components of the code should appear in different colors. See an example of this at http://www.phpbuilder.com/columns/bill19990831.php3?page=2 3. Automatic command completion would be nice. 4. Comprehensive PHP command library should be included. 5. This software need not be free, but reasonably priced. Thanks for your help.
