I add my vote to phpEd!! The address describing it: [url=http://www.nusphere.com/products/php_ide_major_features.htm]http://www.nusphere.com/products/php_ide_major_features.htm[/url] and it is actually one of the best IDE's I have tried, for any language, no kidding. It is intuitive, doesn't get in your way, can custom color highlight different kinds of code in different schemes in the same document, has very smart code completion for PHP that is smart enough to be able to show you your own classes functions and variables as choices, an AMAZING debugger that can even debug live applications and follow through after a submission on a form and keep debugging, a database client that is really intuitive and quick that lets you do cool things like drag and drop fields on your form. You really have to try the free trial version to believe how nice it is. There are videos on the web site showing the product in use, and I have been amazed to find it really is all they advertise and more. 8)
