What Development Environment do you use?

So I'm about to begin working on a largish php, mysql, ajax based site and I want to hear what development environment everyone else is using for php development and what they recommend.

For what little php I've done so far I've used visual studio cause I'm an old school c++ guy, but it basically sucks for php. So anyone got any tips on what environments I should try? Especially if theres something with autocomplete and intellisense for php, but maybe i'm asking too much

 

for php I use phpedit
for mysql I use mysqlfront

Zend Studio or Eclipse

 

Zend Studio

 

DreamWeaver

 

I second krt... Zend is great, but if you don't want to spend money on your IDE you will be fine with Eclipse

 

I use Zend Studio, Mysql Admin/Query Browser/Command line and Subversion for developing web applications.

 

I use a plain IDE. e-texteditor
