Zend just recently released a beta version of Zend studio 4.0. It boasts of Database support, Improved PHPDoc and PHPDocumentor support, a code snippet library, and few other things. If they finally recognize the clone keyword then I’ll be happy 
. In any case I went ahead and downloaded it and will be doing a pretty thorough evaluation of it be the end of the week. Stay tuned and you can see my opinion. (For what it’s worth)
Oh, and here’s a link to it: http://www.zend.com/store/products/zend-studio/beta.php
