I would recommend getting used to vim, very powerful and useful editor but its quite a handful to get used to. Like the previous post said, its good for fluent and quick development as everything is controlled via the keyboard (well gVim uses the mouse for certain things to keep the non terminal people happy).

My best choice for IDE would be PDT: http://www.zend.com/en/community/pdt
or if your willing to shell out some cash: http://www.zend.com/en/products/studio/

Or there is a visual studio version for PHP

My best advice is just to download and test loads, it took me ages to find an environment that I liked.
