I use intype, it is amazing! When you are coding in php you can do things like type "if" then press tab and intype inserts all this code if ( condition ) { # code... } , and selects "condition" so that you can easily edit it. You should have a look at this video to see more about the snippets. http://intype.info/screencasts/snippets/ You can get intype from here http://intype.info
Hmm. Thats decent. It would annoy me more than help me though, but to each his own - if it works for you, thats all that matters.
Obviouse Zend Studio is best for PHP, but it's too expensive... The free editor is Notepad++. Also, Scite is much good, too.
