A few off the top 'o me head:Aptana StudioNotepad++Crimson EditorText-wranglerNetBeansKompoZerKomodo edit
Try several features of NetBeans, like coding time typing hints.And the best of all, remind of the @todo lines within the multi-lined comments.
PHPEdit is also a good replacement.But dreamweaver gives good design mode.
There are many editors available which can be alternative for Dreamweaver. You can select them from below..
I heard good things about NVU but have no experience with it.
Tried nvu, small, no installer, ...Interface looks like a variant of eclipse, which is probably not.
