if you are looking for html editors and other tools, a good place to find those is here Useful Web Tools - The Best Web Tools Reviewed. Hope it helps! I have a fun time reading this site.

I use Codelobster PHP Edition.
It is free and fast PHP IDE with support of various frameworks.

the support of various frameworks is however not free......
not a problem if the codes being professionally developed then there has to be some revenue somewhere to pay for that development cost

and its higlhy likely that user clod is either the author or connected to the authors of codelobster

if i do use Editors it's vi or gedit - or textwrangler on OS X

But: I rarely use standalone Editors. Especially when connecting Databases you often have a bunc of files. So i do use an IDE and group those files to projects. IMHO the best IDE for PHP is Netbeans 7.x !

Good Editor, brilliant Code Completion ( works for Filenames in Project too), Good hints and Error-Listings for HTML,CSS,Javascript, PHP and SQL. Integrates and works with Xdebug, PHPUnit and a lot more. I have seen some IDEs ( up to PDT PHPEclipse or PHPStorm and so on) but i really prefer using Netbeans.

i Just open up a empty Subversion Repository check it out as a new Project, tell Netbeans wich Folder of the Project is to contain my Sources and where to mirror them to a local or remote Apache and start working and i rarely have to leave the IDE.

I use dreamweaver probably because it was quite easy & flexible when i've started using it.
