This is the only one editor that I stayed at after monther of trying others. I used PhpEdit, PhpEd, ExpertEditor, PHP Designer - none of them gave me what I had with Jedit.

Minuses about Jedit:
- slow because of written on Java
- a little bit difficult to set up everything with your needs for a newbie
- no debugger for php
- none such code completion (eg PhpEd and PhpEdit have)

Benefits:
- it free )
- perfect macros support (with macroses and bash you could do whatever you can and can't imagine)
- lots of plugins - actually these plugins a giving the most of benefits for php functionality of Jedit (like code folding, code browser, using of ctags famous for unix, code beautifiers
- supports Smarty code highlight (as good as many other languages)
- because it's on Java it's platform-independent
- perfect code screen splitting tool - you can split screen to whatever number of parts you want. this is may be the same document
- perfect searching feature - you can use regurlar expression to find and to highlight what you need
- things like FTP and database connection - feeling good here too :)

I'm using it for two days so far. Can't stop loving it.
