Hey I'm starting a 6 months internship as a PHP developer. What IDE/Editor would you recommend I use? For the past 4 days I've been using Eclipse PDT. Any notable advantage using Vi, emacs, Jedit, ... ? I guess my question is: what IDE do you use for web develoment?

PS As usual, I'm using Ubuntu, so I'm only interested in linux-based ...
I don't know if it's available for Ubuntu, while I was using PDT, some colleagues were using Zend Editor. Worth checking if you can get a hold of it.
For all purposes, PDT will serve you very well.
I usually use Netbeans with php plugin, I think it is good for Php at least for what I do and of course is available on Linux. And as Arithma said, the Zend Editor can be a good choice too but I am not sure if there is a version for Linux. Good luck :)
Zend exits but you have to buiy a license. I'm sticking with Eclipse for now, but will probably try Netbeans at some point.
I tried both Zend and uh Eclipse. I couldnt easily get the debugging to work in either, so i reverted to non-assisted debugging (print_r and stuff) with a simple code editor (Smultron or Textwrangler on osx, Emeditor on PC).
NuSphere supposedly has a good (the best?) php IDE, but I think it only runs on PC. I guess you could check Zend too.
Also take a look at xdebug.org
(PS: if Eclipse works for you, stick to it. Stick to whatever works.)
Also available and interesting:
"Delphi for PHP"
Thanks rolf, I'll check those out. Eclipse works fine yeah, but still I haven't really tried anything else, so ...

Anyone recommend the use of a simple editor over an IDE?

If you are working on small stuff, a simple editor with syntax highlighting would be enough, I usually use Notepad++, light and useful editor supporting a variety of languages, also Programmer's Notepad is nice too, on Linux I would use Scintilla which is also available for Windows :)

If you want to use an IDE then go for Adobe Dreamweaver CS4 or something. But if you're looking for something light and effective I recommend jEdit. I started using it like 3 months ago and I'm really happy with it. You can customize the syntax highlighting to your liking and do some really interesting stuff with it. But there is no code hinting or anything like that. I also have Notepad++ but jEdit is just fine for me.

P.S: I've heard from alot of PHP developers that Eclipse and Zend are really good too.
Notepad++ is quite good but unfortunately it crashes for no obvious reasons here and there. To the point I went back at times to EditPlus - didn't go PDT due to the amount of time it requires to install.
After two weeks, I'm moving away from PDT. Way too heavy, frequent crashes, I need something fast and simple. I am downloading Netbeans right now. Let's see how it goes.
