What editor do you use for php? (Page 1 of 5)

I use Ultraedit. It is, in my opinion, the most complete text editor for Windows. It's a bit expensive though. I've been looking for a free replacement, but I have to find anything that can match Ultraedit.

I'm extremely happy with Kate. It's Linux/KDE only though so I don't know if this is a big help for you.
It does dynamic line wrapping without destroying the indentation!
It has grat network  support, if you have ftp/ssh access you can open/save on remote machines. Along with the bookmarking system this makes life a lot easier if you have many sites to maintain.
It does mixed syntax highlighting for PHP/HTML as well, it has word completion (handy when you keep forgetting the name of that function you ust wrote.. )
For mouse junkies it has good drag&drop support as well.
It's pretty much like Ultraedit without the fee.
I believe it comes with most Linux live CDs featuring KDE so you can give it a try.

What I don't like is that they're both very expensive.
Zend Studio is good though, I like the PHP function browser.
Dreamweaver has limits when you start separating your code from the HTML in a strict manner.

I can't say I'm much of a PHP programmer (or programmer at all, for that matter), but I do my coding in SciTE. It's available for both Windows and Linux, and like Notepad++ it's based upon Scintilla.

zend studio

TextMate on OS X.

Notepad 2 is what I use.  It's also FREE. 

Edit Pad Pro.

Edit: Thought some one might like a screenie of it: http://www.upit.be/uploads/images/epp7782.png

Thats my own syntax coloring scheme, the default has a white background, and i find when coding for several hours the white background starts to hurt my eyes

Also i found when i tried it on linux, the linux port for it was not as good as the windows version. On linux i generally end up using nano (You can turn syntax highlighting on for it )

Bluefish http://bluefish.openoffice.nl/index.html
It runs on everything but Windows. (I'm running it on Linux, Debian Sid / Kanotix)

ok guys here is a free software for editing php..
php designer 2005
http://www.mpsoftware.dk/

I used that quite a bit until I switched to Eclipse, that has (or at least had) better auto completion (also for variables you've made and such, not only the stock php functions)

Thanks all for the comments. I will look in the Linux-compatible options next time I do some punbb hacking. But I'm not sure I can part with the emacs keybindings that are hardwired into my brain.

To Ruckus: that is indeed an "interesting" color scheme you have in Edit Pad Pro. Deep blue on a black background, your eyes must be genetically modified if you find that relaxing to the eye. But I also see that you use long lines and therefore need horizontal scrolling, something I find incredibly annoying. Sometimes I do "view source" on a web page to see how the designer did something and that's not easy if it is in a couple of 2000-character long lines. I personally also find automatic word wrapping like in wordprocessors (I rarely use them) to be mildly annoying when I am copyediting a paragraph and my mental map of where the things are in the paragraph that need work needs constant adjustment because I added a few words to the beginning of the paragraph.

The problem for me is that I don't like either alternative. Either the lines are cut off (impossible to read how the code works) or the lines are folded around (hard to read unless the line wrapping is really smart, and in any case for me unpleasant to modify).

It's a matter of taste I guess.
