I'm wondering why nobody has mentioned Zend Studio. It's been years last time I touched PHP code, but I used this IDE and it was almost like being in Visual Studio (minus the Visual part of course). I'm sure it has come a long way since then.

Looks quite expensive to me at $299 for a year (or $617 for 3 years) with updates and then the same again every year (or 3) if you want to keep updating as things change. OK there is a perpetual license to use the software but it would be nicer to have a reasonable purchase charge and then a smaller annual service charge.

I stumbled upon a list of Code Beautifiers and Formatters at Smashing Magazine. It is quite extensive and has screenies.

That page has found me two types of sites that I have been looking for for ages. Thank you.

I've been trying to find a way to print code in colour easily and http://quickhighlighter.com/code-syntax-highlighter.php +  'Firefox: Print selection' is it.
