I've had to switch to a windows 7 laptop, so my old Zend studio 5.5 won't work on it. Despite reading online as to how to get it working, it makes no sense to me and I don't have the time to spend half a day breaking windows to try and see if it'll work.
I've been using the trial of Zend studio 9.1 however it's slow, completely different and I can't find a PDF on their site that I'd found a few months back which explained how to 'transfer' your way of work over from 5.5 to 9, and one of the major reasons that I use Zend, the realtime error detection, isn't running and I can't find a way to enable it.
I've also tried Aptana studio, which is free and opensource but it's buggy and now won't even open.
So, I'm after recommendations for a new editor to try. I'm not necessarily after a freebie, I happily paid for Zend Studio. I just want a few simple features to make working quicker/easier/more efficient
1. real time error detection - probably the most important. It saves a lot of time.
2. PHP code hints - not so important as I do spend half the day on PHP.net anyway, but it can help when you're not sure if there's an underscore in a function or not. Again, a nice time saver.
3. Project set up / management
4. If there's project settings, then ideally the project should link files together eg. in ZDE I could control + click a function name and it would open the file and jump to where the function was.
5. syntax colouring - probably standard these days but figured I'd drop it in.
The first feature is the most important and is really a requirement. The others would just be extremely useful, although point 2 I could lose if I had to.
Recommendations welcome, and no I don't want to use Notepad. Not knocking it, but I need software that'll help me work more efficiently
