Rightly or wrongly I have always used notepad to develop my PHP applications. I have always found it very quick and easy to use BUT I know there are so many programs out there specifically designed for developing PHP apps.
I was wondering if those of you who use editors specifically for PHP could tell me what I am missing and perhaps suggest some good alternatives. I am particularly interested in features such as syntax highlighting for instance.
I'd really like to hear peoples thoughts on the subject.
