Does anyone know of any online editors suitable for editing PHP (i.e. web-based code editors, that either use a textarea, or fill the entire page) that have line numbers and syntax coloring? Those are really the only requirements I have.
Preferably free, if possible. I've found a few, but they're either really buggy, or really expensive. Am curious to see if anyone has run across anything that they thought was impressive...
I've spent the last half day on google; am hoping that someone has one that I may not have found yet.
