Does $\_POST when used in conjunction with forms in PHP have a size limit? Obviously there must be some restrictions with $\_GET seeing as most browsers will start to complain at ~250 characters (or something like that) and data could be lost, obviously this restraint doesn't apply to $\_POST.

I could test it myself but thought it might be quicker to simply ask here. If I had a simple form with a textarea, how much data could I enter before I ran into problems?
