So, those of you who know PHP like the back of your hands … What’s the best way to use PHP to determine if a web browser supports JavaScript?
I don’t know of any way. Why are you trying to determine this in PHP? If you’re worried about browsers that don’t support Javascript, try using the [noscript] tag.
The reason, I suppose, is because I came up with this brilliant idea at a quarter of 1 AM, with some other stuff on my mind.
