PHP mobile browser detection?

I'm in need of a way to detect mobile browsers server-side. I'd like a way that requires me to do little to set up and little to maintain, yet still provide me with accurate detection of (at the VERY least) Android, Mobile Safari and Blackberry browsers, along with alternatives like Opera.

I'd like to have at least the majority of the mobile market covered, and I'd really prefer virtually all of the market if it doesn't take much.

Solution 1:

WURLF is the ultimate way for mobile browser detection and a PHP API is available.

Solution 2:

I found this one to be very easy to use php-mobile-detect
