Follow The Redirected URL in PHP
===

I want to follow this link in PHP:
http://www.botsistemi.com/play/ZmlsbWlmdWxsaXpsZV90d2l0Jl8mX09TWFdN.mp4

I tried lots of thing but I couldn't reach anything. But browser redirects me to this page:
http://llcdn8.twitvid.com/twitvidvideosv2/O/S/X/OSXWM.mp4?e=1343496720&r=twitvid.com,telly.com&h=749af7043fa3a74b3af43408f94dc933

I need the follow the redirection with PHP.

Please show me a way.

Thanks,
