how can i tell if a server is running zend?

II have never used the optimiser, though my guess is that it would show up somewere on the phpinfo();. Iv got a copy of it, ill put it on my server and ill c what i can find in the phpinfo.

basically i have just installed modernbill, and the php pages just look borked, ill ask the sys admin tommorrow

http://www.c0ldhost.com/phpinfo.php look at that page i got MB on my servers and it run's just fine.
