Really easy question

How can i check to see if PHP has been enabled, I enabled the modules etc after they were compiled and i have managed to get Apache working properly again but now even when i do the basic tutorial stuff then I get a blank page rather than what I am supposed to get, the tutorial page is no help as all it says is "see your network admin to get PHP enabled" this is only on my home machine so I guess I am the network admin...kind of anyway...can someone please help... thanks very much biscut
