CL PHP

Hi All,

I am trying to do some command line PHP, and I note that when I type 'php'
and hit enter, it does start up PHP. But how do I get it to do anything?
'man php' says that "If no parameter is present then the standard input is
read and executed." But I cannot get to execute anything - either that or I
am not seeing the output.

I have tried ctrl-d, ctrl-c, and ctrl-z. None of them seem to get it to
actually execute. Any pointers?

Sincerely,
-Josh
