[PHP-CLI] Accessing Input Lines from Functions Utilizing "-F"

Ok,

So I am running PHP in interactive mode utilizing the PROCESS command line
option -F. I type the following command:

c:\php\php.exe -a -F myfile.php

When I run this command, I receive the "Interactive Mode Enabled" prompt.
My question is, once I start keying in information and the program
"myfile.php" is called, how do I get to the information that I just typed in
on STDIN? If I attempt to use fgets(STDIN,255);, it does not get the first
command only my next one. If I attempt to use the $_SERVER[...] variables,
I only get information on "myfile.php" and not the input line I typed in.

Let me explain.

C:\i>c:\php\php.exe -a -F myfile.php
Interactive mode enabled

test <cr>
// my function myfile.php is now called. The question is how do I retreive
the input line "test" from myfile.php????

Thanks in Advance,
