You are including a file, so PHP reads the data into memory, and runs it
as a php program (i.e. it looks for <?php ...?> tags and runs any php code
it finds.)
That is, in fact, identical to what happens using the "http://server..."
syntax, except that the include gets the data from a different location.
Instead of reading the data from a file handle, it reads the data from a
socket handle. The socket is being sent the data from a web server.
In both situations the include will check for <?php tags and maybe run the
data as a php script.
In neither situation does the include ever run the file as a cgi script.
HOWEVER, since it's a local file, you can run it yourself using php
functions such as
exec() system() passthru() escapeshellcmd() pcntl_exec()
system() backtick operator
Look them up to check which would be best for you.
THE ENVIRONMENT
Because it is a cgi script it will expect certain environment variables to
be set. But since php is already running in a cgi environment then you
might not need to set any of the variables yourself - they are already
set. Whether they have the correct values for the script will depend on
what the script does. I would just give it a try and see what happens.
