I wish to call a /usr/local/bin/pgp program and then put the output into a variable, which way best?

You will want to use one of the external program execution calls such as
system or exec. These will give you the entire output of the program
that was run, but please be cautioned that the PHP script will halt
until the program has finished executing, and will hang forever if a
prompt is required such as "OK To Continue (y/n)?". Please make sure
that you check any user input that goes to these programs.
