I setup credit card charging with a combination of php and perl. It's
running on a shared server, so I had to use a protected perl script with
the constants like passwords and hash keys in the script. The script is
run by CGIwrap under my account's UID rather than as the web server's
UID.
Perl seems to be suited to do SSL submissions to authorize.net, receive,
and process their reply. I had no problems getting it to work with
their excellent documentation. I didn't see away of getting PHP to do
it and the Perl CPAN modules to emulate a browser client worked without
problems.
