I don't think so:  the same technique is used by the Perl code to create the archiveReq file.  The reason that's done is to ensure a unique name, not to allow it to know what the PID is.

If you check the Server Status page while an archive is running, you'll see that BackupPC knows the PID of the process properly.

Here's a question:  have you tried using the standard GUI to start and stop an archive?  From my recollection, BackupPC won't kill the tar immediately even when it's started from its own GUI.  I usually have to go in and kill the process manually no matter how the archive job is started.  But my recollection may be incorrect.

On a different note, I would be interested to see your PHP code.
