scp a file wo pbuttword FROM remote to local

I have an Apache server and a seperate mySQL server. A PHP script on the Web server runs a SQL "INTO OUTFILE" which creates a file... on the mySQL server. So in order to continue working with the file and make it accessible through the Web, I need to copy it over to the Apache machine.

I tried executing an "rsync" command, but can't find a way to bypbutt a pbuttword or force it to use a particular user. Having done pbuttwordless scp before, I went that route. Created mutual users, keys, etc, and can ssh-scp using that username and no pbuttword.

If I run this (as root) it works: scp -ihome-scotty-.ssh-idrsa -B -C -P 22pa-accounts-samplesdownload-1137004466.txt

Problem is, come to find out, the scp can't be run in a PHP script as another user. Even if I copy the idrsa into a folder apache can access (NOT a good idea!! I just did that to test if it'd work.) And I'm not about to make apache a pbuttword-less account.

What can I do to make this happen? If someone could just give me the name of the command I should look into I'll look up the docs. If rsync or scp really is still the answer, give me a RTFM and I'll keep looking--because at the moment I'm not finding anything in the MANs that will get me further than I am. Thanks -Liam
