You should be able to use SELECT ... INTO OUTFILE to write the results
of a SELECT statement out to a file on the server's filesystem. Since
you can SELECT things that don't actually reference any table, this
should let you write arbitrary data to the filesystem with the
permissions of the database user.

Since it uses PHP, I would try to find a writable, web-accessible
directory on the server and do something like

SELECT '<?php some_evil_php_code ?>' INTO OUTFILE '/var/www/accessible_by_db/';

Have fun :)
