Depends. What version of mysql you are using? If you are using mysql 3.x and/or
non-innodb tables, you don't have transactions in first place. Mysql does not
need autocommit in earlier version because it does not have transactions in
first place.

Against mysql? I doubt. You can try scaling number of concurrent connections and
number of rows in database. Furthermore don't do bulk update but do selective
random updates. And verify the results in your php section.
