Hello. I have a database which I have abstracted off with a set of
functions I have written. (So all the correct quoting and unquoting are all
in one place.)

/* Simplified code. */

$tokenCount = getTokenCount($userIdx);
/* Context switch! */
setTokenCount($userIdx, $tokenCount + 1);

But what if another process perfoms a get on the same record between the
get and the set of the first process? What I could do with is a mutex.

Do they please exist for PHP running under Apache?

Bill, lost update.
