Well if you're caching per-connection then it doesn't really matter whether
you do it on the client side or the server side, it's pretty much exactly the
same problem.
Unsurprisingly most drivers do precisely what you're describing. In Perl DBI
for example you just change $dbh->prepare("") into $dbh->prepare_cached("")
and it does exactly what you want. I would expect the PHP drivers to have
something equivalent.
