Slightly off topic... but since you mentioned it: PLEASE don't actually put literal values into your sql by string interpolation: $sql = "... thing_id = $thing_id ...";. Do it with placeholders and bind values. This can be more and less of a performance issue with different types of databases, but it is always a security issue. In some databases, I could specify a $thing_id of "5; drop table thing", and you'd be hating life. On databases where that sort of thing can't be made to work (like oracle, for example), I could still plant a denial of service attack by saying that $thing_id was 
"(select min(thing1.thing_id)
from
    thing thing1,
    thing thing2,
    thing thing3,
    thing thing4,
    thing thing5,
    thing thing6,
    thing thing7,
    thing thing8,
    thing thing9,
    thing thing10
--look!  no 'where', clause this is a 10-way cartesian product of thin
+g!
)"

You can come back in a month when your database finishes processing that query.
