Let's see what we can do. What about "select * from $table_name where 9=0"? For most db drivers that I know, that will either fail in the prepare or the execute if the table doesn't exist. You should be able to trap that error and act accordingly. Moreover, it won't actually fetch any data, so it's good from a data throughput standpoint. :)

Be your own disciple, fan the sparks of will
For all of us waiting, your kingdom will come
