You can, if you are careful, write an SQL procedure for dropping the appropriate tables.
Since MySQL has no table variables, if you do this you will need PREPARE.
Therefore, it well may be easier to do it all in PHP, since therewith you can construct
statements. The statement "SHOW TABLES" is also a reference to table
INFORMATION_SCHEMA.TABLES; maybe you can use "SHOW TABLES" for a SELECT statement in PHP;
if not, try INFORMATION_SCHEMA.TABLES for their names.
