Check if a database table exists using PHP/PDO

Question

I want to check if a table with a specific name exists in a database I\'ve connected to using PHP and PDO.

It has to work on all database backends, like MySQL, SQLi

Answer 1

This seems to work at least with SQLite3 without exceptions, etc:

        $select =
            "SELECT CASE WHEN EXISTS (SELECT * FROM SQLITE_MASTER WHERE TYPE = 'table' AND NAME = :tableName) THEN 1 ELSE 0 END AS TABLE_EXISTS;";
