SQL statements-PHP PDO there are several preset objects, I now know two, but also hope to tell you something else.

At the moment I know $pdo =new PDO ("mysql:host=localhost; ...);

There are also $stmt= $pdo->prepare () preset objects.

There are other powerful, or useful, commonly used preset objects, I hope you share with me.

Thank you!!!
