PDO Object
Medoo是一个基于PDO的项目.你通过 $database->pdo, 能够使用更多的PDO方法, 预定义,事务 , 回滚 等.
更多关于 PDO 的使用, 请阅读: http://php.net/manual/en/class.pdo.php.
Transaction (事务)
$database->pdo->beginTransaction();
$database->insert("account", [
"user_name" => "foo",
"email" => "foo@bar.com",
"age" => 25
]);
/* Commit the changes */
$database->pdo->commit();
/* Recognize mistake and roll back changes */
$database->pdo->rollBack();
Prepare
有时候Medoo不能处理一些复杂的PDO时，你可以使用它来完成.
$calories = 150;
$colour = 'red';
$sth = $database->pdo->prepare('SELECT name, colour, calories
FROM fruit
WHERE calories < :calories AND colour = :colour');
$sth->bindParam(':calories', $calories, PDO::PARAM_INT);
$sth->bindParam(':colour', $colour, PDO::PARAM_STR, 12);
$sth->execute();
