MYSQL和PDO_MYSQL 那个更好速度更快？
MYSQL和PDO_MYSQL 那个更好速度更快？

PDO 是官方推荐的，更为通用的数据库访问方式，如果你没有特殊需求，那么你最好学习和使用 PDO.
但如果你需要使用 MySQL 所特有的高级功能，那么你可能需要尝试一下 MySQLi, 因为 PDO 为了能够同时在多种数据库上使用，不会包含那些 MySQL 独有的功能。
MySQLi 是 MySQL 的增强接口，同时提供面向过程和面向对象接口，也是目前推荐的 MySQL 驱动，旧的C风格 MySQL 接口将会在今后被默认关闭。
速度没有比过。
但是哪个更好来说，当然是PDO更好。mysql那套接口根本就没有预编译的功能，防止注入的话最好还是用PDO（或者mysqli）。
Mysqli 或 PDO 都可以，不要再使用 Mysql 驱动 了
