MySQL (PDO)

&reftitle.intro; PDO_MYSQL is a driver that implements the PHP Data Objects (PDO) interface to enable access from PHP to MySQL 3.x and 4.x databases. PDO_MYSQL will take advantage of native prepared statement support present in MySQL 4.1 and higher. If you're using an older version of the mysql client libraries, PDO will emulate them for you. Beware: MySQL tables do not support transactions by default. When writing transactional database code, MySQL will pretend that a transaction was initiated successfully, even when no transactional support is present. In addition, any DDL queries issued will implicitly commit any pending transactions.
