PDO_MYSQL is a driver that implements the <link linkend="ref.pdo">PHP
|
|
Data Objects (PDO) interface</link>
|
|
to enable access from PHP to MySQL 3.x, 4.x and 5.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: Some MySQL table types (storage engines) do not support transactions. When
|
|
writing transactional database code using a table type that does not support
|
|
transactions, MySQL will pretend that a transaction was initiated successfully.
|
|
In addition, any DDL queries issued will implicitly
|
|
commit any pending transactions.
