DSN prefix: The DSN prefix is mysql:.
host: The hostname on which the database server resides.
port: The port number where the database server is listening.
dbname: The name of the database.

The following example shows a PDO_MYSQL DSN for connecting to MySQL databases:

mysql:host=localhost;dbname=testdb

More complete examples:

mysql:host=localhost;port=3307;dbname=testdb
mysql:unix_socket=/tmp/mysql.sock;dbname=testdb

Примечания

Замечание: Unix only:

When the host name is set to "localhost", then the connection to the server is made thru a domain socket. If PDO_MYSQL is compiled against libmysql then the location of the socket file is at libmysql's compiled in location. If PDO_MYSQL is compiled against mysqlnd a default socket can be set thru the pdo_mysql.default_socket setting.
