Examples
Example #1 PDO_MYSQL DSN examples
The following example shows a PDO_MYSQL DSN for connecting to MySQL databases:
mysql:host=localhost;dbname=testdb
mysql:host=localhost;port=3307;dbname=testdb mysql:unix_socket=/tmp/mysql.sock;dbname=testdb
Notes
Note: 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.
