示例

示例 #1 PDO_MYSQL DSN examples

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

注释

注意: Unix only:

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