PDO_MYSQL DSN — Connecting to MySQL databases
The PDO_MYSQL Data Source Name (DSN) is composed of the following elements:
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.
unix_socket
The MySQL Unix socket (shouldn't be used with host
or port).
charset
The character set. See the character set concepts documentation for more information.
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
mysql:host=localhost;port=3307;dbname=testdb mysql:unix_socket=/tmp/mysql.sock;dbname=testdb
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.
