说明

The PDO_ODBC Data Source Name (DSN) is composed of the following elements:

DSN prefix: The DSN prefix is odbc:. If you are connecting to a database cataloged in the ODBC driver manager or the DB2 catalog, you can append the cataloged name of the database to the DSN.
DSN: The name of the database as cataloged in the ODBC driver manager or the DB2 catalog. Alternately, you can provide a complete ODBC connection string to connect to a database as described at http://connectionstrings.com.
UID: The name of the user for the connection. If you specify the user name in the DSN, PDO ignores the value of the user name argument in the PDO constructor.
PWD: The password of the user for the connection. If you specify the password in the DSN, PDO ignores the value of the password argument in the PDO constructor.
