Connecting
To connect to DB2, you can use either a DSN or an ODBC connection string. Both of these methods use the odbc_connect function.
Connect to a DSN
To connect using a DSN:
$cnx = odbc_connect("CData DB2 Sys", "", "");
Provide a Driver Connection String
To connect using an ODBC connection string:
$cnx = odbc_connect("DRIVER={CData ODBC Driver for DB2};Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test", "", "");
