To connect to SAP Business One, 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 SAPBusinessOne Sys", "", "");

Provide a Driver Connection String

To connect using an ODBC connection string:

$cnx = odbc_connect("DRIVER={CData ODBC Driver for SAP Business One};Url=http://localhost:50000/b1s/v1;User=username;Password=password;CompanyDB=dbname;", "", "");
