To connect to SAP Ariba, 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 SAPAribaSource Sys", "", "");

Provide a Driver Connection String

To connect using an ODBC connection string:

$cnx = odbc_connect("DRIVER={CData ODBC Driver for SAP Ariba Source};API=SupplierDataAPIWithPagination-V4;APIKey=wWVLn7WTAXrIRMAzZ6VnuEj7Ekot5jnU;Environment=SANDBOX;Realm=testRealm;AuthScheme=OAuthClient;InitiateOAuth=GETANDREFRESH;OAuthClientId=testClient;OAuthClientSecret=testClientSecret;", "", "");
