To connect to eBay, 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 Ebay Sys", "", "");

Provide a Driver Connection String

To connect using an ODBC connection string:

$cnx = odbc_connect("DRIVER={CData ODBC Driver for eBay};DevID=MyDevID;OAuthClientId=MyAppID;OAuthClientSecret=MyCertID;RuName=MyRuName;SiteID=0;OAuthAccessToken=MyOAuthAccessToken", "", "");
