domanda: ma hai provato ad usare direttamente le api loro? http://bdp.betfair.com/
You need to:
Step 1: Dowload and save the wsdls to the local machine
Step 2: $BFGlobalSoapClient = new SoapClient('local/file/structure/BFGlobalService.wsdl' ,array("connection_timeout"=>5));
If you refer to the PHP5 API Framework, you’ll see that the wsdl files are downloaded and stored locally. Take a look at the betfairglobalapi.class.php, specifically the betfair_api_login function – you could use this in your code (removing $use_x_ip references as below).
However, please note that due to the fact that the limited implementation of the SOAP libraries in PHP5 causes some unexpected behaviour, we created SOAPClientExtended in the API Framework (betfairutility.class.php). This resolves a known issue with nullable fields.
