External script

Hi guys I am trying to write external Php script and return module codes and match those module codes using unlang . My script is being called and I can see that in debug. The error I get here is . Failed parsing output from script.php attributes : expecting operator I am returning values as 1 for success and 0 for fail Ultimately radius says module fail. I would be checking what operators to return value from Php script. Thanks in advance guys Regards Amit B
