How to fix the error: PHP SOAP Fatal error:uncaught soapfault exception: [Client] looks like we got no XML document?

The following code is present, and the above error occurs at run time. The reason is also clear, because __soapcall expects to return data in XML format, and if not, an error occurs.

    $webservice _url = "Http://120.25.XX. Xx:3000/service.asmx? WSDL ";//webservice address    $client = new Soapclientnew ($webservice _url); try{    $arr = $client->__soapcall (' Functionsql ', Array (' parameters ' = + $param));//Call the method}catch (Exception $e) {echo $e. getMessage ();}

1, create a new class Soapclientnew extends SoapClient {public   function __dorequest ($request, $location, $action, $version, $ One_way = 0) {   $request = parent::__dorequest ($request, $location, $action, $version, $one _way); $GLOBALS [' $soap _ Call_result '] = $request; Important! The result has been returned here, saved to the global variable//$start = Strpos ($request, ' <soap ');//According to the actual situation to do processing ... , if it is <?xml start, change to <?xml//$end = Strrpos ($request, ' > '); Return substr ($request, $start, $end-$start + 1);     return $request; }}2, calling the new class $client = Soapclientnew ($webservice _url);  try{   $arr = $client->__soapcall (' Functionsql ', Array (' parameters ' = = $param));//Call one of the methods  }catch ( Exception $e) {  }    $arr = $GLOBALS [' $soap _call_result '];//After the call to read the global variable, you can get the result of the call Print_r ($arr);
