What is the second method of abnormal reading when webservice is called?

What is the PHPcoderequire (. soap_libnusoap.php); require (. include. php); ini_set (& quot; soap. wsdl_cache_enabled & quot;, & quot; 1 & quot;); $ s what is the second method of error reading when webservice is called

PHP code

      require('./soap_lib/nusoap.php');       require('./include.php');    ini_set("soap.wsdl_cache_enabled", "1");$s = new SoapClient(url_site."/WebServices/Service1.asmx?wsdl");  $s->soap_defencoding = 'UTF-8'; $s->decode_utf8 = false;//  $result=$s->call('UserInfo',array('user'=> urldecode($_GET['username'])));   $result=$s->UserInfo(array('user'=> urldecode($_GET['username'])));    //var_dump($result);exit;//  if   (!$err=$s->getError())   {   //   $list=explode(";",$result["UserInfoResult"]);//   array_pop($list);//  }   else   {      $list=explode(";",$result->UserInfoResult);   array_pop($list); ?>

The comments are based on the previous method of calling ws, which is not supported after the host is changed. then, we went to Google and found the second method, but did not specify how to capture the error message.

The cause is that if
$ Result = $ s-> UserInfo (array ('user' => urldecode ($ _ GET ['username']);

No data is executed.
