error ใน web service (upload file) จะทำยังไงดีอะคะ รบกวนใครที่รู้ช่วยหน่อยนะคะ ขอบคุณคะ^^

<?
   require_once('lib/nusoap.php'); //include required class for build nnusoap web service server
   $wsdl="http://localhost/testtest/sendfile/ImageSer.php?wsdl";  // SOAP Server

   if($_POST['submit'])
   {
       $tmpfile = $_FILES["uploadfiles"]["tmp_name"];   // temp filename
       $filename = $_FILES["uploadfiles"]["name"];      // Original filename

       $handle = fopen($tmpfile, "r");                  // Open the temp file
       $contents = fread($handle, filesize($tmpfile));  // Read the temp file
       fclose($handle);                                 // Close the temp file

       $decodeContent= base64_encode($contents); // Decode the file content, so that we code send a binary string to SOAP
    }   

   $client=new soapclient($wsdl) or die("Error");   // Connect the SOAP server
   
   $response = $client->call('upload_file',array($decodeContent,$filename)) or die("Errorresponse"); 
   
  
   //Send two inputs strings. {1} DECODED CONTENT {2} FILENAME

   // Check if there is anny fault with Client connecting to Server
   if($client->fault){
        echo "Fault {$client->faultcode} <br/>";
        echo "String {$client->faultstring} <br/>";
   }
   else{
        print_r($response); // If success then print response coming from SOAP Server
   }
