∟Outdated: Get_Temperature_Dump.php - Dumping Debugging Information

This section provides a tutorial example on how to use SOAP client functions to make Web service call on the target SOAP node and print detailed debug information.

After learning the basic functions of the SoapClient class, I revised my Get_Temperature.php client program to get more information on how SOAP Extension works, and to show you how to debug a SOAP client program. The new client program is called, Get_Temperature_Dump.php: 

<?php
#  Get_Temperature_Dump.php
#- Copyright (c) HerongYang.com. All Rights Reserved.
#
   $zip = "123456";
   $client = new SoapClient
      ("http://www.xmethods.net/sd/2001/DemoTemperatureService.wsdl",
      array('trace' => 1));

   echo("\nDumping client object:\n");
   var_dump($client);

   echo("\nDumping client object functions:\n");
   var_dump($client->__getFunctions());

   $return = $client->getTemp($zip);
   echo("\nReturning value of getTemp() call: ".$return);

   $return = $client->__soapCall("getTemp",array($zip));
   echo("\nReturning value of __soapCall() call: ".$return);

   echo("\nDumping request headers:\n"
      .$client->__getLastRequestHeaders());

   echo("\nDumping request:\n".$client->__getLastRequest());

   echo("\nDumping response headers:\n"
      .$client->__getLastResponseHeaders());

   echo("\nDumping response:\n".$client->__getLastResponse());
?>

If you run this sample script, you will get: 

Dumping client object:
object(SoapClient)#1 (3) {
  ["trace"]=>
  int(1)
  ["_soap_version"]=>
  int(1)
  ["sdl"]=>
  resource(5) of type (Unknown)
}

Dumping client object functions:
array(1) {
  [0]=>
  string(30) "float getTemp(string $zipcode)"
}

Returning value of getTemp() call: 52

Returning value of __soapCall() call: 52

Dumping request headers:

The output is very useful. It confirms that:
