PHP-EWS No Data Received Message - exchangewebservices

Question

I just downloaded PHP-EWS, installed following the README instructions, and spun up a script to test out its functionalities. When I try running the script in my browser, I get the following message:
I get the same message when I supply a login I know is invalid. It seems I am connecting to my Exchange server, but it's not recognizing the credentials I provide.
Here is the script I am using
<?php
function __autoload($className)
{
$className = str_replace('_','/', $className);
$sFileName = $className . '.php';
if (file_exists($sFileName) && !class_exists($className))
{
require_once $sFileName;
}
// If the above if fails, you're program will terminate, there is no way to catch this.
}
include("ExchangeWebServices.php");
$host = "https://myexchange/EWS/Services.wsdl";
$username = "myusername#mydomain.com";
$password = "mypassword";
$ews = new ExchangeWebServices($host, $username, $password);
$request = new EWSType_FindItemType();
$request->ItemShape = new EWSType_ItemResponseShapeType();
$request->ItemShape->BaseShape = EWSType_DefaultShapeNamesType::DEFAULT_PROPERTIES;
$request->Traversal = EWSType_ItemQueryTraversalType::SHALLOW;
$request->ParentFolderIds = new EWSType_NonEmptyArrayOfBaseFolderIdsType();
$request->ParentFolderIds->DistinguishedFolderId = new EWSType_DistinguishedFolderIdType();
$request->ParentFolderIds->DistinguishedFolderId->Id = EWSType_DistinguishedFolderIdNameType::INBOX;
// sort order
$request->SortOrder = new EWSType_NonEmptyArrayOfFieldOrdersType();
$request->SortOrder->FieldOrder = array();
$order = new EWSType_FieldOrderType();
// sorts mails so that oldest appear first
// more field uri definitions can be found from types.xsd (look for UnindexedFieldURIType)
$order->FieldURI->FieldURI = 'item:DateTimeReceived';
$order->Order = 'Ascending';
$request->SortOrder->FieldOrder[] = $order;
$response = $ews->FindItem($request);
echo '<pre>'.print_r($response, true).'</pre>';
?>

Answer 1

Try testing your access by:
Hitting the server url directly: https://YOUREXCHANGESERVER/EWS/Services.wsdl
You should be prompted for credentials. After you enter your credentials you will be presented with the WSDL definition. If it does not present you a WSDL definition that looks like the example below then check with your administrator on credentials or if there are any firewall blocks put in place.
Example (Partial response):
<wsdl:definitions targetNamespace="http://schemas.microsoft.com/exchange/services /2006/messages"><wsdl:types><xs:schema><xs:import namespace="http://schemas.microsoft.com/exchange/services/2006/messages" schemaLocation="messages.xsd"/></xs:schema></wsdl:types>
