PHP-EWS 2010, how to set the IsRead flag - php

Question

I have been able to successfully retrieve the unread emails from an Exchange 2010 inbox using php-ews API. However after I have fetched the emails, I want to set the IsRead property of the email to true, so that these messages do not appear the next time I fetch emails.
Anyone done this before ?
EDIT :
This is how I am trying to set the IsRead flag :
$message_id = ''; //id of message
$change_key = ''; //change key
$response = $ews->GetItem($request);
//print_r($response);exit;
if( $response->ResponseMessages->GetItemResponseMessage->ResponseCode == 'NoError' &&
$response->ResponseMessages->GetItemResponseMessage->ResponseClass == 'Success' ) {
$a = array();
$message = $response->ResponseMessages->GetItemResponseMessage->Items->Message;
$a['message_body'] = $message->Body->_;
$a['sender'] = $message->From->Mailbox->EmailAddress;
$a['subject'] = $message->ConversationTopic;
$data[] = $a;
//process the message data.
$messageType = new EWSType_MessageType();
$messageType->IsRead = true;
$path = new EWSType_PathToUnindexedFieldType();
$path->FieldURI = 'message:IsRead';
$setField = new EWSType_SetItemFieldType();
$setField->Message = $messageType;
$setField->FieldURI = $path;
$u = new EWSType_ItemChangeType();
$u->Updates = new EWSType_NonEmptyArrayOfItemChangeDescriptionsType();
$u->Updates->SetItemField = $setField;
$u->ItemId = new EWSType_ItemIdType();
$u->ItemId->Id = $message_id;
$u->ItemId->ChangeKey = $change_key;
$updatedItems = new EWSType_NonEmptyArrayOfItemChangesType();
$updatedItems->ItemChange = $u;
$updateMessenger = new EWSType_UpdateItemType();
$updateMessenger->ItemChanges = $updatedItems;
$updateMessenger->MessageDisposition = 'SaveOnly';
$updateMessenger->ConflictResolution = 'AutoResolve';
try {
$update_response = $ews->UpdateItem($updateMessenger);
}catch (Exception $e){
echo $e->getMessage();
}
}
When I run the file I get the following error :
An internal server error occurred. The operation failed.
After debugging for some time, I have concluded that the error happens at the curl_exec function in NTLMSoapClient.php file.
I dont know where to go on from here. Please help.

I've faced a similar issue when updating a calendar event and setting the IsAllDayEvent flag. This is the code that worked for me:
$ews = new ExchangeWebServices(...);
$request = new EWSType_UpdateItemType();
$request->ConflictResolution = 'AlwaysOverwrite';
$request->ItemChanges = array();
$change = new EWSType_ItemChangeType();
$change->ItemId = new EWSType_ItemIdType();
$change->ItemId->Id = $id;
$change->ItemId->ChangeKey = $changeKey;
$field = new EWSType_SetItemFieldType();
$field->FieldURI = new EWSType_PathToUnindexedFieldType();
$field->FieldURI->FieldURI = "calendar:IsAllDayEvent";
$field->CalendarItem = new EWSType_CalendarItemType();
$field->CalendarItem->IsAllDayEvent = true;
$change->Updates->SetItemField[] = $field;
$request->ItemChanges[] = $change;
$response = $ews->UpdateItem($request);
The biggest difference I see here is that you do $u->Updates->SetItemField = $setField;, whereas my code uses $u->Updates->SetItemField[] = $setField;.
I hope this helps.
Edit: You might have already seen this, but I based my code on the one from the php-ews wiki.

I tried everything including PathToExtendedFieldType and it doesn't work at the end code below worked for me
$ews = new ExchangeWebServices('red', 'red', 'red',ExchangeWebServices::VERSION_2007_SP1);
$request = new EWSType_UpdateItemType();
$request->SendMeetingInvitationsOrCancellations = 'SendToNone';
$request->MessageDisposition = 'SaveOnly';
$request->ConflictResolution = 'AlwaysOverwrite';
$request->ItemChanges = array();
// Build out item change request.
$change = new EWSType_ItemChangeType();
$change->ItemId = new EWSType_ItemIdType();
$change->ItemId->Id = $contact_id;
$change->ItemId->ChangeKey = $contact_change_key;
#$change->Updates = new EWSType_NonEmptyArrayOfItemChangeDescriptionsType();
#$change->Updates->SetItemField = array();
// Build the set item field object and set the item on it.
$field = new EWSType_SetItemFieldType();
$field->FieldURI = new EWSType_PathToUnindexedFieldType();
$field->FieldURI->FieldURI = "message:IsRead";
$field->Message = new EWSType_MessageType();
$field->Message->IsRead = true;
$change->Updates->SetItemField[] = $field;
$request->ItemChanges[] = $change;
$response = $ews->UpdateItem($request);
var_dump($response);

Well, i dont know how it is in php, but in C# there is another field, that must be set: IsReadSpecified = true.
email.IsRead = true;
email.IsReadSpecified = true;
