使用PHP EWS删除定期日历项目？

The past couple of days I have been learning to use the PHP-EWS class for reading/updating/deleting calendar entries. I have been able to create single events, read all calendar events for a day and remove events. My problem is that I cannot find any information in regards to deleting an entire series of recurring events. When I delete an event the code I have only deletes the entry of 1 event and not all instances of the recurrence.

Not sure if I am just passing the wrong Id and ChangeKey to the delete code or if there is special code to handle recurring events.

My code for deleting events is as follows:

<?php
// Define the delete item class
$request = new EWSType_DeleteItemType();
// Send to trash can, or use EWSType_DisposalType::HARD_DELETE instead to bypass the bin directly
$request->DeleteType = EWSType_DisposalType::MOVE_TO_DELETED_ITEMS;
$request->SendMeetingCancellations = EWSType_CalendarItemCreateOrDeleteOperationType::SEND_ONLY_TO_ALL;

$items = new EWSType_NonEmptyArrayOfBaseItemIdsType();
foreach ($IDs as $id) {
// Set the item to be deleted
    $item = new EWSType_ItemIdType();
    $item->Id = $id['Id'];
    $item->ChangeKey = $id['ChangeKey'];
    $items->ItemId[] = $item;
}
$request->ItemIds = $items;
// Send the request
$response = $this->ews->DeleteItem($request);
?>

UPDATE:

I have created a class to handle most of my EWS commands. Here is a function I created to handle getting the master event IDs.

public function GetMasterEventID($EventID)
{
    if (empty($EventID)) {
        return false;
    }


    $types = array('GetItemType', 'ItemQueryTraversalType', 'ItemResponseShapeType',
                   'DefaultShapeNamesType', 'NonEmptyArrayOfPathsToElementType', 'PathToUnindexedFieldType', 
                   'NonEmptyArrayOfBaseItemIdsType', 'RecurringMasterItemIdType');
    $this->LoadTypes($types);


    $request = new EWSType_GetItemType();
    $request->Traversal = EWSType_ItemQueryTraversalType::SHALLOW;
    $request->ItemShape = new EWSType_ItemResponseShapeType();
    $request->ItemShape->BaseShape = EWSType_DefaultShapeNamesType::ID_ONLY;

    $properties = array('item:Subject', 'item:Categories', 'item:DateTimeCreated',
                        'item:LastModifiedTime', 'item:Sensitivity', 'item:ItemClass',
                        'calendar:Start', 'calendar:End', 'calendar:CalendarItemType',
                        'calendar:IsRecurring', 'calendar:Recurrence', 'calendar:FirstOccurrence',
                        'calendar:LastOccurrence', 'calendar:ModifiedOccurrences', 'calendar:DeletedOccurrences');
    $request->ItemShape->AdditionalProperties = new EWSType_NonEmptyArrayOfPathsToElementType();
    foreach ($properties as $p) {
        $entry = new EWSType_PathToUnindexedFieldType();
        $entry->FieldURI = $p;
        $request->ItemShape->AdditionalProperties->FieldURI[] = $entry;
    }

    $request->ItemIds = new EWSType_NonEmptyArrayOfBaseItemIdsType();
    $request->ItemIds->RecurringMasterItemId = new EWSType_RecurringMasterItemIdType();
    $request->ItemIds->RecurringMasterItemId->OccurrenceId = $EventID;

    $response = $this->ews->GetItem($request);
    return $response;
}

The LoadTypes() function just loops through the EWSType files that are required and then includes them so I don't have to load every type file.

You first need to find the ID of the master appointment of the recurring series, then delete that master.

I don't 'do' PHP, but these are the actual SOAP calls doing the trick. Maybe they help you back on track:

Get recurring master ID (and some data) from an occurrence:
