What are some best practices for integrating PHP with OwnCloud's CalDAV API?

When integrating PHP with OwnCloud's CalDAV API, it is important to follow best practices to ensure smooth communication between your PHP application and the calendar server. One key practice is to use a CalDAV client library in PHP, such as Sabre/DAV, to handle the communication with the CalDAV server. This library provides a set of classes and methods to interact with the CalDAV API, making it easier to perform operations like creating, updating, and deleting events on the calendar.

<?php

require_once 'vendor/autoload.php'; // Include the Sabre/DAV library

use Sabre\DAV\Client;

// Set up the CalDAV client
$client = new Client([
    'baseUri' => 'https://your-owncloud-server.com/remote.php/dav/calendars/username/calendarname/',
    'userName' => 'username',
    'password' => 'password',
]);

// Example: Get a list of events from the calendar
$response = $client->request('PROPFIND');

// Process the response
if ($response->getStatus() === 207) {
    $xml = $response->getBodyAsString();
    // Parse the XML response and extract the events
    // Display or process the events as needed
} else {
    echo 'Error: Unable to retrieve events from the calendar';
}

?>
