Are there alternative methods or libraries that can be used to successfully retrieve calendar events from iCloud using PHP?

To retrieve calendar events from iCloud using PHP, you can use the iCloud API provided by Apple. This API allows you to authenticate with iCloud and access calendar data. Alternatively, you can use third-party libraries like the `iCloud` library for PHP, which simplifies the process of interacting with iCloud services.

// Example using the iCloud library for PHP
require 'vendor/autoload.php';

use Apple\iCloud;

$icloud = new iCloud('username', 'password');
$events = $icloud->calendar()->getEvents();

foreach ($events as $event) {
    echo $event['summary'] . ' - ' . $event['start'] . ' to ' . $event['end'] . PHP_EOL;
}
