In the context of the PHP forum thread, how could the script be adapted to group events based on both date and group, as requested by the user?

To group events based on both date and group, the script can be adapted by using a multidimensional array to store events grouped by date and then by group. This way, events can be easily accessed and displayed based on both criteria.

// Sample code snippet to group events by date and group
$events = array();

// Loop through events and group them by date and group
foreach ($eventsData as $event) {
    $date = $event['date'];
    $group = $event['group'];

    $events[$date][$group][] = $event;
}

// Display events grouped by date and group
foreach ($events as $date => $groups) {
    echo "<h3>Date: $date</h3>";
    
    foreach ($groups as $group => $groupEvents) {
        echo "<h4>Group: $group</h4>";
        
        foreach ($groupEvents as $event) {
            echo $event['name'] . "<br>";
        }
    }
}
