How can the issue of only displaying one entry for each event in the live ticker be resolved in PHP?

Issue: The problem of only displaying one entry for each event in the live ticker can be resolved by storing the unique event IDs in an array and checking if an event has already been displayed before adding it to the ticker. PHP Code Snippet: 

// Array to store unique event IDs
$displayedEvents = array();

// Loop through events
foreach ($events as $event) {
    // Check if event ID has already been displayed
    if (!in_array($event['id'], $displayedEvents)) {
        // Display event in live ticker
        echo $event['title'] . ': ' . $event['description'] . '<br>';
        
        // Add event ID to displayedEvents array
        $displayedEvents[] = $event['id'];
    }
}
