What potential issues can arise when using the EventSource function in PHP for live feedback to end users?

One potential issue that can arise when using the EventSource function in PHP for live feedback to end users is that the connection may be closed unexpectedly, causing the client to miss out on updates. To solve this issue, you can implement a reconnection mechanism in the client-side code to automatically reconnect to the server if the connection is lost. 

<?php
// Server-side PHP code sending live updates to clients
header('Content-Type: text/event-stream');
header('Cache-Control: no-cache');

// Send live updates every 1 second
while (true) {
    $data = // Get live data updates here
    echo "data: " . json_encode($data) . "\n\n";
    ob_flush();
    flush();
    sleep(1);
}
?>
