What are potential pitfalls of relying on ob_flush() for real-time status updates in PHP scripts?

Relying solely on ob_flush() for real-time status updates in PHP scripts can lead to inconsistent or delayed output due to server buffering or client-side buffering. To ensure real-time updates, consider using WebSockets or Server-Sent Events for a more reliable and efficient solution. 

<?php
ob_implicit_flush(true);
for ($i = 0; $i < 10; $i++) {
    echo "Progress: $i/10";
    flush();
    sleep(1); // Simulate some processing time
}
?>
