What are the best practices for avoiding server and browser limitations when trying to achieve live output with PHP?

To avoid server and browser limitations when trying to achieve live output with PHP, it's best to use techniques like server-sent events (SSE) or WebSockets instead of traditional polling methods. These technologies allow for real-time updates without overloading the server or browser with unnecessary requests. 

<?php
header('Content-Type: text/event-stream');
header('Cache-Control: no-cache');

// Your live output code here
echo "data: Live output here\n\n";
flush();
?>
