How can a browser be redirected to automatically execute a second script after the execution of the first script in PHP, considering the limitation of headers already being sent?

When headers are already sent in PHP, it becomes tricky to redirect the browser to execute a second script automatically after the first script. One way to overcome this limitation is by using output buffering to capture the output before any headers are sent. This way, you can redirect the browser to the second script without encountering the headers already sent error.

<?php
ob_start(); // Start output buffering

// Your first script here

ob_end_clean(); // Clean (erase) the output buffer without sending it to the browser

// Redirect to the second script
header("Location: second_script.php");
exit;
?>
