How can PHP output buffering be integrated with error handling to ensure a smooth user experience on a website?

PHP output buffering can be integrated with error handling by using try-catch blocks to catch any exceptions that may occur during the execution of the code. By buffering the output, errors can be captured and handled gracefully without disrupting the user experience on the website.

<?php
ob_start();

try {
    // Code that may throw exceptions
} catch (Exception $e) {
    ob_clean(); // Clear output buffer
    echo "An error occurred: " . $e->getMessage();
}

ob_end_flush(); // Send buffered output to the browser
?>
