What are the best practices for handling output errors in PHP when trying to redirect users to a different page?

When handling output errors in PHP and trying to redirect users to a different page, it is important to ensure that no output has been sent to the browser before the redirection header is set. To achieve this, you can use output buffering to capture any output and prevent it from being sent prematurely. Once the header is set, you can safely redirect the user to the desired page. 

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

// Your PHP code here

if ($error_occurred) {
    header("Location: error_page.php");
    exit(); // Ensure no further code is executed after the redirection
}

ob_end_flush(); // Flush the output buffer and send it to the browser
?>
