What are some resources or tutorials available for resolving header modification errors in PHP, specifically when trying to redirect within a script?

When encountering header modification errors in PHP, particularly when trying to redirect within a script, it is important to ensure that no output has been sent to the browser before calling the header() function. To resolve this issue, you can use output buffering to capture any output before sending headers. 

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

// Your PHP code here

ob_end_clean(); // Clean (erase) the output buffer
header('Location: http://www.example.com'); // Redirect to the specified URL
exit(); // Ensure no further code is executed after the redirect
?>
