Are there best practices for ensuring header(location: $url) works consistently across different browsers and security settings?

When using the `header(location: $url)` function in PHP to redirect users to a different page, it's important to ensure that no output has been sent to the browser before calling this function. To prevent any headers already sent errors, you can use output buffering to capture any output before sending headers. This will help ensure consistent behavior across different browsers and security settings. 

<?php
ob_start();
// Your PHP code here

// Redirect to a different page
$url = "https://www.example.com";
header("Location: $url");
exit();
ob_end_flush();
?>
