What steps should be taken to prevent header-related errors when developing locally with XAMPP and then uploading to a web server like all-inkl?

When developing locally with XAMPP and then uploading to a web server like all-inkl, it's important to ensure that there are no header-related errors. One common issue is sending headers after content has already been outputted to the browser, which can cause errors. To prevent this, make sure to not output any content before sending headers in your PHP scripts. 

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

// Your PHP code here

ob_end_flush(); // End output buffering and flush content
