What are common issues with PHP header redirection and how can they be resolved?

One common issue with PHP header redirection is that headers must be sent before any output is displayed on the page. To resolve this, make sure that there is no whitespace or output before the header() function is called. 

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

// Your PHP code here

ob_end_clean(); // Clean the output buffer
header("Location: https://www.example.com"); // Redirect to the desired location
exit();
?>
