What could be causing the issue with the header Location function not working as expected in the PHP script provided?

The issue with the header Location function not working as expected in the PHP script could be due to output being sent to the browser before the header function is called. To solve this, make sure there is no whitespace or HTML tags before the header function call. Additionally, ensure that the header function is called before any output is sent to the browser.

<?php
// Ensure no whitespace or HTML tags before the header function call
ob_start();

// Your PHP code here

// Redirect using the header function
header("Location: https://www.example.com");
exit();
ob_end_flush();
?>
