What could be causing the issue with the "Header Location" function not redirecting properly in PHP?

The issue with the "Header Location" function not redirecting properly in PHP could be due to output being sent to the browser before the function is called. To solve this, make sure there is no whitespace or any other output before the "Header Location" function is called.

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

// Your PHP code here

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