What are the potential issues when using the header() function in PHP for redirection based on time conditions?

One potential issue when using the header() function in PHP for redirection based on time conditions is that the headers must be set before any output is sent to the browser. To solve this, you can use output buffering to capture any output before sending headers. 

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

// Your time condition logic here
if (time() >= strtotime('2022-01-01')) {
    header('Location: https://example.com/newpage.php');
}

ob_end_flush(); // Flush the output buffer
?>
