What are the implications of manipulating cache headers in the manifest file for PHP applications?

Manipulating cache headers in the manifest file for PHP applications can lead to inconsistent caching behavior and potential issues with browser caching. To solve this issue, it is important to properly configure cache headers to ensure that resources are cached correctly and efficiently. 

<?php
// Set cache headers for manifest file
header("Cache-Control: no-cache, must-revalidate");
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");

// Output manifest file content
echo file_get_contents('manifest.json');
?>
