In the context of PHP usage, what alternatives exist for setting Cache-Control headers if a provider does not allow modifications via .htaccess?

If a provider does not allow modifications via .htaccess, an alternative for setting Cache-Control headers in PHP is to use the header() function to send the appropriate headers in the response. This can be achieved by setting the "Cache-Control" header to control caching behavior for the browser. 

<?php
// Set Cache-Control header to control caching behavior
header("Cache-Control: no-cache, no-store, must-revalidate");
header("Pragma: no-cache");
header("Expires: 0");
?>
