How can caching affect the behavior of PHP code in a CMS template?

Caching can affect the behavior of PHP code in a CMS template by serving cached versions of the template instead of executing the PHP code each time a page is loaded. This can lead to outdated content being displayed or dynamic elements not functioning as expected. To solve this issue, you can disable caching for specific PHP code blocks that need to be executed dynamically. 

<?php
// Disable caching for specific PHP code block
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Pragma: no-cache"); // HTTP/1.0
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past

// Your dynamic PHP code here
?>
