How can caching affect the display of PHP pages and potentially lead to errors like the one experienced by the user in the thread?

Caching can affect the display of PHP pages by serving outdated content to users. This can lead to errors if the cached version of a page contains outdated or incorrect information. To solve this issue, you can disable caching for dynamic PHP pages by setting appropriate cache-control headers. 

<?php
header("Cache-Control: no-cache, must-revalidate"); // Disable caching for this PHP page
?>
