How can caching affect the display of JavaScript files in a PHP project and what steps can be taken to address this issue?

Caching can affect the display of JavaScript files in a PHP project by serving outdated versions of the files, leading to functionality issues or visual discrepancies. To address this issue, you can add versioning to the JavaScript file URLs by appending a query string parameter with a unique version number or timestamp. This will force browsers to fetch the latest version of the file whenever it changes. 

<script src="js/script.js?v=1.0"></script>
