Keeping your website updated is essential for security and performance. PHP versions change over time, and outdated code can cause issues. A PHP Compatibility Checker helps detect problems before upgrading. This tool ensures that your website runs smoothly on the latest PHP version.
For WordPress and other CMS platforms, using a PHP Compatibility Checker prevents errors and broken features. In this article, we will explore the best plugins available.
