Research Description
PHP Compatibility Checker is a WordPress plugin developed by WP Engine that helps site administrators and developers analyze their WordPress themes and plugins for compatibility with modern PHP versions. As WordPress continues to evolve, maintaining compatibility with supported PHP versions is a crucial factor for both performance and security. Outdated PHP releases no longer receive security updates, leaving websites at risk of vulnerabilities. This plugin empowers users to safely transition to newer PHP versions (up to PHP 8.0) by identifying errors and warnings in their installed codebase. The tool uses linting technology combined with Tide’s scanning infrastructure to analyze plugin and theme files. It generates detailed reports with file names, line numbers, and descriptions of incompatibilities. Additionally, it recommends plugin or theme updates if newer versions include PHP compatibility fixes.
