About this plugin
PHP Compatibility Scanner helps you assess whether your site’s code (plugins and themes) is likely to run on newer versions of PHP. It performs static analysis using PHP_CodeSniffer and the PHPCompatibilityWP ruleset to flag code patterns that are incompatible with the selected target PHP version.
What the plugin does (at a glance):
5).
– Scans plugins and themes, then highlights only the new issues that would appear on the target version (the “delta”).
– Shows results in a clear report on the Tools screen and adds small badges on the Plugins list screen.
– Lets you pause, resume, or stop a running scan.
Important limitations of static analysis:
– Static analysis can miss issues in dynamic code paths and can generate false positives. Treat results as guidance, not guarantees. Always test site functionality on a staging environment before upgrading PHP in production.
