You can test WordPress plugin compatibility across multiple PHP and WP versions by running a full matrix compatibility check via bash scripts. The Skill simulates plugin execution across multiple PHP and WordPress environments to identify incompatibilities before deployment.

WordPress plugin compatibility testing checks whether a plugin functions correctly across various PHP and WordPress versions. You need it before deployment or after WordPress core updates to identify PHP syntax issues and modern WP feature incompatibilities.

Multiple environments are required for testing and analyzing PHP version compatibility. The Skill simulates live plugin execution across different PHP and WordPress environments to detect target version syntax issues and feature incompatibilities.

To check for PHP syntax issues on older WordPress versions, the Skill performs static PHP compatibility scanning against your target versions. It evaluates your plugin's use of modern WordPress features and identifies incompatibilities with older environment standards.

The best way to verify compatibility after a WordPress core release is running a full matrix test. The Skill assists with post-release checks by simulating plugin execution across the updated WordPress core and various PHP versions.

You should bump the minimum PHP version for your WordPress plugin based on decision rules provided by the compatibility matrix. These guidelines help determine compatibility actions when static scanning or live multi-version testing reveal incompatibilities with your current target.
