Frequently Asked Questions about php-cleanup

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I find and remove unused PHP code in WordPress plugins?▼

Detect unused PHP code in WordPress plugins by analyzing source files and composer.json with Psalm and PHP-CS-Fixer. This identifies dead code, unused imports, and orphaned dependencies to shrink autoload size and reduce bloat.

What is the best way to detect missing composer dependencies in WordPress themes?▼

Detecting missing composer dependencies in WordPress themes requires analyzing composer.json against actual PHP usage patterns using composer-require-checker. This prevents runtime errors by identifying packages referenced in code but missing from project dependencies.

Can I use composer-unused to clean up stale dependencies in PHP projects?▼

Yes, composer-unused identifies stale dependencies listed in composer.json but never referenced in the PHP source code. Removing these orphaned packages reduces project bloat and keeps the autoloader optimized for performance.

Does static analysis with Psalm help identify dead code in legacy WordPress projects?▼

Static analysis with Psalm identifies dead code in legacy WordPress projects by tracing execution paths and flagging unreachable code blocks. Combined with composer-require-checker, it guides safe cleanup of unused imports and missing dependencies without breaking runtime behavior.

Why does my WordPress plugin have bloated autoload files after cleanup?▼

Bloated autoload files in WordPress plugins occur when unused classes and stale dependencies remain in composer.json. Running composer-unused and PHP-CS-Fixer detects and prunes orphaned dependencies and dead code, shrinking the autoload footprint and boosting performance.
