Phpstan Wordpress Laravel Package

Product Decisions This Supports

• Enhancing Code Quality & Developer Experience (DX):

  • Integrate static analysis into WordPress development workflows to reduce runtime errors, improve maintainability, and accelerate onboarding.
  • Align with engineering best practices by enforcing type safety and consistency in a PHP-heavy ecosystem (WordPress powers ~43% of all websites).
  • Roadmap: Prioritize this for projects with:
    • Custom WordPress plugins/themes (high risk of type-related bugs).
    • Teams adopting modern PHP (8.1+) or strict coding standards.
    • CI/CD pipelines needing pre-deployment validation.

• Build vs. Buy:

  • Buy: Avoid reinventing PHPStan rules for WordPress-specific edge cases (e.g., $wpdb queries, hooks, or theme template logic). This package provides out-of-the-box validation for:
    • WordPress core functions (e.g., get_post(), wp_insert_post()).
    • Hooks/filters (e.g., add_action(), apply_filters()).
    • Template files (e.g., the_content(), get_header()).
  • Build: Only if needing highly specialized rules (e.g., custom post type validation) not covered by this package.

• Use Cases:

  • Plugin/Theme Development: Catch type mismatches in REST API endpoints, ACF fields, or WooCommerce logic.
  • Legacy Code Modernization: Identify deprecated functions (e.g., get_the_author() vs. get_user_data()) or unsafe type casts.
  • Security Audits: Detect potential SQL injection risks in $wpdb queries or unsafe esc_* function usage.
  • Performance Optimization: Flag unused hooks or inefficient queries via static analysis.

When to Consider This Package

Adopt if:

• Your team uses WordPress + PHP and wants to reduce bugs without manual code reviews.
• You’re migrating from PHP 7.x to 8.x and need to validate type safety early.
• Your CI/CD pipeline lacks static analysis for WordPress-specific logic.
• You’re building plugins/themes with complex interactions (e.g., custom post types, REST APIs, or block editor integrations).
• Your codebase has high churn (e.g., frequent merges from contributors) and needs consistency.

Look elsewhere if:

• Your project is not WordPress-based (this package is WordPress-specific).
• You need dynamic analysis (e.g., runtime performance profiling) instead of static checks.
• Your team lacks PHPStan familiarity—consider starting with basic PHPStan before adding WordPress extensions.
• You’re constrained by legacy WordPress versions (e.g., <5.0) with minimal PHPStan support.
• You require custom business logic validation beyond WordPress core (may need bespoke rules).

How to Pitch It (Stakeholders)

For Executives: *"This package lets us catch WordPress-specific bugs before they reach production—saving dev time, reducing support costs, and improving our plugins/themes’ reliability. For example, it can:

• Block critical errors in custom post type queries or REST API endpoints.
• Enforce consistency across our WordPress codebase, reducing onboarding time for new hires.
• Integrate seamlessly with our CI/CD pipeline for zero-cost quality gates. Think of it as automated code review for WordPress, similar to how ESLint works for JavaScript. The investment is minimal (MIT-licensed, open-source), but the payoff is fewer fires, faster releases, and happier customers."*

For Engineering Teams: *"We’re adding PHPStan + WordPress extensions to our toolchain to:

1. Shift left on bugs: Catch type errors in $wpdb queries, hook callbacks, or template logic before testing.
2. Future-proof our code: Ensure compatibility with PHP 8.x+ and WordPress’s evolving standards.
3. Reduce technical debt: Automate checks for deprecated functions, unsafe casts, and unused hooks. How it works:

• Run phpstan analyse with the --extension=szepeviktor/phpstan-wordpress flag.
• Get actionable feedback on WordPress-specific edge cases (e.g., ‘This hook callback expects an array, but you’re passing a string’).
• Integrate with GitHub Actions or GitLab CI for automated enforcement. Effort: Low (5–10 hours to configure). Impact: High (fewer production incidents, cleaner PRs)."*
