PHP Code Analyzer

The tool analyzes PHP source code statically to identify syntax errors, undefined variables, deprecated functions, and risky constructs. It does not execute code and does not require a PHP runtime. Analysts and developers use it during writing, code reviews, and CI checks to gain early feedback on code quality and maintainability. By focusing on patterns that commonly cause bugs in PHP projects, it reduces time spent on manual code inspection and accelerates quality gates.\n\nThe core inference engine builds a lightweight abstract syntax tree (AST) from the PHP input, then applies a configurable rule set. It flags issues with severity levels, generates concise messages, and suggests concrete fixes or refactors. Advanced mode enables PHP-version-aware checks, complexity estimation, and batch processing across multiple files. The tool outputs structured results suitable for automated pipelines and for developers to triage findings quickly.\n\nDistinctive value comes from its offline capability, clarity of findings, and integrable outputs for CI/CD. It supports common PHP versions, aligns with typical development workflows, and provides actionable guidance rather than vague warnings. Use cases include vetting legacy code, pre-commit checks, code-review preparation, and onboarding new PHP developers to consistent standards. It complements runtime testing by catching issues the interpreter may not surface in isolation. Unique differentiators include AST-based detection, no runtime execution, and exportable JSON for automation.
