PHP Parser Online

The PHP Parser Online tool provides static code analysis and parsing for PHP source files without executing them. It accepts raw PHP text or file contents, runs a formal grammar-based parser, and returns a structured representation such as an AST along with diagnostics. This helps developers validate syntax, understand code structure, and prepare refactoring plans. Conceptually, the tool tokenizes input, applies a PHP grammar, and emits nodes with type, location, and relationships that reflect PHP constructs like functions, classes, traits, and control structures. Unique value comes from version-aware parsing across PHP releases, enabling compatibility checks and targeted diagnostics. Core features include syntax error detection with precise location reporting, AST export in JSON, and a compact diagnostic summary suitable for CI pipelines. Use cases include pre-commit checks, code reviews, and onboarding new PHP codebases. The tool focuses on static structure rather than runtime behavior, making it suitable for quality gates and tooling integrations. Compared to simple linters, it offers a formal parse tree view and version-specific parsing behavior, which helps teams migrate between PHP versions with higher confidence.
