## Description

This tool is a command-line utility designed to automatically detect and correct coding standard violations in PHP source files. It functions as a static analysis and refactoring engine that ensures consistent project-wide formatting by applying predefined community conventions or custom organizational rules.

The project distinguishes itself through a modular rule-based engine that supports both automated style correction and codebase modernization. It allows developers to update legacy syntax to align with newer language versions and testing framework requirements, facilitating the adoption of modern features across existing projects.

The tool provides extensive configuration options for defining file scope, formatting whitespace, and custom rule sets. It supports high-performance workflows through incremental execution caching and parallel task distribution, which significantly reduce processing time on large codebases. Furthermore, it integrates into continuous integration pipelines and development environments to provide automated validation and real-time style enforcement.

Users can manage these processes via a comprehensive command-line interface that includes features for describing rule behavior and exporting machine-readable analysis reports.
