The record

Purpose: phpcpd-next is a token-based copy/paste detector for PHP 8.4+ and a successor to Sebastian Bergmann’s phpcpd.
Detection: Its default run combines Rabin-Karp exact matching with TokenBag detection of reordered code; an opt-in unified engine detects exact, renamed, gapped, and reordered clones.
Orphan detection: The optional --orphans mode finds unreferenced classes, interfaces, traits, enums, and functions.
Reports: It provides console, PMD-CPD XML, JSON, and SARIF 2.1.0 output formats.
CI use: Meaningful exit codes, result caching, and a per-file incremental index support CI use; clone findings produce exit status 1.
Integrations: The project documents PHPUnit integration, an in-process headless API, framework presets, and SARIF upload to GitHub Code Scanning.
Requirements: It requires PHP 8.4+, ext-dom, and ext-mbstring, and lists zero Composer runtime dependencies.
Setup: The documented installation is as a Composer development dependency, as a global Composer package, or from source.
License: The project states that phpcpd-next is licensed under MIT.
Limit: research engines: The README describes advanced engines as opt-in and research-grade, with higher false-positive rates on real-world code than the default set.
Limit: design repetition: The README says the duplicated-line percentage measures copied tokens and cannot substitute for reviewing structural repetition in code design.
Support: The opened project page describes contribution guidance and a Contributor License Agreement; it does not state a paid support plan.
