50 Alternatives to PHPQA
Analyzer of PHP code to search issues with deprecated functionality in newer interpreter versions. It finds removed objects (functions, variables, constants and ini-directives), deprecated functions functionality, and usage of forbidden names or tricks (e.g. reserved identifiers in newer versions).
Instant Upgrades and Automated Refactoring of any PHP 5.3+ code. It upgrades your code for PHP 7.4, 8.0 and beyond. Rector promises a low false-positive rate because it looks for narrowly defined AST (abstract syntax tree) patterns. The main use-case are tackling technical debt in your legacy code and removing dead code. Rector provides a set of special rules for Symfony, Doctrine, PHPUnit, and many more.

Emerge is a source code and dependency visualizer that can be used to gather insights about source code structure, metrics, dependencies and complexity of software projects. After scanning the source code of a project it provides you an interactive web interface to explore and analyze your project by using graph structures.
Regexp based customizable linter.
Grep rough audit - source code auditing tool.
Lizard is an extensible Cyclomatic Complexity Analyzer for many programming languages including C/C++ (doesn't require all the header files or Java imports). It also does copy-paste detection (code clone detection/code duplicate detection) and many other forms of static code analysis. Counts lines of code without comments, CCN (cyclomatic complexity number), token count of functions, parameter count of functions.

A framework for managing and maintaining multi-language pre-commit hooks.
A static source code analyser for vulnerabilities in PHP scripts.
A fast, open-source, static analysis tool for finding bugs and enforcing code standards at editor, commit, and CI time. Its rules look like the code you already write; no abstract syntax trees or regex wrestling. Supports 17+ languages.
Scan is a free open-source DevSecOps platform for detecting security issues in source code and dependencies. It supports a broad range of languages and CI/CD pipelines.
Static program analysis platform that allows custom analyzers to plug in through a common interface.
Sigrid helps you to improve your software by measuring your system's code quality, and then compares the results against a benchmark of thousands of industry systems to give you concrete advice on areas where you can improve.
Suite of static analysis tools consisting of the three components Sotoarc (Architecture Analysis), Sotograph (Quality Analysis), and Sotoreport (Quality report). Helps find differences between architecture and implementation, interface violations (e.g. external access of private parts of subsystems, detection of all classes, files, packages and subsystems which are strongly coupled by cyclical relationships and more. The Sotograph product family runs on Windows and Linux.
