A transparent AOP library for PHP.

What is Mimic?

PHP-Mimic is a transparent AOP (Aspect-Oriented Programming) framework that intercepts class loading at the stream level. It reshapes code on-the-fly via AST (Abstract Syntax Tree) manipulation, enabling non-intrusive logic injection into any class—including final classes and methods—without modifying original source files or requiring manual proxies.

Core Philosophy

Transparent: Works with native new, static, and instanceof calls.
Intrusive but Safe: Capability to intercept final members and private scopes.
Debug-First: Integrated source-mapping ensures stack traces and error reports point back to original file paths and line numbers.
Zero Eval: No eval() is used. All code is processed via custom stream wrappers and the Zend OPcache.

Installation

composer require wheakerd/php-mimic

Quick Start

1. Initialize the Kernel

$mimic = new MimicFactory();

$mimic->register(
    [
        TestCaseService::class => $composerLoader->findFile(TestCaseService::class),
    ],
)->intercept([TestCaseService::class, 'handle'], function (ProceedingJoinPoint $point) {
    var_dump('Print return value：' . $point->proceed());

    return 999;
});

// Direct your autoloader to use the aop:// prefix
