软件简介

Go! 是一个 PHP 5.4 库，让 PHP 支持 AOP 面向方面编程方法，无需 PECL 扩展、Runkit、evals 或者 DI 容器支持。可使用
XDebug 轻松调试。

示例代码：

// Aspect/MonitorAspect.php

namespace Aspect;

use Go\Aop\Aspect;
use Go\Aop\Intercept\FieldAccess;
use Go\Aop\Intercept\MethodInvocation;
use Go\Lang\Annotation\After;
use Go\Lang\Annotation\Before;
use Go\Lang\Annotation\Around;
use Go\Lang\Annotation\Pointcut;

/**
 * Monitor aspect
 */
class MonitorAspect implements Aspect
{

    /**
     * Method that will be called before real method
     *
     * @param MethodInvocation $invocation Invocation
     * @Before("execution(public Example->*(*))")
     */
    public function beforeMethodExecution(MethodInvocation $invocation)
    {
        $obj = $invocation->getThis();
        echo 'Calling Before Interceptor for method: ',
             is_object($obj) ? get_class($obj) : $obj,
             $invocation->getMethod()->isStatic() ? '::' : '->',
             $invocation->getMethod()->getName(),
             '()',
             ' with arguments: ',
             json_encode($invocation->getArguments()),
             "<br>\n";
    }
}
