PHP はリフレクションを使用してクラスといくつかの基本的なアプリケーションを取得します

class A
{
    private $_foo = 'this is a';
    public function index()
    {
        return $this->_foo;
    }
    private function _come($param)
    {
        return 'this is come'.$param;
    }

}
$refClass = new ReflectionClass('A');//获得反射

$privateParams = $refClass->getDefaultProperties();
print_r($privateParams);//得到结果 Array ( [_foo] => this is a )
echo $privateParams['_foo'];//得到 this is a

/****************获得类的实例*******************/
$class = $refClass->newInstance();
echo $class->index();

/****************获取A的方法*******************/
$refHasClass = $refClass->getMethods();
print_r($refHasClass);
/***
 * Array ( [0] => ReflectionMethod Object ( [name] => index [class] => A )
 * [1] => ReflectionMethod Object ( [name] => _come [class] => A ) )
 */
$come = $refClass->getMethod('_come');
$come->setAccessible(true);
echo $come->invoke($class,'this is param');
// this is athis is comethis is param
