}

$sun = new sun();  
$reflect=new ReflectionClass($sun);

//ReflectionObject 继承了ReflectionClass
$props=$reflect->getProperties(); //获取类属性
foreach ($props as $prop=>$value)
{
    print $value->getName()."\n";
}
$method=$reflect->getMethods(); //获取方法
foreach ($method as $key=>$value)
{
    print $value->getName()."\n";
} 

输出:

父类构造函数
子类构造函数
