如何利用php 来反射API获取类信息

$ref = new ReflectionClass($classname);echo $ref->getName();echo $ref->getFileName();

$ref = new ReflectionClass($classname);$properties = $ref->getProperties();foreach($properties as $property){    echo $property->getName();
}

$ref = new ReflectionClass($classname);$methods = $ref->getMethods();foreach($methods as $method){    echo $method->getName();
}

$ref = new ReflectionClass($classname);$interfaces = $ref->getInterfaces();foreach($interfaces as $interface){    echo $interface->getName();
}

<?php/** 用户接口 */interface IUser{    // 新增用户
    public function add($data);    // 读取用户数据
    public function get($id);

}/** 用户类 */class User implements IUser{    /** 
      * 用户数据
      */
    protected $user = array();    /**

        $this->user[] = $data;
        $keys = array_keys($this->user);        return end($keys);

        }else{            return array();
        }
    }
