//例子二：
//开始GET接口
//我们的空项目在首次运行后，会自动生成 index.php 这个文件，我们删除里面的内容，然后修改如下：?
$data = array(
'tid' => 100,
'name' => '标哥的技术博客',
'site' => 'www.huangyibiao.com');
$response = array(
'code' => 200,
'message' => 'success for request',
'data' => $data,
);
echojson_encode($response);
//我们这里的结构是日常App开发中最常见的返回数据结构了吧？通常都是状态码、状态信息和客户端业务数据。
//PHP其实也好给力，声明数组后，通过 json_encode 函数就可以输出json格式数据了！
//PHP POST接口
//假设我们要求传参数type过来，而且要求是数值型，用于返回不同的数据，当我们做接口测试时，就可以通过这么来干，就不需要等后台给接口了！
//
$type = $_POST['type'];
$data = '';
if (isset($type) && is_numeric($type) && $type >= 0) {
if ($type == 1) {
