//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) {

$data = array(

'type' => $type,

} else if ($type == 2) {

$data = array(

}

$response = array(

'code'  => 200,
