使用PHP来生成APP接口数据是非常简单的,如果你还不了解PHP没有关系,只需要看过PHP的基本语法,再看本示例就可以了。 

APP接口一般都是json格式(当然也有少数xml格式)遵循restful规范的:

    {
        code:200,
        msg:"这个是提示数据",
        data:[这里是数组数据]
    }

为了能立竿见影先看到效果,这里贴一个最简单最简单的一个demo代码
后面再贴一个基本完整的demo代码,带缓存和数据库查询的。先看简单的:
两个文件:一个封装了生成json的方法,一个是请求接口文件:

Response.php

<?php

 class Response{
    /**
     * @param $code 状态码
     * @param string $message  提示信息
     * @param array $data 数据
     * return string
     * 按json方式输出通信数据
     */
    public static function json($code,$message=&#39;&#39;,$data=array()){
        if(!is_numeric($code)){
            return &#39;&#39;;
        }
        $result = array(
          &#39;code&#39;=>$code,
          'message'=>$message,
            'data'=>$data
        );
        echo json_encode($result);
        exit;
    }
}

test.php

<?php
require_once(&#39;./Response.php&#39;);
$arr = array(
    &#39;id&#39; => 1,
    'name'=>'singwa'

);
Response::json(200,"数据返回成功",$arr);

两个文件,就完成了一个最简单的请求接口demo,现在测试一下,我本地安装了个PHPstudy,将这两个文件放在www根目录里,浏览器输入接口地址

http://localhost/test.php
