php封装json通信接口

创建JSON数据详解:


$arr=array(
'id'=>1,
'name'=>'david'
);


echo json_encode($arr);//这个是创建JSON的关键函数
?>


实现结果
{"id":1,"name":"david"}


注意: json_encode($value);这个函数只能接收utf-8编码的数据。其他格式数据传给该函数返回null;


封装通信接口的数据方法
1.通信数据格式标准:
0111 code 状态码(200,400)如:登录成功200,不成功400
message 提示信息(邮件格式不对,200代表登录成功)
data 返回数据
实例:


demo.php


class Response{
/**
*按json方式输出通信数据
*@param integer $code 状态码
*@param string $message 提示信息
*@param array $data 数据
*return string 返回值为json
*/
public static function json($code,$message='',$data=array()){


if(!is_numeric($code)){
return '';
}
$result=array(
'code'=>$code,
'message'=>$message,
'data'=>$data
);
echo json_encode($result);
exit;
}
