php encapsulates json communication interface

Detailed explanation of creating JSON data:


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


echo json_encode($arr);//This is the key function to create JSON
?>


Achieve results
{"id":1,"name":"david"}


Note: json_encode($value); this function can only receive UTF-8 encoded data. If data in other formats is passed to this function, null will be returned;


Encapsulate the data method of the communication interface
1. Communication data format standard:
0111 code status code (200,400) such as: 200 for successful login, 400 for unsuccessful login
message prompt message (email format is incorrect, 200 means login successful)
data return data
Example:


demo.php


class Response{
/**
*Output communication data in json format
*@param integer $code status code
*@param string $message prompt message
*@param array $data data
*return string The return value is json
*/
public static function json($code,$message='',$data=array()){


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