This article mainly introduces the PHP encapsulation JSON communication interface details and examples of relevant information, the need for friends can refer to the following

PHP creates JSON data in a detailed detail:

<?php  //Create an array of characters $arr =array (   ' id ' =>1,   ' name ' = ' David ');   echo Json_encode ($arr);//This is the key function to create JSON?>

{"id": 1, "name": "David"}

Note: Json_encode ($value); This function can only receive UTF-8 encoded data. Other format data is passed to the function to return null;

Data methods for encapsulating communication interfaces

1. Communication Data Format standard:
0111 Code Status Code (200,400) such as: Logon success 200, unsuccessful 400
Message hint message (message format is incorrect, 200 for login success)
Data returned

Instance:

demo.php

<?php   class response{/** * Output Communication data as JSON * @param integer $code Status code * @param string $message message * @param array $data Data *return string return value is JSON///static method, constructs JSON data public static function JSON ($code, $message = ", $data =array ()) {    if (!is_ Numeric ($code)) {    return ';    }   $result =array (   ' Code ' = $code,   ' message ' = $message,   ' data ' = $data    ); Echo Json_encode ($ result); Exit;   } }?>
