Let’s first introduce the Json encapsulation method

If the json_encode function passes Chinese, the output will be garbled. , I think it is necessary to make an explanation for this problem:

In fact, json_encode is not garbled for Chinese, but json_encode will convert Chinese into unicode encoding, so the output will be this encoding, but it does not affect our use. We After json_decode, it will be a normal value, but if you want to output json_encode in Chinese, there is actually a way, as follows:

echo urldecode(json_encode(urlencode("JSON Chinese output solution")) ; Many only have this function;

But in terms of readability, XML looks more intuitive, while Json looks messy and time-consuming;

The above is Json below Let’s get an XML one!

Method: PHP generates XML data;

How to generate XML data?

The following two methods can be achieved--> 1. Assemble into an XML string 2. Use system classes such as: DomDocument, XMLWriter, SimpleXML

Go to the Demo directly first!

<?php  
  
//服务端 json.php  
//php中用数组表示JSON格式数据  
header("Content-type:text/html;charset=utf-8");  
$arr = array(    
    &#39;code&#39; => 200,  
    &#39;message&#39; => &#39;数据返回成功&#39;,  
    &#39;data&#39; => array(    
        &#39;name&#39; =>&#39;bawei&#39;,    
        &#39;email&#39; =>&#39;www.bawei@qq,com&#39;,    
    ),  
);   
echo json_encode($arr); //将数组封闭成JSON数据 主要函数json_encode;  
?>
