How php receives json

$.ajax({       cache: true,        type: "POST",        url:"/index.php/Article/index",           data:{name:$("#name").val()},        async: false,       datatype: "json",        error: function(request) {            alert("Connection error");        },      success: function(data) {                       }    });

Firebug: name = % E7 % AC % E4 % B8 % 80% E8 % BD % AE. I want to know how to get the name in the php background, and output to the foreground page

Reply to discussion (solution)

Echo $ _ POST ['name'];

Echo $ _ POST ['name'];

The output is NULL or I don't need to post any more ..

What you see is not name = % E7 % AC % E4 % B8 % 80% E8 % BD % AE
Name = first round

What you see is not name = % E7 % AC % E4 % B8 % 80% E8 % BD % AE
Name = first round

You can parse it all. it's so fierce. yesterday I didn't use json. today I tried to use json for transmission. I started to think too much. I thought I had to parse it with json_decode and then output it.

You can mix it yourself. datatype: "json" indicates that the returned results are parsed in json format.
So you cannot simply echo $ _ POST ['name '];

What you see is not name = % E7 % AC % E4 % B8 % 80% E8 % BD % AE
Name = first round
