如何将JSON数据解析为PHP？ [关闭]

I am new to PHP and AngularJS. I want to get JSON data.

Chrome shows the data I post

{"sessionName":"1","computer":"2","quality":{"name":"LAN(very fast)"}}

I know that if I want to get sesstionName, it's:

$value = json_decode(file_get_contents('php://input'));
echo $value->sessionName;

How can I get quality value from PHP?

You need to access like this

echo $value->quality->name;

Eventually if you prefer to work with arrays instead of objects, my advice is to do:

$value = json_decode(file_get_contents('php://input'),true);

then you can see the result:

print_r($value['quality']);
