$obj = json_decode($json);
echo $obj->{'dg_j'};
echo '<br>';
echo $obj->{'dg_sh'};
推荐答案
实际上，您得到的是一个包含单个对象的数组.你想要
What you've got is actually an array that contains a single object. You'd want
$obj[0]->dg_j
执行var_dump($obj)将显示JSON实际变成了什么.
Doing a var_dump($obj) will show you what the JSON actually turned into.
