如何使用PHP获取数组中的确切键值？

Question

这是我的代码

$response = json_decode($result);
print_r($response);

我得到了结果

  stdClass Object ( [type] => http://developer.mailchimp.com/documentation/mailchimp/guides/error-glossary/ [title] => Resource Not Found 
[status] => 404 
[detail] => The requested resource could not be found. 
[instance] => ) 

我加了

foreach($response as $key=>$val)
{
    echo $key.'='.$val.'<br>';
}

但我想知道如何获得detail的确切密钥和值。怎么弄？ 感谢

Answer 1

foreach($response as $key => $val){
  echo "Key: " . $key . "Value: " . $val->detail;
}

Answer 2

json_decode（）中存在问题，您必须传递2参数＆＃34; true＆＃34;，就像这样..

$response = json_decode($result,true);
print_r($response);
