Question

我有JSON值，存储在php变量$ string

中

    $string= '{
    "SUCCESS": [
        {
            "MESSAGE": "IMEI Service List",
            "LIST": {
                "Cable": "This is cable1",
                "Cable servers and log": {
                    "GROUPNAME": "Cable servers and log",
                    "SERVICES": {
                        "110": {
                            "SERVICEID": 995,
                            "TIME": " Minutes",
                            "Requires.MEP": "None",
                            "Requires.PRD": "None"
                        }
                    }
                }
            }
        }
    ]
}';

我在php中访问这些JSON值时出现问题

对于php代码我使用了这段代码：

$json_a=json_decode($string,true);

foreach($json_a[SUCCESS] as $p)
{
echo 'Message: '.$p[MESSAGE]. '</br>';
}

上面的PHP代码很好但我不知道如何显示的值 php中的“GROUPNAME”和“SERVICEID”

Answer 1

$data=json_decode($string,true);


foreach ($data["SUCCESS"] as $loopdata)
{
//spaces occur in json key cable servers and log
   echo $loopdata["LIST"]["Cable servers and log"]["GROUPNAME"];
}

注意：您的json无效。以下是有效的

$string={
    "SUCCESS": [
        {
            "MESSAGE": "IMEI Service List",
            "LIST": {
                "Cable": "This is cable1",
                "Cable servers and log": {
                    "GROUPNAME": "Cable servers and log",
                    "SERVICES": {
                        "110": {
                            "SERVICEID": 995,
                            "TIME": " Minutes",
                            "Requires.MEP": "None",
                            "Requires.PRD": "None"
                        }
                    }
                }
            }
        }
    ]
}

Answer 2

首先引用带有' or " ['text']良好做法的assos数组键，有时键有空格，例如[Cable servers and log]，然后没有引号致命错误

解析错误：语法错误，意外的＆＃39;服务器＆＃39; （T_STRING），期待＆＃39;]＆＃39;

你可以通过这种方式获得＆＃34; GROUPNAME＆＃34; 尝试此代码

foreach($json_a['SUCCESS'] as $p)
{
   echo 'Message: '.$p['MESSAGE']. '</br>';
   echo 'GROUPNAME: '.$p['LIST']['Cable servers and log']['GROUPNAME']. '</br>';
}
