Question

这是我的php代码 [EDITED] ：

$redis_data =  file_get_contents("http://example.org/data/data.txt");

该代码返回以下json数据：

{"Phone":"08XXXXX","StartTime":"121212","Customer":"Customer A","time":1407921302}
{"Phone":"08XXXXX0","StartTime":"111111","Customer":"Customer B","time":1407921302
{"Phone":"08XXXXX","StartTime":"131313","Customer":"Customer C","time":1407921302}

这是我循环解析值的代码：

$redis_data =  file_get_contents("http://example.org/data/data.txt");
$redis_data = json_decode($redis_data, true);

foreach ($redis_data as $data) {
    echo $data['Phone'];
    echo "<br>";
}

但我得到了这个错误：

Invalid argument supplied for foreach()

我做错了什么？

Answer 1

您尝试获取的数据格式不正确json

[{"firstName":"John", "lastName":"Doe"}, 
{"firstName":"Anna", "lastName":"Smith"}, 
{"firstName":"Peter", "lastName": "Jones"}]

这是json语法。并且您将获得以下格式的数据。

{"ANumber":"08122378673","BNumber":"500046","StartTime":"08122014102113","EndTime":"08122014104126","TrunkA":"S1JK2SBD1S","TrunkB":"N7JK2GSM1B","Customer":"PT.BNI","time":1407921302} {"ANumber":"081351607600","BNumber":"14000","StartTime":"08122014102406","EndTime":"08122014103738","TrunkA":"S1JK2SSB1S","TrunkB":"EPJK2MNR0","Customer":"Bank Mandiri (CC_IB_Jasnita)","time":1407921302}

您可能需要重新格式化数据字符串

Answer 2

你试图循环JSON - 而不是PHP。在尝试循环之前，您需要在json_decode变量上运行$redis_data（docs）。

$redis_data = json_decode($redis_data, true);

Answer 3

你需要解码json才能循环播放它。

$redis_data =  json_decode(file_get_contents("http://example.com/tes_files/data.txt"), true);

foreach ($redis_data as $data) {
   echo $data['phone'];
}

Answer 4

这是解决方案

$redis_data =  explode( chr(10), file_get_contents("http://example.com/tes_redis/data.txt"));

foreach ($redis_data as $data) { 
    var_dump(json_decode($data));
     $data = json_decode($data);
     echo $data->Phone;
     echo $data->StartTime;
     echo $data->Customer;
     //echo $data->ANumber;
     //echo $data->BNumber;
}

您需要先导出数据。

首先你必须使用 json_decode 函数将json转换为数组，它将给出数组，之后你可以循环

  `
     $jsonString =
    '[{"Phone":"08XXXXX","StartTime":"121212","Customer":"Customer A","time":1407921302},
    {"Phone":"08XXXXX0","StartTime":"111111","Customer":"Customer B","time":1407921302},
    {"Phone":"08XXXXX","StartTime":"131313","Customer":"Customer C","time":1407921302} ]';
    $array=json_decode($jsonString);

    foreach ($arrayOfEmails as $data) {
       echo $data->Phone."<br>";
    }

`
