Question

I am retrieving data via JSON and PHP from a URL. I am having difficulty breaking the object apart and displaying the data. The PHP code seems to be working until I get to the for loops.

$jsonurl =  http://myweb/api.php ;
$json = file_get_contents($jsonurl);
$json_output = json_decode($json);
foreach ($json_output->Monitoring AS $monitoring) {
    foreach ($monitoring->Status AS $Status){
        echo $Status->Emailed;
        echo $Status->Status;
    }

我的数据结构如下:

 object(stdClass)#12 (1) 
      { ["Monitoring"]=> array(10) { [0]=> object(stdClass)#13 (14) 
            { 
            ["Status"]=> string(30) "HTTP/1.1 302 Moved Temporarily"
            ["Emailed"]=> string(1) "0" } 
            [1]=> object(stdClass)#14 (14) { 
            ["Status"]=> string(30) "HTTP/1.1 302 Moved Temporarily" 
            ["Emailed"]=> string(1) "0" } 
            [2]=> object(stdClass)#15 (14) { 
            ["Status"]=> string(30) "HTTP/1.1 302 Moved Temporarily" 
            ["Emailed"]=> string(1) "0" } 
            [3]=> object(stdClass)#16 (14) { 
            ["Status"]=> string(30) "HTTP/1.1 302 Moved Temporarily"               
            ["Emailed"]=> string(1) "0" }
            } }

Answer 1

根据你所描述的数据结构,你只需要一个 for,例如:

$jsonurl =  http://myweb/api.php ;
$json = file_get_contents($jsonurl);
$json_output = json_decode($json);
foreach ($json_output->Monitoring AS $Status) {
    echo $Status->Emailed;
    echo $Status->Status;
}

First of all, are you sure your script returns actual JSON string? Did you json_encode it?

您是否比较了在JSON和脱硫之后的物体数据结构? 是否有任何分歧? 也许这根本不是关于每个游乐场和初等动物的问题,而是属于你们的数据结构,而这种结构似乎包括多个次级目标。

Alternative is to try and use associative arrays instead of objects in that context by returning json_decode($json,true) and treating it as an array.

首先,确保你纠正错误报告,以便你能够看到究竟是失败了。

转至<代码>json_decode的不当格式将只是退回错误。这是PHP s json处理工作的一个限制,他们试图通过创建<代码>JSONSerializable接口在下一期发行时处理。确保回归代码为<代码>stdClass(或如果你通过联系阵列的选择,则阵列永远不会执行。
