我想在一个单独的变量中获取最后的发货状态。我用了这段代码

$status = $data[0]['ProcessDescForPortal'];

但它返回结果的第一个状态，例如“CONSIGNMENT BOOKED”，但我想保存最后一个状态“DELIVERED”。实际上，我想获取跟踪的最后状态。

如何做到这一点？

问候

【问题讨论】：

您可以使用end(json_decode($data)) PHP 函数来做到这一点。
与查看任何数组中最后一个条目的方式相同，假设您对 JSON 字符串执行了 json_decode()`

标签： php html json

【解决方案1】：

您必须使用 json_decode() 将其转换为数组然后选择数组并指向对象。

这是工作代码

【解决方案2】：

谢谢大家，我找到答案了

end($data)['ProcessDescForPortal'];

问候。

【讨论】：

是的 :) @RobinSingh 谢谢 :)
如果“ProcessDescForPortal”的位置发生变化，您不会注意到它。所以你必须使用我的方法或madalinivascu 的方法。 PS没关系
其实@HannahJames 说他/她想得到 ['ProcessDescForPortal'] 的最后一个元素，不需要检查它是否交付，它的值不重要，但位置。跨度>
@Jerson 是的 :) 但是谢谢大家和 StackOverflow 的快速响应 :)

【解决方案3】：

使用map函数只返回状态，使用end函数返回最后状态

$data = json_decode($data,true);
$data = array_map($data,function($row) {
   return $row['ProcessDescForPortal'];
});
var_dump(end($data));

【讨论】：

其实我想获取最后的跟踪状态['ProcessDescForPortal']

【解决方案4】：

你有两个选择。

数组始终按TransactionDate 属性升序排列。然后你只需要取出数组中的最后一项。

$arr = json_decode($data);
$last = end($arr);
$ProcessDescForPortal = $last->ProcessDescForPortal;

数组不是强制排序的。然后您需要先对数组进行排序，然后再使用最新的。

$arr = json_decode($data);
usort($arr, function($a, $b){
    return strcmp($a->TransactionDate, $b->TransactionDate);
});
