【问题描述】：

谁能告诉我如何回显或使用嵌套键值。我基本上 get() 这个集合，我正在使用 foreach 做一些进一步的计算。 我的关系结构是 zone.shipping，在这里我想从巢中获取燃料和紧急情况。

["id":614,"weight":"25.000","rate":"150.640","unit":"kg","detail":"normal","zone":"id":5,"zone":"e","company":1,"shipping":"id":1,"company":"fedex","fuel":"19.50","emergency":"1.35","source":1,

"id":1838,"weight":"25.000","rate":"179.610","unit":"kg","detail":"normal","zone":"id":17,"zone":"7","company":2,"shipping":"id":2,"company":"dhl","fuel":"19.75","emergency":"0.50","source":1,

"id":2414,"weight":"25.000","rate":"263.320","unit":"kg","detail":"normal","zone":"id":24,"zone":"6","company":3,"shipping":"id":3,"company":"ups","fuel":"24.00","emergency":"1.30","source":1]

【参考方案1】：

将您的数组放入我刚才作为参考的一个变量中

$data = ["id":614,"weight":"25.000","rate":"150.640","unit":"kg","detail":"normal","zone":"id":5,"zone":"e","company":1,"shipping":"id":1,"company":"fedex","fuel":"19.50","emergency":"1.35","source":1,

"id":1838,"weight":"25.000","rate":"179.610","unit":"kg","detail":"normal","zone":"id":17,"zone":"7","company":2,"shipping":"id":2,"company":"dhl","fuel":"19.75","emergency":"0.50","source":1,

"id":2414,"weight":"25.000","rate":"263.320","unit":"kg","detail":"normal","zone":"id":24,"zone":"6","company":3,"shipping":"id":3,"company":"ups","fuel":"24.00","emergency":"1.30","source":1];

获取值

foreach($data as $key => $value)

   $fuel[] = $value['zone']['shipping']['fuel'];
   $emergency[] = $value['zone']['shipping']['emergency'];

获得燃料和紧急情况的主要方法是

$value['zone']['shipping']['fuel'];
$value['zone']['shipping']['emergency'];

对于具体的索引，你也可以得到：

$data[0]['zone']['shipping']['fuel'];
$data[0]['zone']['shipping']['emergency'];

【讨论】：

这看起来不错。我很快就会试一试。现在我这样做了，它已经奏效了 $fuel = $rate->zone()->first()->shipping()->first()->fuel; $emergency = $rate->zone()->first()->shipping()->first()->emergency;

【参考方案2】：

您正在寻找data_get()
