从AgileCRM提供的多维数组中获取特定值

Question

我试图从AgileCRM获得第一笔交易ID。

使用时：

$test = json_decode($deal, true);
print_r($test);

我得到以下结果：

)

我想回应＆＃34; 5686812383117312＆＃34;来自＆＃34; [id] =＆gt; 5686812383117312＆＃34; （上面数组中的第4行）

我已经尝试过＆＃34; foreach＆＃34;声明，但我对它的专业知识是有限的，似乎无法做到正确。

任何帮助将不胜感激。

要访问ID字段，您应该：

1. 获取阵列的第一把钥匙
2. 访问必填字段

阵列：

select INPUT__FILE__NAME from table

PHP：

Array ( //$test
  [0] => Array (  //first key [0] 
      [colorName] => WHITE 
      [id] => 5686812383117312  //the required field ['id']
      [apply_discount] =>
