给你：

<?php
$data = json_decode(file_get_contents('https://api.spacexdata.com/v3/launches/past'), true);
foreach($data as $entry) {
   if($entry['launch_year'] === '2017') {
      if(isset($entry['rocket']['second_stage']['payloads'])) {
         foreach($entry['rocket']['second_stage']['payloads'] as $payload) {
            foreach($payload['customers'] as $customer) {
               if($customer === 'DARPA') print_r($entry);
            }
         }
      }
   }
}

你需要自己添加一些错误处理。代码可以工作，但2017年没有DARPA客户。如果你检查2006年，它会找到它。
