Php 如何处理多维数组的数组

下面的数组包含数组和数组。这只是一个条目；想象一下，现在我有20个源，每个源至少包含10个条目，如下所示。这是我想解决的噩梦

有谁能给我一些建议，告诉我如何在PHP中高效地解析这些内容，并能够获取每个值，以便能够将它们插入到数据库中进行进一步处理！！多谢各位

如果数组中始终存在相同的键，则使用如下内容进行迭代应该相对容易：

foreach($yourarray as $key1=>$item1){
  //dosomething
  if($key1=="alternate"){
     foreach($item1 as $key2=>$item2){
        //and so on
     }
  }

}

至于将其保存到数据库中，我承认这并不容易，而且我对数据库没有太多的经验，但如果我是你，我会将它们保存在多个表中，并带有1到n个引用。

首先，我想感谢你的建议：我尝试过，效果不错，但随着我的进步，我最终得到了3个或更多的foreach。我最后还不得不检查键和值，因为我肯定不想存储所有东西，比如URL、标题、PulblishedDate、图像URL，也许还有摘要。然而，在循环中搜索这些值有点累人，你不觉得吗？！
