基于PHP数组同一行中的另一个键值检索键值

$result =   Array(
  [0] => Array([storepickup_id] => 3[sku] => 691294[inventory] => 33[reserve] => )
  [1] => Array([storepickup_id] => 3[sku] => 692284[inventory] => 3[reserve] => )
  [2] => Array([storepickup_id] => 3[sku] => 692289[inventory] => 4[reserve] => )
  [3] => Array([storepickup_id] => 3[sku] => 693510[inventory] => 8[reserve] => )
  [4] => Array([storepickup_id] => 3[sku] => 150893[inventory] => 2[reserve] => )
  [5] => Array([storepickup_id] => 3[sku] => 150906[inventory] => 4[reserve] => )
)

我试图用一个为每个语句预先构建的数组来过滤上述数组,如下所示:

<?php foreach ($_productCollection as $_product): ?>
    <?php
    echo "SKU: " . $_product->getSku();
    echo "INVENTORY: " . array_column($result, 'inventory', $_product->getSku());
<?php endforeach; ?>

因此,如果$_product-getSku()生成691294,我想从PHP数组的同一索引/行中检索相应的“inventory”值。

<?php foreach ($_productCollection as $_product): ?>
  <?php
  function my_function($item_values)
  {
      if ($item_values = $_product->getSku())
      {
          return true;
      }
      return false;
  }
  $sku = $_product->getSku();
  print_r(array_filter($sku,"my_function"));
  ?>
<?php endforeach; ?>

在处理上述多维数组时,有更好的方法吗?提前谢谢。
