我正在使用类似于此结构的索引PHP数组:
$result = Array(
[0] => Array([storepickup_id] => 3[sku] => 691294[inventory] => 33[reserve] => )
[1] => Array([storepickup_id] => 3[sku] => 692284[inventory] => 3[reserve] => )
[2] => Array([storepickup_id] => 3[sku] => 692289[inventory] => 4[reserve] => )
[3] => Array([storepickup_id] => 3[sku] => 693510[inventory] => 8[reserve] => )
[4] => Array([storepickup_id] => 3[sku] => 150893[inventory] => 2[reserve] => )
[5] => Array([storepickup_id] => 3[sku] => 150906[inventory] => 4[reserve] => )
)
我试图使用预先构建的FOR EACH语句过滤上面的数组,如下所示:
<?php foreach ($_productCollection as $_product): ?>
<?php
echo "SKU: " . $_product->getSku();
echo "INVENTORY: " . array_column($result, 'inventory', $_product->getSku());
<?php endforeach; ?>
因此,如果$ _product-getSku()得到691294,我想从PHP数组的相同索引/行中检索相应的“inventory”值。
FOR EACH中的上述array_column不起作用。我还尝试了一个基于array_filter的函数,它无法产生正确的结果:
<?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; ?>
使用上面的多维数组时是否有更好的方法?提前谢谢。

首先,您需要创建一个新数组,其索引/键包含sku,列/值包含来自$ result数组的库存。
$new_array = array_column($result, 'inventory', 'sku');
然后在循环中使用新数组
<?php foreach ($_productCollection as $_product): ?>
<?php
echo "SKU: " . $_product->getSku();
echo "INVENTORY: " . $new_array[$_product->getSku()];
<?php endforeach; ?>
如果$ _product-getSku()得到691294,则Invetory将为33

function getIndex($needle, $haystack, $array){
foreach($array as $key => $value){
if(is_array($value) && $value[$haystack] == $needle)
return $key;
}
return null;
}
像这样使用:
$i = getIndex(691294, 'Sku', $array);
echo $array[$i]['inventory'];
