通过foreach循环将值传递给数组，然后在第一个数组结果中是可以的，但是在第二个，第三个等等中它重复数组之前的值，就像在数组第二个中一样，它首先重复数组的值，在第三个数组中它重复第二个的数组值。我怎样才能解决这个问题？

这是我将值传递给数组的方法：

   <?php

//
$item_holder = array();
$item_feature_holder = array();
$item_shipping_holder = array();
$item_imagesets_holder = array();

    //Get items from amazon
    foreach($response->Items->Item as $item){
        //Display item features
        if(isset($item->ItemAttributes->Feature)){
            if(is_array($item->ItemAttributes->Feature)){
                foreach($item->ItemAttributes->Feature as $itemFeature){
                    echo '<p>'.$itemFeature.'</p>';
                    $item_feature_holder[] = $itemFeature;
                }
            }
            else{
                echo '<p>'.$item->ItemAttributes->Feature.'</p>';
            }
        }

        //Display more images
        foreach($item->ImageSets->ImageSet as $moreImage){
            if(isset($moreImage->ThumbnailImage)){
                $item_imagesets_holder[] = $moreImage->SmallImage->URL;
            }
        }

        $item_shipping_holder = array(
        'standard'=>$standard_shipping, 
        'expedited'=>$expedited_shipping, 
        'twoday'=>$twoday_shipping, 
        'oneday'=>$oneday_shipping);

        $item_holder[] = array(
        'default_image'=>$item_image_medium, 
        'category'=>$item->ItemAttributes->ProductGroup, 
        'title'=>$item->ItemAttributes->Title, 
        'asin'=>$item->ASIN, 
        'weight'=>$rounded_weight, 
        'description'=>$product_description, 
        'features'=>$item_feature_holder, 
        'shipping'=>$item_shipping_holder, 
        'image'=>$item_imagesets_holder);

    }

在我的转储中，第一个数组没问题，但在我的第二个数组中，在特征和图像部分它重复了第一个数组的数据。

这是我的数组的 var_dump：

尝试在 for 循环的每次迭代期间重置持有者数组

foreach($response->Items->Item as $item){
  $item_feature_holder   = array();
  $item_imagesets_holder = array();
  // rest of your code

你的代码是一团糟。你应该重写它。

$item_holder = [];
$item_shipping_holder = [];

function getItemFeatures($itemAttributes)
{
    if (!isset($itemAttributes->Feature))
        return [];

    return (array) $itemAttributes->Features;
}

function getItemImages($imageSets)
{
    $result = [];
    foreach($imageSets->ImageSet as $moreImage)
    {
        if(isset($moreImage->ThumbnailImage))
        {
            $result[] = $moreImage->SmallImage->URL;
        }
    }

    return $result;
}

   //Get items from amazon
foreach($response->Items->Item as $item)
{
    $features = getItemFeatures($response->itemAttributes);
    // Display item features.
    foreach ($features as $feature)
    {
        echo "<p>{$feature}</p>";
    }

    $item_shipping_holder = [
    'standard' => $standard_shipping, 
    'expedited' => $expedited_shipping, 
    'twoday' => $twoday_shipping, 
    'oneday' => $oneday_shipping
    ];

    $item_holder[] = [
    'default_image' => $item_image_medium, 
    'category' => $item->ItemAttributes->ProductGroup, 
    'title' => $item->ItemAttributes->Title, 
    'asin' => $item->ASIN, 
    'weight' => $rounded_weight, 
    'description' => $product_description, 
    'features' => $features, 
    'shipping' => $item_shipping_holder, 
    'image' => getItemImages($item->ImageSets)
    ];
}
