Question

通过foreach循环将值传递给数组然后在第一个数组结果中是正常的但是在第二个，第三个等等它重复数组之前的值，就像在数组中一样，它重复第一个数组的值，第三个数组它重复第二个数组的值。我该如何解决这个问题？

以下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，在功能和图像部分，它重复了第一个数据。

这是我的数组的var_dump：

Answer 1

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

Answer 2

你的代码简直就是一团糟。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)
    ];
}

将值从循环语句传递到数组，并且它具有重复值
