我有一系列来自ebay api的已售产品。所以我想让（ value ）的总和searchResult->item->shippingInfo成立。我已经尝试过了，但是没有用
$value = array_sum(array_column($arr,'_value_'));
物品的实际价格。我给出了两个项目的示例，但是有100个项目。 foreach的一种方法，但是却变慢了

答案 0 :(得分：0)
您必须浏览阵列/响应，直到shippingServiceCost。
$eBayResponse = "(assume it's the eBay API JSON response decoded and valid)";
$sum = 0;
foreach ( $eBayResponse['findCompletedItemsResponse'] as $completedItemsResponse ) {
foreach ( $completedItemsResponse['searchResult'] as $searchResults ) {
foreach ( $searchResults['item'] as $items ) {
foreach ( $items['shippingInfo'] as $shippingInfos ) {
foreach ( $shippingInfos['shippingServiceCost'] as $shippingServiceCost ) {
if ( isset($shippingServiceCost['__value__']) ) {
$sum += $shippingServiceCost['__value__'];
}
}
}
}
}
}
echo $sum; // 99.97 with the corrected sample
