这是响应即时通讯我希望获得键的基础中的值使用每个4个对象的循环我尝试了许多解决方案发布在这里，但没有人工作..

需要帮助请回复！提前谢谢

Answer 1

$productsTitles = array();
foreach ($result->result->products as $product) {
    $productsTitles[] = $product->productTitle;
}
var_dump($productsTitles);

Answer 2

基本上你在这里有一个很好的混合数组和对象。你的2个元素的外部数组包含你关心的“结果”和“errorCode”。

首先你需要遍历你拥有的每个结果，然后你需要找到所需的字段（根据评论“imageURL”）并将其保存在某个地方（或者回显它，无关紧要）。

我假设你的对象数组被称为$result

$imageUrls = [];
if (isset($result["results"]) && isset($result["results"]->products) {
    foreach ($result["results"]->products as $productObject) {
         $imageUrls[] = $productObject->imageUrl;
    }
}

print_r($imageUrls); // This just dumps the output, you can do whatever else you want with it.

PHP：使用循环从多个stdclass对象的数组中提取值
