示例代码：

foreach ($data as &$attr) {
    foreach ($attr as &$p) {
        $pd = $repository->get($p['sku'], false, $storeId);
        $p['price'] = $pd->getPrice();
        $p['image'] = $imageHelper
            ->init($pd, 'product_thumbnail_image')
            ->resize($this->imageH, $this->imageW)
            ->getUrl();
        $stockQty = $this->productService->getCurrentWebsiteStockSaleableQty($pd);
        $p['stock'] = $stockQty;
        $p['website'] = $website_id;
        $p['website_name'] = $pd->getStore()->getWebsite()->getName();
    }
}

&$attr后再在第二层循环&$p

它将不释放地址指针，而是在数组最后一个直接带上&array(，以下是问题返回数据

数据响应查看

}

<pre>

引发最后一个带上地址指针

 [5]=>

  &array(12)

&array

解决：

方式一、将内循环的&$p的地址引用去掉

方式二、修改代码为

foreach ($data as &$attr) {
    foreach ($attr as $key=>$p) {
        $pd = $repository->get($p['sku'], false, $storeId);
        $p['price'] = $pd->getPrice();
        $p['image'] = $imageHelper
            ->init($pd, 'product_thumbnail_image')
            ->resize($this->imageH, $this->imageW)
            ->getUrl();
        $stockQty = $this->productService->getCurrentWebsiteStockSaleableQty($pd);
        $p['stock'] = $stockQty;
        $p['website'] = $website_id;
        $p['website_name'] = $pd->getStore()->getWebsite()->getName();
        $attr[$key] = $p;
    }
}
