$manufacturer references to an array. Try:
$manufacturer 对数组的引用。尝试：
echo $manufacturer['name'];
or
或者
echo $manufacturer['manufacturer_id];
As you can see on your var_dump, your variable $products[$product['product_id']]['manufacturers']is an array composed by three other arrays. So each iteration of your loop will assign an array to $manufacturer variable.
正如您在 上看到的var_dump，您的变量$products[$product['product_id']]['manufacturers']是一个由其他三个数组组成的数组。因此，循环的每次迭代都会为 $manufacturer 变量分配一个数组。
