and here the var_dump of my variable

这里是我的变量的var_dump

array(3) {
      [0]=>
      array(2) {
        ["name"]=>
        string(5) "Apple"
        ["manufacturer_id"]=>
        string(1) "8"
      }
      [1]=>
      array(2) {
        ["name"]=>
        string(3) "HTC"
        ["manufacturer_id"]=>
        string(1) "5"
      }
      [2]=>
      array(2) {
        ["name"]=>
        string(4) "Sony"
        ["manufacturer_id"]=>
        string(2) "10"
      }
    }

$manufacturer references to an array. Try:

$ manufacturer引用数组。尝试:

echo $manufacturer['name'];

or

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var_dump上看到的,您的变量$ products [$ product ['product_id']] ['manufacturers']是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。
