Question

$products = Array ( [products] => Array ( [0] => 12,11,10 [1] => 16,15,14 
[2] => 600,103,20 ) );
$info = implode(",",$_POST['product']);
$info1 = implode(",",$_POST['product_weight']);
$info2 = implode(",",$_POST['quantity']);

admin_orderrequest_add($params,$products,$obj);

foreach($products as $k=>$v)
{
  echo $product_id = $v[0];
  echo $product_weight_id = $v[1];
  echo $product_quantity = $v[2];
  $weight_info = admin_get_weight_info($product_weight_id,$obj);
}

现在第一次输出：
12,10,11
16,15,14
600,103,20

必需的输出： 第一次
12
16
600

第二次数组的所有第二个值
第三次数组的所有第三值

Answer 1

array_column()用于通过同一键生成新数组。因此，您可以使用\n

array_column()

Answer 2

MH2K9发布的答案有效，如果要遍历它们，也可以使用以下代码

$products = [[12,11,10], [16,15,14], [600,103,20]];

if(!empty($products) && isset($products[0])){
    $product_ids = $products[0];
    $product_weight_ids = $products[1];
    $product_quantities = $products[2];

    foreach($product_ids as $key=>$v)
    {
        echo $product_id = $v; echo "<br/>";
        echo $product_weight_id = $product_weight_ids[$key];echo "<br/>";
        echo $product_quantity = $product_quantities[$key];echo "<br/>";
        echo "<br/>";echo "<br/>";echo "<br/>";
        $weight_info = admin_get_weight_info($product_weight_id,$obj);
    }
}

输出：

12   16   600

11   15   103

10   14   20

foreach循环打印逗号分隔的字符串数组
