Question

productid    Qty    SupplierId 
M0001        -      S0001
M0002        -      S0002
M0001        -      S0001
M0002        -      S0002

Quantity is an input. manually given by user


$data = json_decode(file_get_contents("php://input"));
$Product=$data->Product;
$quantity=$data->quantity;
$suppliername=$data->suppliername;

sort($suppliername); //S0001,S0001,S0002,S0002

            foreach($suppliername as $index => $value)
            {   
                $ProductArr = $Product[$index];
                $QtyhArr = $quantity[$index];
                $SupplierArr = $suppliername[$index];

                $qry_resArr = $conn->prepare("INSERT INTO Table(Supplier,Product,Qty) VALUES (?,?,?)"); 
                $qry_resArr->execute(array($SupplierArr,$ProductArr,$QtyhArr));
            }

如何在foreach循环之前基于排序数组过滤数组值。我需要根据排序的数组传递product，qty值。这该怎么做？。谢谢你

Expected result: I need to pass into query below format
S0001,M0001,300
S0001,M0001,70
S0002,M0002,150
S0002,M0002,100

Answer 1

在排序时不应更改值的索引，因此您应使用asort而不是sort()

所以它会像

asort($suppliername);

foreach($suppliername as $index => $value){
    $ProductArr  = $Product[$index];
    $QtyhArr     = $quantity[$index];
    $SupplierArr = $suppliername[$index];
}

它根据需要提供输出
