我如何爆炸[group_concat(DISTINCT LineItem.ItemID)] => 600278,WH1502。

我尝试了这个，但没有显示任何内容

$result = mysqli_query($con,"SELECT ...")

while($row = mysqli_fetch_array($result)) { 
$r = $row[LineItem.ItemID];
 explode(',',$r);
}

也试过

$result = mysqli_query($con,"SELECT ...")

while($row = mysqli_fetch_array($result)) {
   $r = $row[group_concat(DISTINCT LineItem.ItemID)];
   explode(',',$r);
 }

// ARRAY

  Array ( 
        [0] => XXOR001# 
        [CustomerID] => XXOR001# 
        [1] => XXXX INDUSTRIES 
        [Customer_Bill_Name] => XXX INDUSTRIES 
        [2] => WILL CALL [WhichShipVia] => WILL CALL [3] =>

        [Quantity] => 30.0000000000000000000 
        [11] => 600278,WH1502 
        [group_concat(DISTINCT LineItem.ItemID)] => 600278,WH1502

我不确定您要做什么，但您可以尝试使用此类内容来帮助您提供代码的可见性：

while($row = mysqli_fetch_array($result)) { 
    $r = $row[LineItem.ItemID];
    $lineItemArray = explode(',',$r);
    print_r($lineItemArray);
}

explode()根据指定的分隔符从字符串创建数组。考虑这个例子：

$r = '600278,WH1502';
$rarray = explode(',',$r);
print_r($rarray);

//Output:
Array
(
    [0] => 600278
    [1] => WH1502
)
