如何在数组中获取值并在while循环中提取下面写一些行代码，请帮助

$sql = "SELECT * FROM Table WHERE id=1";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
$view = $result->fetch_assoc() 
$arrrrrrr = $view['quiz_que'];
    $arraysss = [$arrrrrrr];                
    print_r($arraysss);

Ourput数组（[0] => A1，F2,3,4，S5,6,7,816,17）

我想要什么

$a = [1, 2, 3, 4];
print_r($a);

输出数组（[0] => 1 [1] => 2 [2] => 3 [3] => 4）

Answer 1

尝试一下

$arrrrrrr = $view['quiz_que'];//A1,F2,3,4,S5,6,7,816,17
$quiz_queArray = explode(',',$arrrrrrr);
echo'<pre>';print_r($quiz_queArray);die;

输出：

Array
(
    [0] => A1
    [1] => F2
    [2] => 3
    [3] => 4
    [4] => S5
    [5] => 6
    [6] => 7
    [7] => 816
    [8] => 17
)
