从数据库中获取逗号分隔值并存储在 PHP 中的数组中

Question

I'm trying to get fetch data from 'Seat' field in my database and get all values in an array. The seats field in my database looks like this so far:

Seats
A1, A2
A3

I want to turn these values into an array and print the array; but so far I've not had any luck

This is what I've tried so far:

$result = mysqli_query($conn, "SELECT Seats FROM flights_booked");

while($rows = mysqli_fetch_array($result)) {
 $seats=explode(',', $rows['Seats']);//what will do here
  print_r($seats);
  
}

My desired output is Array ( [0] => A1 [1] => A2 [2] => A3) when I print out the array - but so far I've got this:

Array ( [0] => A1 [1] => A2 ) Array ( [0] => A3 )

Is there any way in which I can get all values in the same array?

Try using array_merge , like that:

$seats = [];
$result = mysqli_query($conn, "SELECT Seats FROM flights_booked");
while($rows = mysqli_fetch_array($result)) {
  $seats = array_merge($seats, explode(',', $rows['Seats']));
}
print_r($seats);
