如何使用while语句中的函数来获取关联数组值?

I'm trying to figure out how to get value from associative array by putting a function inside a while statement?

  while($row = $result->fetch_assoc()) {
  $message = $row["message"];
  $reply = $row["reply"];

   $object->gets("'.$message.'", function ($obj) {
                $obj->posts("'.$reply.'");
            });

  } 

Obviously that code wont work because the variable $reply needs to be initialized inside the function to work. How can I do this procedural style? Or is there a better way to do this?

    I'm assuming you want to be able to access the $reply value inside your function?

    In order to get the variable within the scope of the function do following :

    while($row = $result->fetch_assoc()) {
      $message = $row["message"];
      $reply = $row["reply"];
    
       $object->gets("'.$message.'", function ($obj) use ($reply) {
                    $obj->posts("'.$reply.'");
                });
    
      }
