我有一個如下所示的 php 代碼，其中有一個 if 條件。php:if(mysqli_num_rows($result1) > 0){   // Line X    while($row = mysqli_fetch_array($result1)){        if($row['open'] == "true") {                if(!isset($_SESSION['admin'])) {                    $message = "user " . $row['user_name'] . " is currently editing the form. Want to take over ?";  // Line B                    echo "<script type='text/javascript'>if(confirm('$message')) {   } else {  };</script>";   // Line A                                            }            break;        }    }}我能夠在B 行集成$message。我想知道我應該在A 行進行哪些更改，以便可以將以下代碼集成到if(confirm('$message') 塊的花括號中：$username = $_SESSION['user_name'];$open="true";$write="1";$stmt=$connect->prepare("UPDATE trace_users SET write=0 WHERE write=1"); // revoke write access of all users$stmt=$connect->prepare("UPDATE trace_users SET open=?, write=? WHERE user_name=?");$stmt->bind_param('sss', $open, $write, $username);$stmt->execute();
