用这个替换你的 php 部分：<?phprequire('connection.php');$status = '';$text = '';$com = '';$url = 'index.php';function timer($url){    sleep(3);    header('Location: ' . $url); }if(isset($_POST['addCom'])) {    $com=  mysqli_real_escape_string($db,$_REQUEST['com']);    $text = mysqli_real_escape_string($db,$_REQUEST['text']);    $stmt = $db->prepare("insert into testcomments (com,text) values (?,?)");    $stmt->bind_param('ss',$com,$text);    $stmt->execute();    $status = "Done ";    $com= '';    timer($url);}?>
