Question

当我运行我的php脚本时，它无法正常工作。

出现“警告：无法修改标题信息-已发送标题”。我搜索了有关此问题的一些信息，但没有任何效果。这是我的代码：

<?php
    session_start();
?>
<?php
    $date = filter_var(trim($_POST['date']), FILTER_SANITIZE_STRING);
    $surename = filter_var(trim($_POST['surename']), FILTER_SANITIZE_STRING);
    $name = filter_var(trim($_POST['name']), FILTER_SANITIZE_STRING);
    $patronymic = filter_var(trim($_POST['patronymic']), FILTER_SANITIZE_STRING);
    $email = filter_var(trim($_POST['email']), FILTER_SANITIZE_STRING);
    $time = filter_var(trim($_POST['time']), FILTER_SANITIZE_STRING);
    $pass = filter_var(trim($_POST['pass']), FILTER_SANITIZE_STRING);
    $org = filter_var(trim($_POST['org']), FILTER_SANITIZE_STRING);

    print_r($date);


    if ($date == 0)
    {
        $_SESSION['error'] = "You haven't entered a date!";
        header('Location: /');
        exit();
    }

    if ($surename == 0)
    {
        $_SESSION['error'] = "You haven't entered a surename!";
        header('Location: /');
        exit();
    }

    if ($patronymic == 0)
    {
        $_SESSION['error'] = "You haven't entered a patronymic!";
        header('Location: /');
        exit();
    }

    if ($pass == 0)
    {
        $_SESSION['error'] = "You haven't entered a password!";
        header('Location: /');
        exit();
    }   

    if ($name == 0)
    {
        $_SESSION['error'] = "You haven't entered a name!";
        header('Location: /');
        exit();
    }   

        if ($time == "first")
            $half = 1;
    else
        $half = 2;

    $flag = false;

    require "bd_connection.php";

    $result = $mysql->query("SELECT * FROM `renters` WHERE (`data` = '$date' AND `half` = '$half')");
    $renters = $result->fetch_assoc();

    if (count($renters) == false) 
    {
        $mysql->query("INSERT INTO `renters` (`surename`, `name`, `patronymic`, `data`, `half`, `organization`, `pass`, `email`) VALUES ('$surename', '$name', '$patronymic', '$date', '$half', '$org', '$pass', '$email')");
        $flag = true;
    }
    else
    {
        $_SESSION['error'] = "This date and time have been already reserved!";
        header('Location: /');
        exit();
    }

    if ($flag == true)
    {
        $res = $mysql->query("SELECT * FROM `renters` WHERE (`data` = '$date' AND `half` = '$half')");
        $renter = $res->fetch_assoc();

        $string = $_FILES['file']['name'];
        $id = $renter['id'];
        if ($string == "")
        {
            $_SESSION['error'] = $string."You haven't attached file!";
            $mysql->query("DELETE FROM `renters` WHERE `id` = $id");
            header('Location: /');
            exit();
        }   
        else
        {
            $string = explode("." , $string, PHP_INT_MAX);
            $fileName = $id.".".$string[count($string)-1];
            move_uploaded_file($_FILES['file']['tmp_name'], "../docs/".$fileName);
            $_SESSION['success'] = "Successfully reseved for ".$date." !";
        }

        $mysql->query("UPDATE `renters` SET `doc` = '$fileName' WHERE `id` = '$id'");
    }

    $mysql->close();
    header('Location: /');
    exit();
?>

如您所见，我放了session_start（）;一开始另外，我正在使用没有BOM的UTF-8。
