PHPMailer 给出错误消息："PHP Parse error: parse error, unexpected '{' in mailer.php on line 23"

Question

我为我的大学俱乐部做了一个网站，我用了PHPMailer。当我在自己的服务器中尝试它时，它运行良好。但是，在我将网站上传到学校的FTP后，我的PHPMailer无法正常工作。我联系了学校的IT，他们说："服务器上的PHP版本是4.3.9。您编写的代码必须适合它。在服务器的错误日志中，我们得到了以下错误：PHP 解析错误：解析错误，邮件中意外的"{".php在第 23 行"。我检查了我的代码十亿次，但我无法解决问题。这是我的代码：

<?
if(!empty($_POST['sender_mail'])
    || !empty($_POST['sender_name'])
    || !empty($_POST['sender_surname'])
    || !empty($_POST['sender_major'])
    || !empty($_POST['sender_schoolyear'])
    || !empty($_POST['sender_id']))
{
  phpinfo();
    require_once('class.phpmailer.php');
    include("class.smtp.php"); // optional, gets called from within class.phpmailer.php if not already loaded
    $smail = $_POST['sender_mail'];
    $name = $_POST['sender_name'];
    $surname = $_POST['sender_surname'];
    $major = $_POST['sender_major'];
    $schoolyear = $_POST['sender_schoolyear'];
    $id = $_POST['sender_id'];
    $mail = new PHPMailer(true); // the true param means it will throw exceptions on errors, which we need to catch
    $mail->IsSMTP(); // telli ng the class to use SMTP
    try { // Here is 23th line
      $mail->SMTPAuth   = true;                  // enable SMTP authentication
      $mail->SMTPSecure = "ssl";                 // sets the prefix to the servier
      $mail->Host       = "smtp.gmail.com";      // sets GMAIL as the SMTP server
      $mail->Port       = 465;                   // set the SMTP port for the GMAIL server
      $mail->Username   = "[e-mail]";  // GMAIL username
      $mail->Password   = "xxxxxxx";            // GMAIL password
      $mail->AddAddress('[e-mail]', 'Membership');
      $mail->SetFrom('[e-mail]', 'GGK');
      $mail->Subject = 'New Membership';
      $mail->IsHTML(true);
      $mail->Body = '<h3>New Membership</h3><br/><i><b>Name: </i></b><i>' . $name . '</i><br/><b><i>Surname: </i></b><i>' . $surname . '</i><br/><b><i>Mail: </i></b><i>' . $smail . '</i><br/><b><i>ID: </i></b><i>' . $id .  '</i><br/><b><i>Schoolyear: </b></i><i>' . $schoolyear . '</i><br/><b><i>Major: </b></i><i>' . $major . '</i>';
      $mail->Send();
      echo "Message Sent OK</p>n";
    } catch (phpmailerException $e) {
        echo -1;
      echo $e->errorMessage(); //Pretty error messages from PHPMailer
    } catch (Exception $e) {
      echo -1;  
      echo $e->getMessage(); //Boring error messages from anything else!
    }
}
else{
    echo -1;
}
?>

注意：我用ajax获取了表单的所有值，并将它们发布到mailer.php。

try/catch 仅在 PHP5 版本中提供。您需要执行其他错误捕获（if/else）才能进行测试。
