Question

我一直收到关闭标签所在行的语法错误，而且我不能在我的生活中弄清楚我做错了什么。我以为我按照教科书的说明进行了这项任务，但如果我收到错误，我显然没有。我必须失明，因为我无法发现错误。任何帮助将不胜感激。

您没有关闭最后一个else块

else {
    $SenderAddress= "$Sender <$Email>";
    $Headers= "From: $SenderAddress\nCC:
    $SenderAddress\n";
    // Substitute your own email address for // recipient@example.com
    $result = mail ("recipient@example.com",
    $Subject, $Message, $Headers);
    if ($result)
    echo "<p>Your message has been sent. Thank you, " . $Sender . ".</p>\n";
    else
    echo "<p>There was an error sending your message, " .
    $Sender . ".</p>\n";
} ?>
