【中文标题】语法错误意外\'<\' [重复]【英文标题】：Syntax error unexpected '<' [duplicate]语法错误意外'<' [重复] 【发布时间】：2015-12-22 22:07:29 【问题描述】：对于结束标记所在的行，我不断收到此语法错误，我终生无法弄清楚我做错了什么。我以为我按照教科书的说明完成了这项作业，但如果我遇到错误，我显然没有。我一定是盲目的，因为我无法发现错误。任何帮助将不胜感激。

【问题讨论】：
突出显示出现此错误的行？ 对于初学者，第二个“ 发现错误的一个好方法是从代码中删除一些位，直到问题被隔离 - 您可以将噪音降低到可以清楚地看到问题的程度，或者删除的块可以解决问题，您可以孤立地看待它 - 如果您仍处于有大量代码块的阶段，那么您还没有这样做，我们当然不会为您这样做 @arch 没必要这么讨厌，即使是非常有经验的程序员也很难看到简单的语法错误，这就是为什么像任何专业程序员一样，重新审视某事通常会很快解决它知道 您在</body> 之前缺少 ?>，所以只需在</body> 之前添加 ?> 并检查。这是一个愚蠢的错误。
【参考方案1】：
你没有关闭最后一个 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";
?>
