php - 解析错误：语法错误，第 311 行 /home3/mafiasec/public_html/logincheck.php 中的意外 T_ELSE

Question

这是我的代码，这很烦人，因为我找不到问题。过去两天我一直在研究这个问题，但自己无法解决，我对编码比较陌生，所以请清楚地解释发生了什么因为我显然不会明白你在说什么。请帮我看看 - 这是代码。

    <?php

您已经else在第 298 行有一个声明。您不能在else此之后有另一个声明。

我认为这可能是因为您}在第 22 行的代码中缺少匹配项（该if()语句没有关闭}）。我猜你的else陈述应该匹配if()，在这种情况下，你需要在第 311 行}之前添加一个。else

此外，我同意其他人的观点，即您需要清理代码并使用适当的间距。它使调试更容易。

编辑：这是您的固定代码的相关部分：

</body>
<?php    } ?>
<?php   
      } else { 

         $sql = "UPDATE users SET nextlogin='".strtotime ("+20 seconds")."' WHERE username='".mysql_real_escape_string($username)."'";
         mysql_query($sql);

         $failtime = date('d-m-Y H:i:s', strtotime('+5 hours'));

         mysql_query("INSERT INTO loginfails SET id = '', ip = '$realip', time = '$failtime', username = '$username', password = '$password'");
         $sql = "INSERT INTO loginip SET id = '', ip = '$realip', time = '".strtotime ("+30 seconds")."'";
         $res = mysql_query($sql);

         echo"<b>Invalid Username/Password, Please go back and <a href=index.php>try again!</a></b>";


      }      // Here is the extra } you need to add


   } else {
      die("You did not attempt to login, <a href=index.php>Click</a> here to go to the login page!");
   }
?>

您提供的代码中没有“第 311 行”，但它非常丑陋。

我注意到在最后一个<?php ... ?>块中，您有一个没有相应的左大括号的右大括号 - 这很可能是错误的原因。然后你继续有一个else没有对应的if，紧接着是另一个else。两个elses? 那有什么意思？

我强烈建议从头开始重新编写此代码，注意正确组织和格式化它。这样，您将能够自己查找和修复此类错误。

没有 if 子句：我认为这是错误的原因。

$res = mysql_query($sql);

    echo"<b>Invalid Username/Password, Please go back and <a href=index.php>try again!</a></b>";

}else{
die("You did not attempt to login, <a href=index.php>Click</a> here to go to the login page!");
}
