使用以上代码，一切都已设置，但 关于checkcredts.php 分析错误：语法错误，第33行的C:\xampp\htdocs\cnr\Connection.php中出现意外的“$\u Connection”T\u变量，请尝试：

替换

并添加；在$\u UsersTable=playerdata之后，只需添加；在$\u UsersTable=playerdata$\u UsersTable=playerdata之后，这里缺少一个分号，请在发布代码时删除与问题不直接相关的任何内容。那份版权声明只会让人分心。看到C 2012，代码大概在四年多的时间里没有打补丁，这并不令人鼓舞。警告：如果你只是在学习PHP，请不要学习过时的接口。这很糟糕，已经在PHP7中删除了。替换类和指南类有助于解释最佳实践。请确保您的用户参数是正确的，否则将导致严重的错误。您看到的是一个语法错误…不是mysql\u connect错误..对不起，我正在学习php:除非您有很好的理由，否则不要使用错误抑制@operator。此外，单引号字符串不会插值。第三，不要将用户名、主机和密码等敏感信息放在用户看到的错误消息中。这就是死亡的作用。

$_Connection = mysql_connect($_Host, $_User, $_Pass) or die('Could not connect to $_Host with $_User using password $_Pass');

@mysql_connect($_Host, $_User, $_Pass) or die('Could not connect to $_Host with $_User using password $_Pass');
