我收到此错误： 您的SQL语法有错误;检查与MySQL服务器版本对应的手册，以便在第1行的“WHERE user_id = 1”附近使用正确的语法
我已尝试过''或“”，甚至'。 “。和“'。''”。
我发现它没有任何问题。请帮忙！
它应该更新MySQL数据库，但它只输出该错误。

答案 0 :(得分：1)
您的问题出在此查询中：
$sql = "UPDATE `users`
SET `user_name` = '$new_name', `user_pass` = '$new_pass', `user_email` = '$new_email', `user_web` = '$new_web', `user_twitter` = '$new_twitter', `user_facebook` = '$new_facebook', `user_github` = '$new_github', `user_level` = '0', WHERE user_id = $mid";
特别是在最后一部分：
`user_level` = '0', WHERE user_id = $mid";
应删除where之前的最后一个逗号。
