我想在我的网站上制作搜索帐户系统
我搜索：savadeekab
我的数据库：
DisplayName Email Password SecurityQuestion SecurityAnswer Rank
savadeekab [email protected] 123456 yearMotherBorn 1978 admin
savadeekab [email protected] 5555 yearGrandFatherBorn 1923 member
test [email protected] test yearFatherBorn 1977 member
搜索“savadeekab”后我想要的结果
DisplayName Email Password SecurityQuestion SecurityAnswer Rank
savadeekab [email protected] 123456 yearMotherBorn 1978 admin
savadeekab [email protected] 5555 yearGrandFatherBorn 1923 member
但是当我搜索“savadeekab”时出现这个错误：
致命错误：Uncaught mysqli_sql_exception: Too many keys specified; D:\NewXAMPP\htdocs\Main\Account\Admin llUserSearch.php:22 中允许最多 64 个键
堆栈跟踪：

#1 {main} 在第 22 行的 D:\NewXAMPP\htdocs\Main\Account\Admin llUserSearch.php 中抛出
我的PHP代码：

我已经尝试在互联网上搜索它说我需要使用这个命令并编译它
./configure --prefix=/usr/local/mysql --with-max-indexes=255但是我不知道在哪里编译它 PS：我的主机是本地主机（phpmyadmin）
我发现很多帖子都问过这个问题，但我没有得到任何适合我的答案。谢谢你回答我
问题！
