找不到mysqli类 [英] Class mysqli not found

问题描述

我已使用mysqli连接到我的应用程序中的数据库.它工作了好几天，然后突然开始显示以下错误:

I have used mysqli to connect to the database in my application. It worked fine for a few days and suddenly it started showing the following error:

致命错误:找不到类'mysqli'

Fatal error: Class 'mysqli' not found

我用来连接数据库的行是:

The line I used to connect to the database is:

 $link = new mysqli('localhost', 'uname', 'password', 'scripts');

能否请您告诉我可能出了什么问题?

推荐答案

好，您需要拥有

Well you need to have MySQLi installed before you can use it. Also you'll have to enable it (when installed) in your php.ini file.

您可以使用以下代码测试是否具有该代码:

You can test if you have it with this code:

if (!function_exists('mysqli_init') && !extension_loaded('mysqli')) {
    echo 'no mysqli :(';
} else {
    echo 'we gots it';
}

完成此操作后，仍然出现错误，请向我们提供更多详细信息(操作系统，PHP版本等)

When you've done that, and there still is an error, please provide us with more details (OS, PHP version etc)
