MySQLi未找到错误

2021-12-25 00:00:00 php mysqli iis-5

我刚刚将我的网站部署到暂存环境，但出现以下错误:

I just deployed my website to a staging environment and am getting the following error:

Fatal error: Class 'mysqli' not found in D:ClientSitesaileyboiler.comwww
ewphpdb.php on line 11

起初我认为 MySQLI 没有安装，但运行 phpinfo() 会显示以下内容:

At first I assumed that MySQLI was simply not installed, but running a phpinfo() reveals the following:

对我来说，它看起来像是安装了 MySQLI(虽然我可能读错了).我该怎么办?

To me it looks like MySQLI is installed (though I could be reading this wrong). What should I do?

代码

class DB
{
    public static function GetConnection()
    {
        return new mysqli(DBHOST, DBUSER, DBPASSWORD, DEFAULTDATABASE);
    }
}

(第11行是return new mysql(...);)

更新

我将 extension=php_mysqli.dll 添加到位于 /Windows/php.ini 的 php.ini(根据 phpinfo()，这是正在加载的):

I added extension=php_mysqli.dll to my php.ini located at /Windows/php.ini (according to phpinfo(), this is the one being loaded):

Loaded Configuration File   C:WINDOWSphp.ini

但是错误仍然存​​在.我知道 mysqli.dll 存在于 C:phpext - 因为我可以看到该文件.现在怎么办?

But the error persists. I know that mysqli.dll exists at C:phpext - because I can see the file. What now?

推荐答案

我通过在 php.ini 中启用/编辑以下配置来纠正错误:

I got the error corrected by enabling/editing the following config in php.ini:

第一个(取消注释并添加配置):

1st (uncomment and add config):

include_path = "C:phpincludes"

第二(取消注释):

extension_dir = "ext"

第三(取消注释和编辑配置):

3rd (uncomment and edit config):

extension=D:/PHP/ext/php_mysql.dll
extension=D:/PHP/ext/php_mysqli.dll
