blocks|key|5896918|text|我在一段时间前也遇到了这个错误，我花了很长时间才找到解决这个问题的方法。基本上你需要做的就是给你的php环境添加一个扩展。以下解决方案适用于运行Apache和MySQL的Microsoft+Windows+Server+2003：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5896919|5896920|找出你的php文件夹在运行moodle的服务器上的位置。通常位于c：\php.|unordered-list-item|5896921|打开php.ini。在该文件中，您将找到;extension=php_mysqli.dll。删除分号。|5896922|保存文件。|5896923|重新启动Apache并转到Moodle网站。|5896924|5896925|开始吧，从现在开始你应该会很好;)希望这对你有帮助！！|5896926|entityMap^0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|R|8|@]|9|@]|A|$]]|$1|C|3|D|5|E|7|S|8|@]|9|@]|A|$]]|$1|F|3|G|5|E|7|T|8|@]|9|@]|A|$]]|$1|H|3|I|5|E|7|U|8|@]|9|@]|A|$]]|$1|J|3|K|5|E|7|V|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|W|8|@]|9|@]|A|$]]|$1|M|3|N|5|6|7|X|8|@]|9|@]|A|$]]|$1|O|3|-4|5|6|7|Y|8|@]|9|@]|A|$]]]|P|$]]

I got this error as well some time ago and it took me quite a while to figure out a way how to solve that. Basically all you need to do is add an extension to your php envoirment. The following solution fits to a Microsoft Windows Server 2003 running Apache and MySQL:

<ul>
<li>Find out where your php folder is located on the server that moodle is running on. It is usually at c:\php.</li>
<li>Open php.ini. Within the file you will find ;extension=php_mysqli.dll. Delete the semicolon. </li>
<li>Save the file.</li>
<li>Restart Apache and go to your Moodle website.</li>
</ul>

Here we go, you shold be fine from now on ;) hope this helped!!

For those looking for an answer for LINUX

uncomment

;extension=mysqli.so

in 'Dynamic Extensions' section in file 'php.ini' located in php folder ('/etc/php/php.ini' in my case)

blocks|key|5896988|text|您需要安装以下php-mysql包，然后重新启动Apache+web服务器。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|5896989|entityMap^0|7|9|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

You need to install the following package <code>php-mysql</code> and then restart the Apache web server.

blocks|key|338271|text|你需要安装下面的php-mysql包，然后重启Apache+web+server.This就解决了我的问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|338272|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

You need to install the following package php-mysql and then restart the Apache web server.This is resolved my issue.

blocks|key|4168291|text|我也有同样的问题。在php.ini中通过删除以下行中的';‘启用mysqli扩展后：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4168292|;extension=mysqli|code-block|syntax|javascript|4168293|到目前为止，一切都没有改变。然后我在网上看到一个帖子，说你必须安装php-mysqlnd包。使用以下命令安装后，问题已解决：|4168294|sudo+apt+install+php-mysqlnd|4168295|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

I have the same problem. After enabling mysqli extension in php.ini by removing the ';' from the following line:

<pre><code>;extension=mysqli
</code></pre>

Nothing changed up to now. Then I saw a post on the net that said you have to install php-mysqlnd package. After installing it using following command the problem resolved:

<pre><code>sudo apt install php-mysqlnd
</code></pre>

blocks|key|3688015|text|我正在使用Xammp并运行多个版本的PHP，我发现我需要更新我的php.ini文件以指向正确的扩展目录。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3688016|找到关键的一行：|3688017|;+extension_dir+=+"./"

I am Using Xammp and runing multiple PHP versions, I found I needed to update my <code>php.ini</code> file to point to the correct extension directory.
Find the key line:
<pre><code>; extension_dir = &quot;./&quot;
; On windows:
extension_dir = &quot;C:\xampp\php-5460\ext&quot; ;&lt;--- make sure this is correct

</code></pre>

I am running Moodle test environment on Window Vista having PHP 5.2.10 and MySQL 5.1.36-Community. When I upgrade from Moodle 1.9.9 to 2.0, I am getting the following error. 

<pre><code>Error: database driver problem detected

The site administrator should verify server configuration

PHP has not been properly configured with the MySQLi extension so that it can communicate with MySQL. Please check your php.ini file or recompile PHP. MySQLi extension is not available for PHP 4.
</code></pre>

I also tried to change the dbtype='mysqli' in config.ini and still see same error.

I would really appreciate if you can provide some suggestion to resolve this error.

Thank you in advance.
