If you are on Linux, you shouldn't have DLL files but SO files. So first, you have to remove / disable the php_mysqli.dll you added in php.ini.

如果你在 Linux 上，你不应该有 DLL 文件，而是 SO 文件。因此，首先，您必须删除/禁用您在 php.ini 中添加的 php_mysqli.dll。

In order to use mysqli, you should then :

为了使用 mysqli，你应该：

• install the package for Ubuntu : apt-get install php-mysql
• check if it is already enabled (with phpinfo()for example)
• if not enabled, enable the module - check in /etc/php/mods-available/folder if there is a mysqli.ini, containing extension=mysqli.so, then check for CLI / FPM / Apache / other if there is the symbolic link pointing to this file (for example for CLI, in /etc/php/cli/conf.d/: 20-mysqli.ini -> ../../mods-available/mysqli.ini)
• restart php / apache / nginx depending what you are using

• 为 Ubuntu 安装软件包： apt-get install php-mysql
• 检查它是否已经启用（phpinfo()例如）
• 如果未启用，启用模块-在检查/etc/php/mods-available/文件夹，如果有一个mysqli.ini，包含extension=mysqli.so，然后检查CLI / FPM / Apache的/其他如果存在符号链接指向该文件（例如，用于CLI，在/etc/php/cli/conf.d/：20-mysqli.ini -> ../../mods-available/mysqli.ini）
• 根据您使用的内容重新启动 php / apache / nginx

In my case it happened because i uncommented the extension=php_mysqli.dllline in php.ini file for running some other package. After googling around i found that you should not uncomment anything directly from php.ini instead you should install the required php extension and it will do the rest.

就我而言，这是因为我取消了extension=php_mysqli.dllphp.ini 文件中运行其他包的行的注释。在谷歌搜索之后，我发现你不应该直接从 php.ini 取消注释任何东西，而是应该安装所需的 php 扩展，它会完成剩下的工作。

运行Phpinfo()搜索您的php.ini路径

I just had the same problem and realised they were two folders in my /etc/php/7.0, which were apache2and cli. Turned out the extension line in cli/php.iniwas uncommented with the dll file, not the one in apache2directory. Commenting it just solved the problem.

我刚刚遇到了同样的问题，并意识到它们是我的两个文件夹/etc/php/7.0，分别是apache2和cli. cli/php.ini结果是 dll 文件中的扩展行没有注释，而不是apache2目录中的。评论它只是解决了问题。

I have recently encountered this problem on ubuntu16.04, I finally resolve it by adding a semi-colon at each line like extension=php_*.dll,I think that is because LAMP on ubuntu is intelligent enough，it automatically opens all of the extensions for us. And on windows,we have to enable the extensions manually by remove the semi-colon at each line like ;extension=php_*.dllin php.ini.

我最近在ubuntu16.04上遇到了这个问题，最后我在每行加一个分号解决了extension=php_*.dll，我认为是因为ubuntu上的LAMP足够智能，它会自动为我们打开所有扩展。而在Windows上，我们必须通过手动删除启用扩展在像每行的分号;extension=php_*.dll在php.ini。

I managed to solved it like this:

我设法解决了这个问题：

1. add libs to php.ini (etc/php/7.3/apache2; etc/php/7.3/cli folders) extension=pdo_mysql.so

2. restart apache (sudo systemctl restart apache2)

3. comment libs in php.ini (etc/php/7.3/apache2; etc/php/7.3/cli folder) extension=pdo_mysql.so

4. go etc/php/7.3/mod_available

5. comment extension (because it is already loaded), for example, etc/php/7.3/mod_available/pdo_mysql.ini ;extension=pdo_mysql.so

1. 将库添加到 php.ini (etc/php/7.3/apache2; etc/php/7.3/cli 文件夹) extension=pdo_mysql.so

2. 重启 apache (sudo systemctl restart apache2)

3. php.ini 中的注释库（etc/php/7.3/apache2; etc/php/7.3/cli 文件夹） extension=pdo_mysql.so

4. 去 etc/php/7.3/mod_available

5. 注释扩展（因为已经加载了），例如 etc/php/7.3/mod_available/pdo_mysql.ini ;extension=pdo_mysql.so

If you see mcrypt.so under /etc/php/7.2 or /etc/php/7.3 just delete it and restart the server it will resolve the issue. As when we updrage the php to latest version that file may get stored to latest versions which is not required.

如果您在 /etc/php/7.2 或 /etc/php/7.3 下看到 mcrypt.so 只需将其删除并重新启动服务器即可解决问题。当我们将 php 升级到最新版本时，该文件可能会存储到不需要的最新版本。

I used following commands:

我使用了以下命令：

cd /etc/php/7.3

sudo rm -rf mcrypt.so

sudo service apache2 restart

cd /etc/php/7.3

须藤 rm -rf mcrypt.so

须藤服务 apache2 重启

Just comment out all lines with .dll extensions because you are on Ubuntu. Ubuntu support .so files.

只需注释掉所有带有 .dll 扩展名的行，因为您使用的是 Ubuntu。Ubuntu 支持 .so 文件。

In php.iniunder Dynamic Extensionsthe line extension=php_mysqli.dllwas enabled.

在php.ini根据Dynamic Extensions该行extension=php_mysqli.dll已启用。

I disabled it by adding a semi-colon at the head of the line ;extension=php_mysqli.dll.

我通过在行的开头添加一个分号来禁用它;extension=php_mysqli.dll。

Saved and exited php.ini. Restarted Apache.

保存并退出php.ini。重新启动Apache。

This resolved the error for me.

这为我解决了错误。
