如何在PHP 7中启用MySQLi扩展? [英] How can I enable the MySQLi extension in PHP 7?

问题描述

我已经在Ubuntu 14.04(Trusty Tahr)上安装了PHP 7和MySQL 5.5.47.

I have installed PHP 7 and MySQL 5.5.47 on Ubuntu 14.04 (Trusty Tahr).

我已使用以下方法检查了已安装的扩展程序:

I have checked installed extension using:

sudo apt-cache search php7-*

它输出:

我也无法使用phpinfo()看到MySQLi扩展.如何在PHP 7中启用/安装MySQLi扩展?

I am not able to see the MySQLi extension using phpinfo() either. How can I enable/install MySQLi extension in PHP 7?

这就是为什么我不能使用phpMyAdmin的原因.它说:缺少mysqli扩展名."

That's why I cannot use phpMyAdmin. It says "The mysqli extension is missing."

推荐答案

我找到了解决方案.我可以在php.ini中启用MySQLi扩展.我只是在php.ini中取消注释了这一行:

I got the solution. I am able to enable MySQLi extension in php.ini. I just uncommented this line in php.ini:

extension=php_mysqli.dll

现在，MySQLi运行良好.这是Apache 2，PHP 7和Ubuntu 14.04环境中的php.ini文件路径:

Now MySQLi is working well. Here is the php.ini file path in an Apache 2, PHP 7, and Ubuntu 14.04 environment:

/etc/php/7.0/apache2/php.ini

默认情况下，PHPi 7中禁用了MySQLi扩展.

By default, the MySQLi extension is disabled in PHP 7.
