未捕获的错误:连接到数据库时调用未定义的函数mysqli_connect() [英] Uncaught Error: Call to undefined function mysqli_connect() when connecting to the database

问题描述

在PHP 7.0和PHP 7.1上尝试使用mysqli连接到数据库时出现错误

I get an error when trying to connect to my database with mysqli on PHP 7.0 and PHP 7.1

PHP致命错误:未捕获错误:调用/home/mywebsite/public_html/connection.php:7中未定义的函数mysqli_connect()

PHP Fatal error: Uncaught Error: Call to undefined function mysqli_connect() in /home/mywebsite/public_html/connection.php:7

$conn = mysqli_connect($DBhost,$DBuser,$DBpass,$DBname);

推荐答案

1. 首先检查是否启用了mysqli:phpinfo()

您的服务器上未安装mysqli PHP扩展.与您的服务器管理员联系.

The mysqli PHP extension is not installed on your server. Contact to your server administrator.

OR

1. 如果您自己托管服务器，则在 php.ini 文件中，删除扩展名 extension = php_mysqli.dll 前面的分号.

1. If you host the server yourself, in the php.ini file remove the semicolon in front of the extension extension=php_mysqli.dll.
