What's going on when iis php can't load mysql?

Since a variety of technologies need to be used in the website development process, iis php and MySQL are also commonly used technologies. However, when using iis php, sometimes you encounter the problem that MySQL cannot be loaded. What should you do at this time?

First of all, we need to understand the basic concepts of iisphp and MySQL.

iisphp is a web server that allows users to run and manage web applications on Windows computers. MySQL is a relational database management system that is often used to store and manage data.

When iisphp cannot load MySQL, there may be several reasons:

1. The MySQL service is not started. Before using MySQL, you first need to start the MySQL service.
2. MySQL configuration error. When the MySQL configuration file is incorrect, iisphp will not be able to load MySQL normally.
3. PHP extension library is not enabled. iisphp needs to connect to MySQL through the PHP extension library. If it is not enabled, MySQL cannot be loaded normally.

The following introduces some methods to solve the problem that iisphp cannot load MySQL:

1. Check whether the MySQL service is started. In Windows systems, you can check the status of the MySQL service through the service manager. If the service is not started, you need to start the service manually.
2. Check MySQL configuration. The MySQL configuration file is usually located in the my.ini file in the MySQL installation directory. You can check whether the parameters in the configuration file are correct. It should be noted that the default port of MySQL is port 3306. If the MySQL port is occupied, it will also cause iisphp to be unable to load MySQL.
3. Enable PHP extension library. In the PHP configuration file php.ini, you need to uncomment the reference to the MySQL extension library to ensure that the extension library is enabled. If the extension library is not enabled, you can add the following configuration in php.ini:

extension=php_mysql.dll
extension=php_mysqli.dll

In the above code, php_mysql. dll is an extension library required when using MySQL, and php_mysqli.dll is an improved version for MySQL and can also be enabled at the same time.

Summary: When iisphp cannot load MySQL, you need to check the MySQL service status and check the parameters in the MySQL configuration file. You also need to check whether the PHP extension library is correctly enabled. The above method can effectively solve the problem that iisphp cannot load MySQL. I hope it can be helpful to everyone.
