MySQL 8 is the latest version of the popular open-source database management system, and it introduces many new features and improvements over previous versions. However, some PHP 5.6 applications may not be compatible with MySQL 8, which can cause errors and issues when trying to use the two together.
To make MySQL 8 work with PHP 5.6 apps, you will need to make some changes to your PHP code. One of the most important changes is to update the PHP MySQL extension to the latest version. MySQL 8 uses a new authentication method that is not supported by the older PHP MySQL extension, so you will need to update it to a version that supports the new authentication method.
Another important change is to update your MySQL connections to use the new default password plugin in MySQL 8. In previous versions of MySQL, the default password plugin was “mysql_native_password”, but in MySQL 8, it has been changed to “caching_sha2_password”. To make your PHP 5.6 app work with MySQL 8, you will need to update your MySQL connections to use the new default password plugin.
In addition to these changes, you may also need to make some other updates to your PHP code to ensure compatibility with MySQL 8. This can include updating your SQL queries to use the new features and syntax introduced in MySQL 8, and making sure that your code is using the latest version of the MySQLi extension.
Overall, making MySQL 8 work with PHP 5.6 apps requires some careful planning and code updates, but the effort is worth it to take advantage of the new features and improvements in MySQL 8. By following the steps outlined above, you can ensure that your PHP 5.6 apps are compatible with MySQL 8 and can continue to run smoothly and efficiently.
