PHP 8.2.0 Beta 3 available for testing

Requirements

In order to have these functions available, you must compile PHP with support for the mysqli extension.

MySQL 8

When running a PHP version before 7.1.16, or PHP 7.2 before 7.2.4, set MySQL 8 Server's default password plugin to mysql_native_password or else you will see errors similar to The server requested authentication method unknown to the client [caching_sha2_password] even when caching_sha2_password is not used.

This is because MySQL 8 defaults to caching_sha2_password, a plugin that is not recognized by the older PHP (mysqlnd) releases. Instead, change it by setting default_authentication_plugin=mysql_native_password in my.cnf. The caching_sha2_password plugin will be supported in a future PHP release. In the meantime, the mysql_xdevapi extension does support it.

PHP 7.4 now supports MySQL with caching_sha2_password, although it is a bit unclear around older versions, there seems to be conflicting reports. What is the support of caching_sha2_password in PHP < 7.4?
