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?
Gereksinimler
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 is fully supported as of PHP 7.4.4. For older releases, the
mysql_xdevapi extension does
support it.

Supported authentication methods are listed in the "Loaded plugins" row of the "mysqlnd" section in phpinfo(). Look for plugins that start with "auth_plugin_…".
