Hi @Piedlow, Bert
PHP 8.4 still doesn't have an MSSQL driver.
If you have feedback, the best way to contact the Microsoft Drivers for PHP for SQL Server team is by filing an issue on the GitHub repository.
And as Erland answered, it is not suggested to perform this in production before the new version released. Cause there has been some issues discussed on this thread.
Best regards,
Cosmog
