CI4 mbstring deprecated

What functions have been deprecated?

mbereg() and mberegi(): Replaced by mb_ereg() and mb_eregi() in PHP 7.0
mbsplit(): Replaced by mb_split()

QPrint, Base64, Uuencode, and HTML-ENTITIES: Deprecated for all MBString functions
mbstring.http_input, mbstring.http_output, mbstring.internal_encoding: Deprecated in favor of default_charset

How to fix deprecated function errors?

Suppress the warnings by adding a line to the php.ini file.
Upgrade your PHP to a higher version.

The helpdesk of the hosting where I uploaded the application sent me: https://www.php.net/manual/it/mbstring.c...ration.php

I am using version 8.x (2 >) of PHP.

If you tell me that there is nothing to worry about and that it is enough to just suppress the error messages, I will adapt.

Thanks.
