Answer 1

PHP 8.1 no longer supports passing null values ​​to trim, prior to 8.1 these values ​​were internally converted to empty strings, in 8.1 they will no longer be Change.

If you have access to the code, you should check if the value is empty before putting it in trim, or default the value to an empty string. You need to manually fix those areas in the error output.
