As a continue for #6698
I reverted the changes related to .inc files.
If we want to support PHP8.4 we need to put the current default value for escape argument of str_getcsv function as without it the error is triggered

str_getcsv(): the $escape parameter must be provided as its default value will change

[samsonasik]

Please stop updating test files, that's there on purpose, and update str_getcsv needs test as it already default to \\.

[samsonasik]

Test is needed.

@samsonasik Why are you closing the PR?
If the test is needed wait for my extra push.

What are your plans for the support PHP8.4 if my PRs you don't want to consider?

[samsonasik]

because no test as I already suggest in your previous PR, and you keep updating test files, which unrelated.
