PHP 8.0 was released recently at the time of this post is written.
Surprisingly, Codeigniter 3 does not generate any error message this far in PHP 8.0.
Meanwhile, Codeigniter 4 generates some user warning in PHP 8.0 (update on August 2021 : there is no warning anymore in my scripts).
Fortunately my projects are still in Codeigniter 3, so i can use them with PHP 8.0.
Update :
- There is bug in session flashdata : the data won’t be deleted after retrieved.
Error in codeigniter3 in php v8.0 cart library and flashdata.
@Krishan : You are correct, session flashdata won’t be deleted after retrieved.
Regarding cart library, i do not use it so i have not tested it.
Thanks.
A pull request has been made (and accepted) in the GitHub repo which fixes the flashdata issue. Until a new version of CI3 is released you can look up the fix manually
@Gareth : thank you for the answer.
