Hey @mhzawadi
PHP 8.2 and 8.3 are on the roadmap for InvoicePlane V2.

The V1 of InvoicePlane was built with CodeIgniter and as long as they don't get ready for PHP 8.2, InvoicePlane can't either (if that makes sense)

V2 is in the works.

I am really confused about what to do with this information.

Since Debian-stable ships PHP8.2 I have no way to use something below this, what can I do to run IP?
If I got it right I can either use the information from #1009 (comment) to build IPv1 myself with an unofficial fork of CI3 (that supports PHP8.2) or try IPv2 which is still in development.

But this raises the next question, where can I find IPv2? Google gives me results of people talking about fit or at least 6 years, but I can not find any repository or download or any other signs of it's existence.

So, if I really need to run IP on PHP8.2 what is the best thing I can do?

If your looking for PHP not 8.2, this is made by a Deb dev and has PHP56 and up

So, if I really need to run IP on PHP8.2 what is the best thing I can do?

I am looking for the best option to run IP on PHP8.2.
But thanks for your answer anyway, it might be helpful for others.

I've answered the question about InvoicePlane V2 in this discussion

I am looking for the best option to run IP on PHP8.2.

IP & PHP 8.2:

(feel free to ask questions about below steps, if you like)

InvoicePlane was build with something that's called CodeIgniter version 3.

1. CodeIgniter 3 (after this: CI3) has 2 things:
   a. A branch with an almost working version for them for PHP 8.2,
   b. Someone who couldn't wait and just fixed it.

In your composer.json point to either of those 2 solutions, then run composer update

3. IP: Turn on any kind of debug you can find. error_reporting, everything. Now load IP on your PHP 8.2 with CI3 solution

4. You'll find a couple of similar cases: assignment of Dynamic Properties. Long story, but you'll find them in your error messages.

I don't know if that's all the errors you'll find, but it's the thing that changed between PHP 8.1 and 8.2

Once the dynamic properties situation has been resolved, the rest should be fairly easy to fix (famous last words)

Hope it helps
