@pmjones @harikt Could you review this PR?

[harikt]

Hey @kenjis ,

Thank you for the PR. As far as I know we were restricting the php version changes. So not sure this can be merged in that sense.

But my take is this can be merged for php has moved a lot to 8.x . And I don't know if there will be another 3.x for Aura framework.

I will leave the decision to pmjones.

I hope this PR will be merged.

But this is for PHP 7.x. So it should be merged into 4.x.
See auraphp/Aura.Cli_Kernel#12 (comment)
Can you create 4.x branch?

[harikt]

4.x is created. Let me know if you need anything else.

I've finished this PR. But Travis is gone and Scrutinizer raised error.

In my local environment, phpunit testing passed:

I can look into the test issues in this weekend. You can merge the branches in 4.x for now. pmjones has already approved the travis.com , but due to some reason the builds are not ready.

[kenjis]

phpunit 7 can't be installed on php8.

  Problem 1
    - phpunit/phpunit[7.0.0, ..., 7.5.20] require php ^7.1 -> your php version (8.0.8) does not satisfy that requirement.
    - Root composer.json requires phpunit/phpunit ~7 -> satisfiable by phpunit/phpunit[7.0.0, ..., 7.5.20].

I will update to phpunit 8.x. Because phpunit 8 requires php 7.2 or later and supports php8.
phpunit 9 requires php 7.3 or later.

[harikt]

I have updated the github workflow. You can try again.

[harikt]

@kenjis if this works you can make the necessary changes to all other repos also.

[harikt]

FYI : I have created #18 for testing. You can see the phpunit it complains is due to wrong code. So all seems well.

[harikt]

You can see the build. update the .github/actions/php.yml with the php version you need.

@harikt Thanks!

#15 (comment)
I will send another PR for it.

[harikt]

Please refer composer.json and .github/workflows/php.yml for other repos you want the ci. I am moving on.
