Fixing the maximum PHP version

[s1lver]

We ran into problems when using AMQP queues. At the same time, tests for solving problems cannot be written anymore, since some packages have ceased to support PHP 5.6, including phpunit.
If you try to use a newer version of phpunit for PHP 8.0 or PHP 8.1, then you are faced with the fall of most tests for different drivers.

I spent some time and couldn't find a way to not have to rewrite all the tests and still be compatible with PHP 5.6 (#470)

In this regard, I have a suggestion to fix the maximum version of PHP 7.4 in README.md and suggest switching to queues from Yii3 if you need to work on PHP 8 or higher

Additional info

Q	A
Yii version	2.0.35

I don't think it will be easy to work with Yii3 queues within Yii2 but, honestly, I haven't tried. Maybe it's not as hard.

aw, didn't see that i'll try again of course

Something patches are not applied. I tried to return phpunit 4.8.36 the result is similar. I'm not sure I want to find out why fixes aren't being applied)

@samdark maybe I'm doing something wrong?

Would this mean that we can't reliably use yii2-queue with PHP 8.x or just the tests?

[samdark]

Just tests.

Not really. Some drivers do not work partially or completely, some have difficulties with support.
For example:

• there is no supported version of pecl for gearman, it is difficult to verify correct operation
• modern versions are not supported for beanstalk, currently there is a limit of 3 versions
• sqs is in an unclear state
• amqp contains errors, for example, heartbeat fixed in amqplib

I ran tests. The maximum working version of PHP is now 8.0. To support further, you must limit yourself to a minimum version of PHP 8.1

@s1lver @samdark what about pinning max version to 8.0/8.1 whichever is fully working and then open individual tickets for issues for higher versions so that only when all are fixed then we can raise that too?

What do you both think?
