PHP8.1 support

[Jeckerson]

Feature Request

Current fatal error that I get with latest version of box:

Fatal error: During inheritance of IteratorAggregate: Uncaught ErrorException: Return type of _HumbugBox113887eee2b6\Symfony\Component\Console\Helper\HelperSet::getIterator() should either be compatible with IteratorAggregate::getIterator(): Traversable, or the #[ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in phar:///srv/box.phar/vendor/symfony/console/Helper/HelperSet.php:44

Make support for PHP8.1 possible.

This requires more work to be done on PHP-Scoper side first.

[Jeckerson]

According Symfony they already support PHP 8.1.

[Jeckerson]

Also, this feature really blocks generation of .phar which then can be used inside Phalcon tests.

[theofidry]

According Symfony they already support PHP 8.1.

The problem is not Symfony on which the app is built but PHP-Scoper which is used to bundle the PHAR.

Thinking about this again, since Box does not use any PHP 8.0 or 8.1 features, maybe it won't require more than "just" updating the dependencies.

[Jeckerson]

So you suggest to compile .phar with PHP7.4 and it might work with PHP >= 8.0 ?

[theofidry]

No I meant to build box on PHP 8.1

[Jeckerson]

@theofidry Do you need any help with this?

@theofidry has right when he said that PHP 8.1 compatibility is broken by humbug/php-scoper (https://github.com/box-project/box/blob/3.14.0/composer.json#L51) that did not support a compatible symfony/console version (see symfony/console@9a4fcec and tags for minimum versions)

Confirmed if you run composer why symfony/console on box-project

humbug/box          3.x-dev  requires   symfony/console (^4.3.5 || ^5.2)
humbug/php-scoper   0.14.1   requires   symfony/console (^3.2 || ^4.0)
symfony/var-dumper  v5.3.8   conflicts  symfony/console (<4.4)

composer.lock told us that it's symfony/console v4.4.23 installed in box-project, and minimum should be 4.4.30 (related to symfony/console@9a4fcec)

Filed another PR to fix requirement checker #585

Somehow latest release 3.14.1 has no box.phar somehow

[theofidry]

Should be now working with 3.15
