Support for PHP 8.0

[rvitaliy]

Hi, PHP 8.0 is planned for release in november 2020. It would be nice to see Magento 2.4 support it on release date.
Today the alpha1 is already available, so we can start to test it in CI tests.

@rvitaliy : Thank you for your report. For GitHub issue tracker is for Magento core technical issues only
Kindly refer to Community Forums or Magento Stack Exchange for technical questions, feature requests, etc.

[rvitaliy]

This is a technical problem, in November we could not use the new version of PHP because your platform will be obsolete again.

I see that time passes but your bad habits don't change. see #27227
If this is your approach to troubleshooting, I can't wait to stop using Magento.

Good job, bya!

Hello @rvitaliy

Thank you for your question!

Let me please provide some clarification.

For now, I have not heard during internal meetings and discuss any future plans for PHP 8.0 support.

But I am sure as soon as Magneto will have any roadmap/plans for this track, it will be announced through public media channels.

This public GitHub issue tracker is aimed at issues/bugs/improvements that ready to work - something that can be taken by any community member and fixing(creating PR).

This issue report looks like an open question that should be discussed.
I mean, it does not just task that ready to work but big and complex Story/Epic.

I would recommend to raise this topic/question and discuss in the next channels first:

• Community Forums
• Magento Stack Exchange
• or in public Magento Slack Channels

Also, I do not see any reason to keep this issue report open.
Because it will be not possible to share updates about this track in time as a comment or links here. As I mentioned such news will be announced using other channels.

I think Magento LTS (OpenMage) will support PHP 8 first as it's more active. Or just use WooCommerce instead. M2 updates are kinda slow and until today PHP 7.4.4 is still not supported. O___O. PHP 7.3 EOL is in 4 months (December 6, 2020).

Hi there, let me provide additional input here.

We are seriously considering PHP 8.0 support for Magento, and some of the features would be especially handy for Magento.
Now we are trying to fit compatibility with PHP 8.0 to our very tight product backlog :)

Currently, we support PHP 7.4 / 7.3, and taking into account that active support of 7.3 will end soon, we switched our CI/CD infrastructure towards 7.4.*

Usually in Magento when we release a major version of the platform we keep supporting throughout all patch releases (in the scope of that major version) all the PHP versions which were actively supported at the time when Magento major release was out. This is done to prevent possible BiC for patch release upgrades.

Also, we separate "support" and "compatibility" in terms of Magento.
Support - is when you are able to use version-specific features, which did not exist before
Compatibility - is when we make sure that everything works as expected, but we don't use features that appeared only in this version and were previously absent.

So, if we would find a way to introduce "Compatibility" of Magento 2.4 with PHP 8.0 - we would definitely do this. Moreover, we really encourage you to help us finding a way of doing this. Thus, all the PRs which provide this compatibility for Magento 2.4 will have a very high priority for us, and we will consider them thoroughly.

@bryanveIoso I did not hear anything about problems with PHP 7.4.4 - could you provide more background here?

[hostep]

@maghamed: @bryanveIoso commented on 7 July, so before Magento 2.4.0 was released (20 July), at that time no Magento versions were out with support for PHP 7.4 😉

Thanks for the extra information though!

[ihor-sviziev]

I will re-open this issue, as it wasn't resolved yet, there is no php 8 support.

[ilnytskyi]

Has anyone here already tried to setup a preload feature from 7.4 ?

[ihor-sviziev]

Update: we already have php 8.0 beta3, would be good at least to try run magento on it.

@ilnytskyi no, I don't, but would be good to see some info about it!

[rvitaliy]

FYI: https://www.php.net/ChangeLog-8.php#8.0.0

[Alex88-hub]

I've tested PHP 8 performance on Magento 2 and compare the results with PHP 7.3. Here it is

https://onilab.com/blog/php-7-vs-php-8/

The bottomline: the PHP 8 JIT is far from being useful in terms of improving the Magento 2 web application performance. However, it is fair to say that the feature perfectly copes with its tasks on simple code.

[rvitaliy]

@Alex88-hub
It's not just about performance!
With PHP 8, several improvements have been introduced in the language syntax that help improve the maintainability of the code.
For more information: https://stitcher.io/blog/new-in-php-8

I think it's a real shame that we can't take advantage of them yet.

[markshust]

FYI I just published a new Docker image for PHP 8.0 at https://github.com/markshust/docker-magento/tree/master/images/php/8.0

You can use the standard docker-compose setup at https://github.com/markshust/docker-magento and install Magento as usual. After it's installed, update the docker-compose.dev.yml file to use the new image/tag:
markoshust/magento-php:8.0-fpm-develop

I hope this helps out those who want to test Magento 2 on PHP 8. It should be very easy & simple to get an instance up & running that is easily replicable to diagnose/test issues.

[EmperorKonstantin]

I still feel like they may wait for Magento 3... Typing everything is a lot of work and the core codebase is sprawling at this point. Plus PWA Studio and Venia is coming... so any PHP they static-type for the frontend will be wasted.

[JosephLeedy]

@EmperorKonstantin Rector would probably help with that.

[EmperorKonstantin]

@JosephLeedy I'm not familiar with Rector, but I also hope that they use TypeScript in Magento 3 PWA Studio.

[hostep]

They are working on it on this branch should you be curious: https://github.com/magento/magento2/tree/php8-develop

Tickets around this can be seen over here: https://github.com/magento/magento2/projects/31

[EmperorKonstantin]

@hostep You're a champ! Yay! I see types!

[stale]

This issue has been automatically marked as stale because it has not had recent activity. It will be closed after 14 days if no further activity occurs. Is this issue still relevant? If so, what is blocking it? Is there anything you can do to help move it forward? Thank you for your contributions!

[ihor-sviziev]

This definitely should be open, as magento already have php 8 project.

[rvitaliy]

don't forget to allow php 8.1 🙏🚀
release date Nov 25 2021

[fascinosum]

hi everyone,
I would recommend to look at 11c679b
We are still working on the leftovers, but most of the scenarios are already green
And this is not the final destination 😉

[andrewbess]

Closed, because Magento2 is compatibility with PHP 8.0 on platform-health branch.

[hostep]

Out of curiosity: Magento 2.4.4 will ship with support for PHP 8.1, but will it also still be compatible with older versions of PHP, like 8.0 and 7.4? Based on the commit mentioned above, I would assume it will?

[fascinosum]

Hi @hostep, you can find information about supported versions on the DevDocs System Requirements page
Magento OS 2.4.4 will not have PHP 8.0 as a supported version. PHP 7.4 will have limited support - mostly provides the ability to upgrade from the previous versions
