PHP 8 compatibility

[remicollet]

Any plan ?

Hi @remicollet great question!

Tensor PHP is 100% PHP 8 compatible

Parts of the Tensor extension are built with Zephir which may or may not be PHP 8 compatible, I haven't tried it yet. As far as I know the Zephir people are working on PHP 8 compatibility in general.

https://github.com/phalcon/zephir/issues/2111

Have you tried compiling the extension on PHP 8?

Thanks again for the question and feel free to join us in our Telegram Channel https://t.me/RubixML

At least I see ice 1.8.0 which use zephyr and works with PHP 8

For this project, build fails

Nice @remicollet, it looks like Ice is using the php8-development branch to compile their Zephir source down to C. Maybe the same will work for us!

https://github.com/ice/framework/blob/dev/composer.json#L19

Ok, it looks like we can become PHP 8 compatible with the new updates to Zephir, however, we'll lose PHP 7.2, and 7.3 support. What I think we'll do is wait just a bit more while and then release a new minor version which requires PHP 7.4+ but works with PHP 8. How does that sound?

[marclaporte]

Happy retirement PHP 7.2, and 7.3, and thank you for your service.

[remicollet]

How does that sound?

No problem for me

[andrewdalpino]

Happy retirement PHP 7.2, and 7.3, and thank you for your service.

PHP 7.2, 7.3 ... you guys, it's been REAL

[Jeckerson]

Zephir is ready to be used for PHP8 since v0.13. Feel free to upgrade.
