Support PHP 8

Summary

PHP 8.0.0 was released yesterday: https://www.php.net/archive/2020.php#2020-11-26-3

I will need to update some roles to support it, but it would be nice to be able to support it, and probably bump the default version of PHP to 7.4 now.

Will there be next release with PHP 8 support?

[geerlingguy]

@kom177 - As much as I would like to do it (I'm already using PHP 8 in some systems elsewhere), Drupal itself doesn't yet support PHP 8 :(

See: geerlingguy/drupal-container#32 and https://www.drupal.org/project/drupal/issues/3156651

"PHP 8 is supported from Drupal 9.1.0"

Hmm... the last time I tried installing it (June) I was running into errors. Maybe it was Drush or some other dependency that still wasn't compatible?

[kom177]

I've stress-tested production site on PHP 8.0.3 and everything worked fine in a week (D9.1.10, D9.2.0 and D9.2.2, core-recommended project with more than 50 contrib modules). But Drush is configured to run under PHP 7.3. I'll try to reconfigure it.
UPD. I've changed all PHPs on remote server from 7.4 to 8.0 (for site on D9.2.2, CLI and aliases for drush and composer). Everything seems to work "as designed".

[kom177]

What could we do manually to enable PHP 8 support?

[geerlingguy]

The php-versions role supports PHP 8, so technically if you're on Ubuntu 18.04 or 20.04, or Debian 10/11, you could set php_version to 8.0 or maybe 8.1 (haven't tried that) and it should work... https://github.com/geerlingguy/ansible-role-php-versions

Jeff, thanks, everything works!
(For those who want to switch to PHP 8.0 - don't forget to replace files from release 6.0.4 to very last dev version in provisioning folder).

For new projects and D9 PHP 8 is recommended: https://www.drupal.org/docs/system-requirements/php-requirements

Would be nice to at least have instructions how to get PHP 8.0 provisioned in DrupalVM.

1. Download latest drupalvm code https://github.com/geerlingguy/drupal-vm/archive/refs/heads/master.zip and use it as a whole, or replace your provisioning folder
2. Change in provisioning/roles/geerlingguy.php-versions/defaults/main.yml php_version: '7.4' to '8.0'
3. Change in your config.yml php_version: "7.4" to "8.0"
4. Vagrant reload --provision, or better vagrant destroy / vagrant up
5. Enjoy

Actually this was (approximately) what I did:

1. Change base box in config.yml: vagrant_box: geerlingguy/ubuntu2004. Just to get the PHP8 from Ubuntu repo.
2. Change the php_version: "8.0"
3. Add the role to installed_extras: - php-versions
4. Add the php-versions role: ansible-galaxy install --roles-path /your/projects/drupal-vm/provisioning/roles geerlingguy.php-versions
5. Add a task like provisioning/tasks/install-php8.yml that is like this
   `- name: Include geerlingguy.php-versions role

include_role:

name: geerlingguy.php-versions

when: '"php-versions" in installed_extras'`

6. vagrant up --provision

Looks like it's working but I think only changing the php_version: "8.0" could be enough. :)

Hi @TipiT
Glad to hear that you were able to get it working. Will it be possible for your to share a repo where it is working with all the configuration changes in a single commit?

I am kind of struggling to place which to where.

Thanks.
