PHP8 compatibility and installation via Composer

[sboerrigter]

Hi There! 👋

Are the "WordPress SEO" and "WordPress SEO Premium" plugins compatible with PHP 8?

I see that the version constraints in composer.json are set to "^5.6.20||^7.0", so I cannot install these plugins via Composer. Can you please update these version constraints if the plugins are compatible with PHP 8? And if they are not, is there an expected date when they will be?

Thanks in advance!

Used versions

• WordPress version: 5.7
• Yoast SEO version: 16.1.1
• Yoast SEO Premium version: 16.1
• PHP version: 8.0.3

Hi @sboerrigter . The plugins themselves are compatible with PHP 8.0. However, the composer process isn't and still needs to be ran with PHP 7.x. I believe it's something that's still being worked on and I'm not really sure anymore what the reason(s) are/were. But they were substantial enough that we couldn't just change the requirements in the json file.

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - yoast/wordpress-seo-premium[16.0, ..., 16.9.0] require php ^5.6.20||^7.0 -> your php version (8.0.11) does not satisfy that requirement.
    - Root composer.json requires yoast/wordpress-seo-premium ^16.0 -> satisfiable by yoast/wordpress-seo-premium[16.0, ..., 16.9.0].

The plugin still needs to be build on 7.x. There are no updates on PHP 8.0 progression.

And just to clarify for others; the plugin does work on PHP8. It's the composer building that needs to be done on 7.x.

Thanks.

That's a big odd....build on 7.x for use on 8.x?

FWIW, that creates a LOT of work when doing auto-deployments. It would be great if you could get on with testing and building via standard methods.

PHP 8.x has officially been out for a year now...

As an addition for anyone that this is affecting, there's a workaround in composer that I was not privy to.

Given that @Djennez said that Yoast is PHP 8.0 compatible, I felt comfortable doing a platform override.

Adding this to my composer worked perfectly.

    "config": {
        "platform": {
            "php": "7.4"
        }
    }
