PHP 8.4 Deprecation?

[andrewteg]

I get the following when testing a pretty basic setup on PHP 8.4.3. It looks like it's this deprecation (https://php.watch/versions/8.4/implicitly-marking-parameter-type-nullable-deprecated) and I'm wondering if there's a roadmap to make this PHP 8.4 compatible, or if I've done something wrong. Thanks.

Thanks!

Yes, the fix is very easy. But unfortunately, we still have to support PHP 7.0, for example for clients on Ubuntu with Ubuntu Expanded Security Maintenance (ESM).

In production, you should obviously disable deprecation warnings. But for development environments, our only choice right now may be to drop the type annotations (turning SomeClass $someParam = null into just $someParam = null) to get rid of the implicit null in the annotation, until we can drop PHP 7.0 support.

So for now, to keep PHP 7.0 support, we won’t be able to avoid this deprecation warning just yet.

But there is no reason you should be bothered by the messages, as it’s not an error, doesn’t break logic or behavior, and it’s not even in your own code where you need to care about it. So if you are distracted by the deprecation warnings, maybe consider suppressing them for this library.

For example, where you include the dependencies from Composer with

require __DIR__ . '/vendor/autoload.php';

consider adding a custom PHP error handler that suppresses only deprecation warnings that come from this library here, using the same base for the vendor directory with __DIR__ . '/vendor/:

\set_error_handler(function ($errno, $errstr, $errfile, $errline) {
    // if the error is a deprecation warning
    if ($errno & (\E_DEPRECATED | \E_USER_DEPRECATED)) {
        // if the error is a warning from third-party dependency 'PHP-Auth'
        if (\strpos(\str_replace('\\', '/', $errfile), \str_replace('\\', '/', (__DIR__ . '/vendor/delight-im/auth/'))) === 0) {

            // suppress the error
            return true;
        }
    }

    // let PHP's standard error handler handle the error
    return false;
});

First of all, thank you for this great authentication system!

Just for me to understand; so that means that till April of 2026 there is support for PHP 7.0? Apr 2032 will be the first version that starts from at least PHP 8.1 support? Can't this "problem" be solved with different versions?

When testing this issue, the deprecation errors only displayed after restarting php-fpm and apache. The reason was I needed to set opcache.enable=1 in php.ini. See php/php-src#16897

Also, other delight-im repos, like db, were throwing deprecation errors, so the code above from @ocram didn't catch everything. I just changed the search to /vendor/ in order to suppress for all 3rd party deprecations.
