Using attributes with PHP < 8.0

[Mopolo]

Hi!

On the anouncement page it says that some of these attributes work on older versions of PHP if used on a single line (so that PHP thinks they are comments).

However if PHPStorm is configured to sync settings with this composer.json:

{
    "require": {
        "php": "^7.4 | ^8.0"
    },
    "autoload": {
        "psr-4": {
            "Acme\\": "src"
        }
    }
}

Then the attribute is shown with an error:

And the error:

At the same time the attribute works in other code:

Is that the indented behavior?

Hey. These attributes works for PHP < 8 as side effect of the fact that one-line version of attribute will be parsed as line comment in some cases, generally it's recommended to use them with PHP 8 version. Generally attributes is PHP 8 language feature and this inspection aims to hint users about that fact.

Hi thanks for the reply. I understand the behaviour it's just a shame since it explicitly says that it works in PHP 7.4 on the release page of PHPStorm: https://www.jetbrains.com/phpstorm/whatsnew/

These are PHPStorm specific attributes so it would make sens for them to work on lower versions (well they do but with a big red warning).

I'll just use them in PHP 8 instead. Thanks.

Bit late to the party, but it would be nice if these weren't marked as errors as it's valid PHP code. Are we able to disable that inspection? I can't find it if so.
