constant.attributesRuleCannotRun

Code example

This error cannot be demonstrated with a simple code example because it depends on the PHP runtime version used to run PHPStan.

Why is it reported?

PHPStan needs PHP 8.5 or later as its runtime to check attributes on global constants. The analysed code uses attributes on a global constant (a feature available since PHP 8.5), but the PHP version running PHPStan itself is older than 8.5.

This is a limitation of the PHPStan runtime environment, not of the analysed code itself.

How to fix it

Run PHPStan with PHP 8.5 or later to enable checking attributes on global constants.
