Usage

The Provider class provides a method that returns a ReflectionAttribute. This works the same way in php7/8.

Notice

• Performance is low
• Attributes are cached per identifier if a PSR16 is specified
• Abstract syntax tree is cached per filename
• There are minute differences in __CLASS__ of anonymous classes
• Not support continuous line attribute (e.g. #[Attribute] private $property)
• Attribute::$target constraint is a runtime error (in php8 it is compile time)
