The Attribute attribute

(PHP 8)

Attributes offer the ability to add structured, machine-readable metadata information on declarations in code: Classes, methods, functions, parameters, properties and class constants can be the target of an attribute. The metadata defined by attributes can then be inspected at runtime using the Reflection APIs. Attributes could therefore be thought of as a configuration language embedded directly into code.

#[\Attribute]
final class Attribute {

/* Константи */

const int TARGET_CLASS;

const int TARGET_FUNCTION;

const int TARGET_METHOD;

const int TARGET_PROPERTY;

const int TARGET_CLASS_CONSTANT;

const int TARGET_PARAMETER;

const int TARGET_CONSTANT;

const int TARGET_ALL;

const int IS_REPEATABLE;

/* Властивості */

public int $flags;

/* Методи */

public function __construct(int $flags = Attribute::TARGET_ALL)

}
