سلام دوست عزیز

تعریف پراپرتی جداگونه مرسوم‌تر برای این مورد به خاطر اینکه خوانایی بیشتری داره، حتی در فریمورک symphony اومده تمام http status کد‌ها رو به صورت پراپرتی تعرف کرده!

در php 8.1 هم قابلیت enum‌ها اومد که خیلی از این موارد رو میشه با اون تعریف کرد که عالیه

گشتم براتون فایلش رو پیدا کردم

نکته جالبش هم اینه که خیلی از فریمورک‌ها از همین فایل استفاده میکنن
