Am new to PHP, and OOP but.... Is it possible to over use Constants? const = "77"; define("CONTACT_URL", "localhost/contact.html?"); Specially in OOP?.... What about something like current Customer ID, status, current loaded URL? .... I changes from Page load to page load but it is constant during a page load These things are retrieves and validated at very start of a page load. I am just wondering why I don't see more scrips with Constants
