Constant class in php

Question

I somehow heard well that I have one class with all your application constants, so you only have one location with all your constants.

I tried to do it as follows:

class constants{
    define("EH_MAILER",1);
 }

and

 class constants{
         const EH_MAILER =1;
  }

But in both cases this does not work. Any suggestions?

Answer 1

In the current version of PHP, this is the way to do this:

class constants
{
   const EH_MAILER = 1;
}

$mailer = constants::EH_MAILER

Starting with PHP 5.3, the best way to do this. Namespaces.

consts.php

<?php
namespace constants
const EH_MAILER = 1

...

other.php

<?php
include_once(consts.php)

$mailer = \constants\EH_MAILER
