Question

If I have:

<?php
class SomeClass extends SomeOtherClass{
  private $access_code = 'TX9999';

  private static function SomeMethod(){

  }
}

?>

And do

<?
self::SomeMethod();
?>

how do I correctly access $access_code in ::SomeMethod()

More Info

What Im actually facing is more complex.

I have a class with methods that are and must remain static.
I know how to call other methods using self.

However across the class I have things that would ordinarily make sense as constants and variables.

I realise that I haven’t got an instance in the normal way and am looking for away to share variables between some of the static methods of the class, some are volatile, some fixed

Answer 1

This would do what you want; it creates an instance of itself first before being able to access the private instance variable $access_code.

$o = new self;
echo $o->access_code;

---

If you want a class variable instead of instance variable, you have to declare the $access_code like this:

private static $access_code = 'TX9999';

Then call it from the static method like this:

private static function SomeMethod()
{
    echo self::$access_code;
}

Btw, you can’t call ::SomeMethod() from outside the class. In order to do that, you need to make it public:

public static function SomeMethod() { ... }
