Subject: Re: [PHP-DEV] private, protected, readonly, public
From: jason@ionzoft.com (Jason Garber)

Hello Marcus,

  class x
  {
     public readonly $xyz;
     protected readonly $abc;
  }

  Definitions:
  - public readonly    - outside class can only read, not write.
  - protected readonly - subclass can only read, not write.
  - private readonly   - does not make sense - do not support.

  How difficult would it be to build this into the PHP engine?
