I have a class called Randimg. Within that class, I have several methods. Within a few of those methods, I use the below code snippet:

$_SERVER['DOCUMENT_ROOT']

What would be the best way to assign the above code to a global variable/constant within the class?

Within the constructor for Randimg you could set a local protected variable:

class Randimg
{
  var $docroot = false;

  function Randimg ()
  {
    $this->docroot = $_SERVER['DOCUMENT_ROOT'];
  }

and then you can just reference $this->docroot from any of the Randimg methods.

In PHP 5 could you create $docroot as a protected class constant, but in PHP 4 the above will have to do.
