I have a class called Randimg. Within that class, I have several

$_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.
