In PHP4 if you don't make use of $this in a class method then it can be
used as a static function.

PHP4 does not support static class vars, instead you need to use a
static function with a static variable.

<?php
class Auth
{
    function authenticate()
    {
        ...
    }

    function staticVar( $setValue=null )
    {
        static $myStaticVar = null;

        if( $setValue !== null )
        {
            $myStaticVar = $setValue;
        }

        return $myStaticVar;
    }
}
?>

Cheers,
Rob.
