i added __set() to my original class, now i can do cool stuff, like this:

    $a = ArrayClass::simpleFactory(getArray())->{'a'} = 5;

which allows retrieval of the array, and modification (or access) to a given
member, in a single statement.

<?php
class ArrayClass {
    private $theArray = array();

    private function __construct($theArray) {
        $this->theArray = $theArray;
    }

    public static function simpleFactory($theArray) {
        return new self($theArray);
    }

    public function __get($member) {
        if(array_key_exists($this->theArray, $member)) {
            return $this->theArray[$member];
        }
        return null;
    }

    public function __set($member, $value) {
        $this->theArray[$member] = $value;
    }
}

function getArray() {
    return array(
        'a' => 1,
        'b' => 2
    );
}

$a = ArrayClass::simpleFactory(getArray())->{'a'} = 5;
var_dump($a);
?>

maybe boring to some (or many :D) but as the first time around, i just
thought it was cool and id share.
