Why not use the property value *as* the array index.

function add(&$oProduct, $id=false) {
if ($id===false) {
$id=$oProduct->m_iID;
} else {
$oProduct->m_iID->setID($id);
}
$this->m_oProduct[$id]=$oProduct;
}

(I think the reference operator is redundant - like Perl, PHP arrays only
seem to hold scalars, so the value is assigned to the array by reference).
