Hello there,

I'm quite new to OOP in PHP. Unfortunately, I'm forced to work with PHP4,
because my website is still hosted with this version.

I've made two classes (see below): "Product" and "ProductList".
Class "Product" has some properties, including an ID prop to store it's
database ID.
Class "ProductList" contains an array of "Product" objects.

My question is this:

Is there some fancy way to retrieve a Product object from the ProductList's
object by it's ID-property, without looping through the Products in the
object array?
(Please note: I need to find it by a property value, not by it's array
index!)

Thanks!
Ramon


== code ========================================

class ProductList {
var $m_oProductList = array();

function add ($oProduct) {
$this->m_oProductList[] =& $oProduct;
}

function getProductByID ($iID) {
return $this->m_oProductList[ ??? ]; <-- and this is where I got
stuck...
}
}


class Product {
var $m_iID;
var $m_sName;

function Product ($iID=0) {
$this->m_iID = $iID;
}

function setID ($iID) {
$this->m_iID = $iID;
}

function getID () {
return $this->m_iID;
}

function setName ($sName) {
$this->m_sName = $sName;
}

function getName () {
return $this->m_sName;
}
}
