Convert sql php script to coldfusion - php

Question

we have a script that has been provided from our developers for php to generate a best sellers list from our database, however we need it to be in coldfusion!
Is there a simple way to convert or will this need rewriting completely?
Thanks in advance for any advice :-)
// // ---------- // Get Top Selling Products (by sku) // ---------- //
function CWgetBestSelling($max_products=5, $sub_ids=0)
{
$productQuery = '';
$returnQuery = '';
$idList = '0';
$itemsToAdd = '';
if (!is_numeric($idList[0])) {
$idList = '0';
}
$q_productQuery = mysql_query( "
SELECT count(*) as prod_counter,
p.product_id,
p.product_name,
p.product_preview_description,
p.product_date_modified
FROM cw_products p
INNER JOIN cw_order_skus o
INNER JOIN cw_skus s
WHERE o.ordersku_sku = s.sku_id
AND s.sku_product_id = p.product_id

AND NOT p.product_archive = 1

LIMIT ".$max_products
,$_ENV["request.cwapp"]["db_link"]);
$productQuery = array();
while ($qd = mysql_fetch_assoc($q_productQuery)) {
$productQuery[] = $qd;
}
// add values to list
foreach ($productQuery as $values) {
$idList = $values['product_id'] . "," . $idList;
}
// if not enough results, fill in from sub_ids
if (count($productQuery) < $max_products) {
// number needed
$itemsToAdd = $max_products - count($productQuery);
for ($i = 1; $i <= $itemsToAdd; $i++) {
if (substr_count($sub_ids, ',') >= $i) {
$idListArray = explode(',', $sub_ids);
$idList .= "," . $idListArray[$i];
}
}
$q_resultsQuery = mysql_query("

Code conversion questions don't tend to stay open long because they're viewed as lazy. So, Here are some references to get you started. I'm no PHP pro but after a quick glance at your code I think this list of links will give you a good head start.
CFFunction
CFQuery
CFArgument
valueList()
CFLoop
CFif
In the interest of not doing your work for you and give you the opportunity to learn, I'll provide some samples but not the entire code so you get an idea where your PHP fits into CF. This is also the tag version, not the script version.
<cffunction name = "CWgetBestSelling" ...>
<cfargument name = "max_products" default = "5" ...>
<cfargument ...>
<cfset var local.productQuery = "">
<cfset var local.returnQuery = "">
<cfset ...>
<cfset ...>
<cfquery name = "q_productQuery " datasource = "yourDatasource">
SELECT
count(*) as prod_counter,
p.product_id,
p.product_name,
p.product_preview_description,
p.product_date_modified
FROM
cw_products p
INNER JOIN cw_order_skus o
INNER JOIN cw_skus s
WHERE
o.ordersku_sku = s.sku_id
AND s.sku_product_id = p.product_id
AND NOT p.product_on_web = 0
AND NOT p.product_archive = 1
AND NOT s.sku_on_web = 0
GROUP BY
product_id
ORDER BY
prod_counter DESC
LIMIT #arguments.max_products#
</cfquery>
...
...
...
<cfreturn yourReturnVariable>
</cffunction>
