Count One Table's Rows From Multi Table Query

here are my tables (condensed)

FEEDS
feed_id
site_id

SITE
site_id
site_name

ARTICLES
article_id
feed_id
link

I want to create a query that returns the total number of articles for every site_id (which is unique in the SITE table). I have this:

PHP

$gsite = mysql_query("SELECT site.site_id, feeds.feed_id, COUNT(articles.article_id) AS acont FROM site,feeds,articles
WHERE feeds.site_id = site.site_id AND articles.feed_id = feeds.feed_id group by site.site_id", $connection)
or die(mysql_error());

The query does not use JOIN, ON and all that good stuff.

I just need the following variables to run through a loop:

site_id
the number of articles rows per site_id
