This is what I'd do:
$sql = "SELECT disinct category FROM article ORDER BY category";
$r = mysql_query($sql);
while($cat = mysql_fetch_array($r))
{
$id = $cat['id'];
$sql = "SELECT * FROM article WHERE category='$id'";
$x = mysql_query($sql);
while($row = mysql_fetch_array($x))
{
// echo articles here
}
}
The permanent solution is to make a separate table called "categories" and then
do a join on the categoryID from the two tables.
