如何实现从数据库读取后重新从1到10排序

$query = "select * from software order by cnet_total_downloads limit 10";
$result = mysql_query($query) OR die(mysql_error());
while($row = mysql_fetch_array($result))
{
echo "X.".$row['software_name'];
}

想要的效果就是上面的X怎么变成1,2,3,4,5,6,7,8,9,10

最终显示
1. a
2. b
3. c
.
.
.
10.Z

这个1到10如何实现
[解决办法]

$query = "select * from software order by cnet_total_downloads limit 10";
$result = mysql_query($query) OR die(mysql_error());
while($row = mysql_fetch_array($result))
{
static $i=1;
echo "$i.".$row['software_name'];
$i++;
}

试下看能不能行
