一个do-while循环中的Simplexml计数

Question

I am trying to do a simplexml count inside a do-while loop, yes its simple but the count is not correct as it is inside 2 loops. Is there a easier way to do the count?

$query_fl = "SELECT * FROM table";
$fl = mysql_query($query_fl, $rf) or die(mysql_error());
$row_fl = mysql_fetch_assoc($fl);

do {
    $xml = $row_fl['fu'];
    $xmlDoc = new DOMDocument();
    $xmlDoc->load($xml);

    $rss = simplexml_load_file($xml);
    $items = $rss->channel->item;

    foreach($items as $item){
        echo $rss->channel->title;
        echo $feed_count."<BR>";
        $feed_count++;
    }

    $feed_count=1;

} while ($row_fl = mysql_fetch_assoc($fl)); 

------------- The output is like this

Feed 1 - Count-1
Feed 1 - Count-2
Feed 1 - Count-3
Feed 1 - Count-4
Feed 1 - Count-5

Feed 2 - Count- 1
Feed 2 - Count- 2
Feed 2 - Count- 3
...
..

--------------- I want the output as

   Feed 1 - Count-5
   Feed 2 - Count-3

You should be using mysqli instead of mysql_* as that is now depricated, but moving on... You have a couple of options, either:

1) move $feed_count=1; to before the do loop for a single count of all items.

or

2) make an array of counts for the foreach loop, incrementing the array index each time you exit the foreach loop. This will give you an array of counts for your items. If you use a key derived from an item variable eg its name, then you can count the number of occurences of an item type, even if they are not all together in your xml.
