Description:
------------
I have never used mysql_insert_id() before, but I think its not too hard to get right. From what I know it will return "The ID generated for an AUTO_INCREMENT column by the previous query on success" as stated on php.net/manual.

When I run my insert query, which inserts multiple(10) rows, the mysql_insert_id only gives the 'first' id used and not the last id. In my code this is actually more useful to me, but I had to figure it out the hard way.

Is this a bug or a feature?

P.S. I'm using 5.3.0, but I checked and 5.3.1 doesn't mention this

Reproduce code:
---------------
$query = 'INSERT INTO player VALUES ';
foreach($data['players'] as $player){
	$query .= sprintf("(null, '%s', '%s', '%s', '%s', '%s', %s),", $stuff, $stuff, $stuff, $stuff, $stuff, $stuff);		
}
$query = substr($query,0,-1);//removes last comma
$result = mysql_query($query, $resource) or die(mysql_error());
$firstPlayerID = mysql_insert_id($resource);

Expected result:
----------------
10 players, starting at AUTO=1
result should be = 10

Actual result:
--------------
10 players, starting at AUTO=1
result is = 1
