Adding Formatted Numbers To A MySQL Select Array - php

Question

I'm building a simple music website which has a set of albums on the selection page. On the left will be a group of album covers, and on the right will be the related album title and band name. Each album will be given a number, which will be referenced in the title/band name. Kind of like on a magazine contents page.
So my SELECT statement looks like:
$albums_sql = "SELECT albums.*, bands.name FROM albums LEFT JOIN bands ON albums.band = bands.id LIMIT $offset, $album_limit";
$albums_res = mysqli_query($con, $albums_sql);
while($album = mysqli_fetch_assoc($albums_res)){
$album_id = $album["id"];
$album_added = $album["added"];
$album_band = $album["name"];
$album_title = $album["title"];
....
And my displayed title looks like:
<div class=\"listWords\">$album_number ... <strong>$album_band: $album_title</strong></div>
Now this displays:
... The Band Name: The Album Name
But I obviously want it to display:
01 ... The Band Name: The Album Name
How do I get it to display a 2 digit numeral value for each row that is selected from the table using PHP?
Here's where I imagine I should create a number:
$albums_sql = "SELECT albums.*, bands.name FROM albums LEFT JOIN bands ON albums.band = bands.id LIMIT $offset, $album_limit";
$albums_res = mysqli_query($con, $albums_sql);
while($album = mysqli_fetch_assoc($albums_res)){
$album_id = $album["id"];
$album_added = $album["added"];
$album_band = $album["name"];
$album_title = $album["title"];
....
$album_number = ( Create a number based on how many are selected from the abover select statement )

Answer 1

Can be as simple as
$i=0;
while($album = mysqli_fetch_assoc($albums_res)){
$album_number = $i++;
$album_id = $album["id"];
$album_added = $album["added"];
$album_band = $album["name"];
$album_title = $album["title"];
...
and then if you want 0 padded numbers
echo sprintf("%02d",$album_number);

Answer 2

Just declare a variable as a counter outside of the while loop, and increment at each iteration.
$album_index = 0;
while($album = mysqli_fetch_assoc($albums_res)){
$album_number = $album_index++;
$album_id = $album["id"];
$album_added = $album["added"];
$album_band = $album["name"];
$album_title = $album["title"];
