How can I add a certain class to the ul based on how many images there are?

So when there is 2 images the ul get class"images one-photo" and when there are 5 images the ul gets the class class"images five-photo" and so on...

What I now have in code:

<?php if( have_rows('blog_item') ): ?>
 <?php while( have_rows('blog_item') ): the_row(); ?>

<ul class="images">
 <?php if( get_sub_field('photo-01') ): ?>
 <li><img src="https://www.website.com/<?php the_sub_field('photo-01'); ?>" alt="" /></li>
 <?php endif; ?>

 <?php if( get_sub_field('photo-02') ): ?>
 <li><img src="https://www.website.com/<?php the_sub_field('photo-02'); ?>" alt="" /></li>
 <?php endif; ?>

 <?php if( get_sub_field('photo-03') ): ?>
 <li><img src="https://www.website.com/<?php the_sub_field('photo-03'); ?>" alt="" /></li>
 <?php endif; ?>
</ul>
 <?php endwhile; ?>
<?php endif; ?>

Something like this would come to mind:

<?php
$count = 0;
$image_display = '';
for($i=1 ; $i <= 3; $i++)
 if( get_sub_field('photo-0'.$i) ):
 $count++; // count photos here
 $image_display .= '<li><img src="https://www.website.com/'.the_sub_field("photo-0".$i).'" alt="" /></li>';
 endif;

$class = '';
switch ($count) 
 case 1: $class = 'one-photo';break;
 case 2: $class = 'two-photo';break;
 case 3: $class = 'three-photo';break;
 case 4: $class = 'four-photo';break;
 case 5: $class = 'five-photo';break;


echo '<ul class="images '.$class.'">'. $image_display.'</ul>';
?>
