[Plugin: Posts 2 Posts] Displaying connected posts as comma separated list

This is probably a noob questions, but I’m using the Posts 2 Posts plugin. I’m trying to display the connected posts as a comma separated list, instead of an unordered, bulleted list.

Here is the code I began with:

<?php
// Find connected pages
$connected = new WP_Query( array(
  'connected_type' => 'event_to_team',
  'connected_items' => get_queried_object(),
  'nopaging' => true,
) );

// Display connected pages
if ( $connected->have_posts() ) :
?>
<h3>Featuring:</h3>
<ul>
<?php while ( $connected->have_posts() ) : $connected->the_post(); ?>
    <li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
<?php endwhile; ?>
</ul>

<?php
// Prevent weirdness
wp_reset_postdata();

endif;
?>

The above code is copied directly from the Plugin’s documentation.

I edited it to this:

<?php
			// Find connected pages
			$connected = new WP_Query( array(
  			'connected_type' => 'event_to_team',
  			'connected_items' => get_queried_object(),
  			'nopaging' => true,
			) );

			// Display connected pages
			if ( $connected->have_posts() ) :
			?>
			<h3>Featuring: <?php while ( $connected->have_posts() ) : $connected->the_post(); ?><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>

			<?php endwhile; ?>

			<?php
			// Prevent weirdness
			wp_reset_postdata();

			endif;
			?>

Now the connected posts aren’t showing up as a list, but there is still a <br> between them. I’m attempting to get them to show up next to each other, separated by commas.

I think the fix is simple, but I’m fairly new to PHP and can’t get it to behave like I want!

Any help would be awesome.

Thanks all!
