Categories display

Hi!

Thank you so much. I’m getting closer 😉
So I removed some of the code and now I have it in a row.
How can I add a comma in between genres, but not on the last one?
For example: Reggae, Rock, Pop
But not: Reggae, Rock, Pop,

Hope it makes sense 😉

Here’s the code I have now, after I removed some of the stuff from the original code:

<?php
/* @var $EM_Event EM_Event */
$count_cats = count($EM_Event->get_categories()->categories) > 0;
if( $count_cats > 0 ){
	?>
	
		<?php foreach($EM_Event->get_categories() as $EM_Category): ?>
			<?php echo $EM_Category->output("#_CATEGORYLINK"); ?>
		<?php endforeach; ?>
	
	<?php	
}else{
	echo get_option ( 'dbem_no_categories_message' );
}
