Call LABELS of selection field inside repeater

Here’s what I am currently seeing as a result of my code:

<?php
if( get_field('degrees') ) {
    echo '<strong>Degrees: </strong>'; 
    while ( have_rows('degrees') ) : the_row();
     $array[] = get_sub_field('degree_select'); 
    endwhile;
    $foo = implode(', ', $array);
	
    echo $foo;
}
?>

The sub_field “degree_select” is a selection field that has Labels and Values. I only want to call the Labels in a comma separated list.

Typically I would write something like:

<?php while (have_rows('degrees') ): the_row();
$value = get_sub_field('degree_select');
echo $value['label'];
endwhile; ?>

.. which works fine, but I haven’t been able to get it working using implode for this comma separated list yet. Any help would be greatly appreciated.

Thank you.

I figured out the solution. I was to use array_column which helped me focus on that single column of information.

<?php if( get_field('degrees') ) {
   while ( have_rows('degrees') ) : the_row();
      $array[] = get_sub_field('degree_select'); 
   endwhile;
   $foo = implode(', ', array_column($array, 'label'));
   echo $foo;
   }								
?>
