strip out duplicate content from an array

I hope someone can help me out. I am looking for a way to strip out duplicate content from an array.

I have a post_type called catalogue, post_type called model and a post_type quality.
Within the post_type model i have a relationship field pointing to the quality and a relationship pointing to the catalogue.(post object) (the model belongs to a catalogue and is made from a certain quality)

So in the example below i am getting all the qualities that are being used in the models that have a certain catalogue number.

I am setting up an isotope filter so need to add them to a list. This works fine except it pics up duplicate qualities along the way. SO if i have 3 models that use the same qualite, the quality is added 3 times. Is there anyway to strip out duplicates. I can’t figure it out.

I hope you can help me. Thank you this is a great plugin by the way!!

<?php
function get_qualite_from_cata() {
			$modeles = get_posts(array(
			'post_type' => 'modele',
			'meta_query' => array(
							array(
							'key' => 'catalogue', // name of custom field
							'value' => '"' . get_the_ID() . '"', // matches exaclty "123", not just 123. This prevents a match for "1234"
							'compare' => 'LIKE'
							)
							)
					));

	if( $modeles ): 
		foreach( $modeles as $modele ):
		$qualite = get_field( 'qualite', $modele->ID); 
					?>
		<?php if( $qualite ): ?>
	<?php foreach( $qualite as $qualite ): 
					
	echo '<dd class="filtr" data-filter=".'.  $qualite->ID .'">'. get_the_title( $qualite->ID ) .'</dd>';
	?><?php endforeach; ?>
	<?php endif; ?>
			
	<?php endforeach; ?>
<?php endif; 

		}
// end function
?>

}
// end function
?>

To make it clearer this

<?php if( $qualite ): ?>
	<?php foreach( $posts as $post ): 
					
	echo '<dd class="filtr" data-filter=".'.  $post->ID .'">'. get_the_title( $post->ID ) .'</dd>';
	?><?php endforeach; ?>
	<?php endif; ?

is giving me multiple copies of the same. How can i strip the duplicates out? I have been looking at array_unique and DISTINCT but I can’t figure out how to implement this here.
I have currently implemented some jquery that removes the duplicates but i am not exactly happy about that solution. Any pointers. Thanks

Is $qualite a regular array or an associative array?

One idea would to be to store the value of each $qualite in a variable and check the new one against it before outputting it. Example:

$qualite = get_field( 'qualite', $modele->ID);
if( $qualite ):
$unique = '';
    foreach( $qualite as $qualite ): 
        if ( $unique != $qualite ) :
            echo '<dd class="filtr" data-filter=".'.  $qualite->ID . '">'.get_the_title( $qualite->ID ) .'</dd>';
        $unique = $qualite;
        else : endif;

    endforeach;
endif;
