How to skip duplicate data in foreach loop

I need help in removing or skipping duplicate data from foreach array, i try to use array_unique() but it doesn’t help.

here’s my code.

<?php
if(is_cart()){
    foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
        $term_name = get_the_terms( $cart_item['product_id'], 'product_cat' );

        foreach($term_name as $idterm){
            if($idterm->parent == 0){
                $parentcat = $idterm->description;
            }
            $term_prid = $idterm->term_id;
        }

        $rootId = end( get_ancestors( $term_prid, 'product_cat' ) );

        $root = get_term( $rootId, 'product_cat' );
        if(!empty($root->description)){
            echo '<div class="club-information"><div class="club-record"><p>'.$root->description.'</p></div></div>';
        }
    }
    if(!empty($parentcat)){
        echo '<div class="club-information"><div class="club-record"><p>'.$parentcat.'</p></div></div>';
    }
}
?>

if i have more than 2 products of same category in cart it repeat the same data, which should not.

this is what i get from print_r($term_prid)

91
91
13

How can i get

91 
13

Answer

Save the IDs you’ve seen in an array, and check against that.

if(is_cart()){
    $seen_ids = [];
    foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
        $term_name = get_the_terms( $cart_item['product_id'], 'product_cat' );

        foreach($term_name as $idterm){
            if (in_array($idterm->term_id, $seen_ids)) {
                continue;
            }
            $seen_ids[] = $idterm->term_id;

            if($idterm->parent == 0){
                $parentcat = $idterm->description;
            }

            $term_prid = $idterm->term_id;

        }

        $rootId = end( get_ancestors( $term_prid, 'product_cat' ) );
        $root = get_term( $rootId, 'product_cat' );
        if(!empty($root->description)){
            echo '<div class="club-information"><div class="club-record"><p>'.$root->description.'</p></div></div>';
        }
    }
    if(!empty($parentcat)){
        echo '<div class="club-information"><div class="club-record"><p>'.$parentcat.'</p></div></div>';
    }
}
