how can i add class or span tag at sprintf?

Question

i hope to add span tag or class at sprintf

I want to enlarge the text size of the numbers in front of me. So I want to add span tag or class only to text in front of me.

my code is

            /**
             * Filters the product average rating.
             *
             * @since 1.10.0
             *
             * @param float $average_rating average rating
             * @param \WC_Product $product the product object
             */
            $average_rating = max( 0, (float) apply_filters( 'wc_product_reviews_pro_product_rating_average', $product->get_average_rating(), $product ) );

            $reviews_count  = max( 0, wc_product_reviews_pro_get_contributions_count( $product, 'review' ) );

            /* translators: Placeholders: %s - average rating stars count (float casted as string to avoid trailing zeroes), %d - 5 stars total (integer) -- (e.g "4.2 / 5 stars") */
            $reviews_label  = sprintf( __( '%s / %d', 'woocommerce-product-reviews-pro' ), $average_rating, 5 );

            ?>
            <h3><?php echo esc_html( $reviews_label ); ?></h3>

            <p><?php echo get_star_rating(); ?></p>

I tried many ways. https://stackoverflow.com/questions/45312511/adding-class-to-element-in-php-code I've taken a lot of reference to the above url

But all the results are printed like <span>4</span>/5. I don't want it to be in print.

Is there a good solution? thanks.

Actaully using esc_html won't help because it will escape any html character, so you have to depend on wp_kses so you can specify the accepted tags and there attributes, so no need then to escape the output. but you have to escape the values comming from DB, which in you case $average_rating. so your can be like this.

$accepted_tags  = array('strong'=>array());

$reviews_label  = wp_kses(
                        sprintf( 
                            __( '%s / %d', '<strong>woocommerce-product-reviews-pro</strong>' ), 
                            esc_html($average_rating), 
                            5 
                        ), 
                    $accepted_tags );

<h3><?php echo $reviews_label ; ?></h3>

Update

As i can see from your comment, You need to add tag to the %s, so you need to just change the $accepted_tags to:

$accepted_tags  = array('span'=>array());

anf the sprintf to:

sprintf( 
        __( '<span>%s</span> / %d', 'woocommerce-product-reviews-pro' ), 
        esc_html($average_rating), 
        5 
    ),
