PHP Code for “SAVE” in product page

Hi guys, i put php snipped code in my store but i have problem and need help.

The code show the symbol and the amount like this “You save: $20” but in my country the symbol is over the number like this “You save: 20 PLN”

Just need to replace the value of this code but i don’t know how i try everything.

function you_save_text_for_product() {
global $product;

// works for Simple and Variable type
$regular_price     = get_post_meta( $product->get_id(), '_regular_price', true ); // 36.32
$sale_price    = get_post_meta( $product->get_id(), '_sale_price', true ); // 24.99

if( !empty($sale_price) ) {

    $saved_amount      = $regular_price - $sale_price;
    $currency_symbol   = get_woocommerce_currency_symbol();

    $percentage = round( ( ( $regular_price - $sale_price ) / $regular_price ) * 100 );
    ?>
        <p class="you_save_price">You save: <?php echo $currency_symbol .''. number_format($saved_amount, 2, '.', ''); ?></p>           
    <?php       
} 

}
add_action( ‘woocommerce_single_product_summary’, ‘you_save_text_for_product’, 12 ); // hook priority
