php - Any suggestions how can I optimize this code? I need to translate some strings in 3 languages. Thanks

one text

Solution:

You could use variables to assign the language text in a switch statement to reduce the repitition of your current code:

switch(ICL_LANGUAGE_CODE) {
        case 'ru':
            $buyText = 'Купите еще на %s для бесплатной доставки';
            $continueText = 'Продолжить покупки';
        break;
        case 'tr':
            $buyText = 'Ücretsiz kargo için %s daha satın alın';
            $continueText = 'Alışverişe devam';
        break;
        default: //en
            $buyText = 'Buy %s worth products more to get free shipping';
            $continueText = 'Continue shopping';
        break;
    
    }
$buyText = sprintf($buyText, wc_price( $min_amount - $current ) );

You can then get rid of the if statements to output a single piece of code based on the variables above:

if (( $current < $min_amount )) {
        $buyText = sprintf($buyText, $min_amount - $current );
        $added_text = '<div class="woocommerce-message"><strong>'.$buyText.'</strong>'; // This is the message shown on the cart page
        $return_to = wc_get_page_permalink( 'shop' );
    
        $notice = sprintf( '%s<a class="button" href="%s">%s</a>', $added_text, esc_url( $return_to ), $continueText ); // This is the text shown below the notification. Link redirects to the shop page
        echo $notice;
    }

Here a slimmed down example with the wp specific functions removed so it will run in vanilla PHP: https://3v4l.org/C9MCJ
