 * Hi. I don’t know PHP very well and I want to optimize this PHP snippet. In this
   code I’m creating the $image variable, which stores the data of the custom field“
   Immagine Grande”.
    What I want to optimize is the href attribute of the a element,
   which at the end repeats “get_post_meta…” . I would like to use string concatenation
   but I don’t know how to use it in PHP. Thank you for your help.
 *     ```
       <?php $image = get_post_meta($post->ID, 'Immagine Grande', true); if($image != '') : ?>
   
       <a href="<?php bloginfo('template_directory'); ?>/images/products/<?php echo get_post_meta($post->ID, 'Immagine Grande', true); ?>" rel="lightbox">
       <img src="<?php bloginfo('template_directory'); ?>/images/icons/zoom_24.png" alt="<?php _e("Immagine del Prodotto", "mytextdomain"); ?>" />
       </a>
   
       <?php endif; ?>
       ```

 * No more problems. I fixed it by myself after half an hour of experimenting!
