1. We can use the get_locale function:

   if (get_locale() == 'en_GB') {
       // drink tea
   }

2. pll_current_language

   Returns the current language

   Usage:

   pll_current_language( $value ); 
   

   • $value => (optional) either name or locale or slug, defaults to slug

   returns either the full
   name, or the WordPress locale (just as the WordPress core function
   ‘get_locale’ or the slug ( 2-letters code) of the current language.

3. To show current language, you can use:

    <?php echo $lang=get_bloginfo("language"); ?>
   

   Plain and simple

5. This plugin is documented rather good in https://polylang.wordpress.com/documentation.

   Switching post language

   The developers documentation states the following logic as a means to generate URL’s for different translations of the same post

   <?php while ( have_posts() ) : the_post(); ?>
   <ul class='translations'><?php pll_the_languages(array('post_id' =>; $post->ID)); ?></ul>
   <?php the_content(); ?>
   <?php endwhile; ?>
   

   If you want more influence on what is rendered, inspet pll_the_languages function and copy it’s behaviour to your own output implementation

   Switching site language

   As you want buttons to switch language, this page: https://polylang.wordpress.com/documentation/frequently-asked-questions/the-language-switcher/ will give you the required info.

   An implementation example:

   <ul><?php pll_the_languages();?></ul>
   

   Then style with CSS to create buttons, flags or whatever you want.
   It is also possible to use a widget for this, provided by te plugin

   Getting current language

   All plugins functions are explained here: https://polylang.wordpress.com/documentation/documentation-for-developers/functions-reference/

   In this case use:

   pll_current_language();

6. I use something like this:

   <?php 
   
   $lang = get_bloginfo("language"); 
   
   if ($lang == 'fr-FR') : ?>
   
      <p>Bienvenue!</p>
   
   <?php endif; ?>

                       $currentpage = $_SERVER['REQUEST_URI'];
                       $eep=explode('/',$currentpage);
                       $ln=$eep[1];
                       if (in_array("en", $eep))
                       {
                           $lan='en';
                       }
                       if (in_array("es", $eep))
                       {
                           $lan='es';
                       }
                   ?>
