    Avoiding infinite loops:
    Calling this function within the loop will cause an infinite loop. For example, see the following code:

    while ( have_posts() ) : the_post();
    // Display post
    if ( have_posts() ) : // If this is the last post, the loop will start over
        // Do something if this isn't the last post
    endif;
endwhile;

    If you want to check if there are more posts in the current loop without this unfortunate side effect, you can use this function:

    In your functions.php file:

    /**
 * Check if a loop has any more posts left.
 *
 * @global $wp_query
 *
 * @return bool True if there are any more posts in this loop, false if not.
 */
function wpdocs_has_more_posts() {
  global $wp_query;
  return $wp_query->current_post + 1 < $wp_query->post_count;
}

    In your template file:

    while ( have_posts() ) : the_post();
    // Display post
    if ( wpdocs_has_more_posts() ) :
        // Do something if this isn't the last post
    endif;
endwhile;

    <?php if ( have_posts() ) : while( have_posts()  ) : the_post(); ?>
    <h1><?php the_title(); ?></h1>
    <a href="<?php the_permalink(); ?>">
        <?php the_post_thumbnail( 'full' ); ?>
    </a>
    <p><?php the_excerpt(); ?></p>
<?php endwhile; endif; ?>

    Output:
    Post title
    Post featured full size image (When anyone click on the image then open post single page)
    Post small description

    Example: if creating a custom WP_Query out of the standard WP loop context. This example uses have_posts() function extended from WP_Query:

    <?php
// Define args
$args = array('post_type' => 'custom_post_type');

// Execute query
$cpt_query = new WP_Query($args);

// Create cpt loop, with a have_posts() check!
if ($cpt_query->have_posts()) :
  while ($cpt_query->have_posts()) : $cpt_query->the_post(); ?>

    <?php the_title(); ?>

<?php endwhile;
endif; ?>
