If you need to only copy the post, you can use @ngearing's solution in https://stackoverflow.com/a/56437515/3480821

If you want to duplicate the post with its meta and terms as well, you can use the following function:

<?php

/**
 * Duplicates a post & its meta and returns the new duplicated Post ID.
 *
 * @param int $post_id The Post ID you want to clone.
 * @return int The duplicated Post ID.
 */
function duplicate_post(int $post_id): int
{
    $old_post = get_post($post_id);
    if (!$old_post) {
        // Invalid post ID, return early.
        return 0;
    }

    $title = $old_post->post_title;

    // Create new post array.
    $new_post = [
        'post_title'  => $title,
        'post_name'   => sanitize_title($title),
        'post_status' => 'draft',
        'post_type'   => $old_post->post_type,
    ];

    // Insert new post.
    $new_post_id = wp_insert_post($new_post);

    // Copy post meta.
    $post_meta = get_post_custom($post_id);
    foreach ($post_meta as $key => $values) {
        foreach ($values as $value) {
            add_post_meta($new_post_id, $key, maybe_unserialize($value));
        }
    }

    // Copy post taxonomies.
    $taxonomies = get_post_taxonomies($post_id);
    foreach ($taxonomies as $taxonomy) {
        $term_ids = wp_get_object_terms($post_id, $taxonomy, ['fields' => 'ids']);
        wp_set_object_terms($new_post_id, $term_ids, $taxonomy);
    }

    // Return new post ID.
    return $new_post_id;
}

I have also made this function available in a Github gist here.

You can use the wp_insert_post() function to duplicate a post.

You just need to remove the post ID from the data you pass to it, and Wordpress will create a new post instead of updating an existing one. E.g.

    $post_id = 1234;
    $post = (array) get_post( $post_id ); // Post to duplicate.
    unset($post['ID']); // Remove id, wp will create new post if not set.
    wp_insert_post($post);

Comments are stored in a different table. And are linked by the post ID. As the duplicate post will have a different ID the original comments will not be associated with it.

No, there does not exists such functionality like duplicate post in WordPress core.

To meet your requirement you can use this plugin : https://wordpress.org/plugins/post-duplicator/

This plugin duplicate the post but not comment. See there documentation
