    For your code to work, it should look like this. (replace $post_id with your post id variable)

    <?php
    require_once 'wp-load.php';
    require_once ABSPATH . '/wp-admin/includes/taxonomy.php';
    include_once 'wp-content/plugins/acf351/acf.php';
    // check if the repeater field has rows of data
    if( have_rows('ddw' , $post_id) ):
        // loop through the rows of data
        while ( have_rows('ddw', $post_id) ) : the_row();
    
            // display a sub field value
           echo get_sub_field('op1');
    
        endwhile;
    else :
        echo 'no rows found';
    endif;
    ?>
    

    You can find code samples here for all scenarios like without loop or for all posts with post ID. Try https://www.advancedcustomfields.com/resources/code-examples/
