Need help with one line if php/html

[hausarzt]

Hey folks.
I want to add an extra line of code to my wordpress site, but I can't fgure out the correct code. Maybe someone can help me?

Every post has a featured image. I want to add a line of code, to that the the direct link to the featured image appears as a link in the theme.
Must be something like

<a href='$postthumbnail-whatever-url' title='$thumbnail-title-or-so' target="_blank">CLICK HERE</a>

Any helpers?

Try it like this

<a href='<?php echo $postthumbnail; ?>-whatever-url' title='<?php echo $thumbnail; ?>-title-or-so' target="_blank">CLICK HERE</a>

If you mean this

<a href='<?php echo $postthumbnail; ?>' title='<?php echo $thumbnail; ?>' target="_blank">CLICK HERE</a>

the answer is no.
This code points to the post-url. A need to point it to the post-thumbnail-url.
But we are getting closer.

// outside the loop

    $post = get_post(99);
    $thumb_url = get_the_post_thumbnail_url($post->ID,'full'); 

    echo '<a href="'.esc_url($thumb_url).'">Click Here</a>';

// inside the WP loop

    while ( have_posts() ) {
        the_post(); 
        $thumb_url = get_the_post_thumbnail_url(get_the_ID(),'full'); 
        echo '<a href="'.esc_url($thumb_url).'">Click here</a>';
    endwhile;
