File path without domain name from wp_get_attachment_url()

1. You can really easily explode it by / and then take the part with index 3. Example

   $url = wp_get_attachment_url(id); //id is file's id
   $urllocal = explode(site_url(), $url)[1]; //output local path

2. Here is the WordPress way using WordPress functions (avoid hacking):

   $fullsize_path = get_attached_file( $attachment_id ); // Full path
   $filename_only = basename( get_attached_file( $attachment_id ) ); // Just the file name
   

   WordPress has tons of functions, so first try to find the function on the docs: https://developer.wordpress.org/reference/functions/get_attached_file/

3. You can use PHP’s function explode.

   Here is the code:

       <?php
            $image_url = wp_get_attachment_url( 9 ); //ID of your attachment
            $my_image_url = explode('/',$image_url,4);
            echo $my_image_url[3];
       ?>

4. You can implode your entire url on / and array_slice from the end, then implode it back in on /.

   $url = wp_get_attachment_url($item->ID); //id is file's id
   $url_relative = implode(array_slice(explode('/', $url),-3,3),'/');
   //Returns: 2019/08/image.jpg
   

   That way if your WordPress is on a subdomain or localhost or the images are on S3 it won’t crash.
