回答1:

Why don't you just echo $directory below the <img> tag?

<tr>
   <?php foreach ($imgs as $img): ?>
   <td>
      <a href="<?php echo $img ?>" target="_blank">
         <img class="shadow1" name="field-name" src="<?php echo $img ?>thumb.jpeg" width=165 height=135 />
      </a>
      <p><?php echo basename($directory); ?></p>
   </td>
   <?php endforeach; ?>
</tr>

Do you not have access to this parameter in your current scope? Another option is:

<p><?php echo basename(pathinfo($img, PATHINFO_DIRNAME)); ?></p>

回答2:

echo  basename(realpath('./'));

realpath:

realpath() expands all symbolic links and resolves references to '/./', '/../' and extra '/' characters in the input path and return the canonicalized absolute pathname.

and

basename:

Given a string containing the path to a file or directory, this function will return the trailing name component.

Refer basename and realpath on Official site.
