Taxonomy terms manipulation on node.tpl.php
Finally I did it as shown below (thanks SO):

  &lt;?php if (isset($node-&gt;field_my_taxonomy_term[LANGUAGE_NONE]) &amp;&amp; $node-&gt;field_my_taxonomy_term[LANGUAGE_NONE]): ?&gt;
    &lt;?php $allOf=''?&gt;
    &lt;?php foreach ($node-&gt;field_my_taxonomy_term[LANGUAGE_NONE] as $obj): ?&gt;
        &lt;?php $exp = explode (" ", $obj['taxonomy_term']-&gt;name);
            $exp_last = array_pop($exp);
            $eachOne = $exp_last .', ' .implode(' ', $exp);
            $allOf .= $eachOne . '&amp;nbsp;-&amp;nbsp;';
         ?&gt;
    &lt;?php endforeach; ?&gt;
    &lt;?php print trim($allOf, '&amp;nbsp;-&amp;nbsp;'); ?&gt;
  &lt;?php endif ?&gt;


This is working correctly.
