Taxonomy terms manipulation on node.tpl.php

Question

I wanted to print taxonomy terms on my custom node-mytype.tpl.php but what I want is not to print all the terms as they are.

Each of these terms consists of 2-3 words. And I want to manipulate the terms as below:

term1: word1 word2 word3

I want to print this as:

word3, word1 word2

If a node has one term it's easy and I can do this as below (of course there can be some other better way to do this):

inside node-mytype.tpl.php:

<?php if (!empty($node->field_my_taxonomy_term)) { ?>

    <?php $aut = ($node->field_my_taxonomy_term['und']['0']['taxonomy_term']->name); ?>
    <?php $exp = explode(" ", $aut); ?>     

    <?php if (count($exp) == 2) {?>
    <?php print ($exp[1]); print t(", "); print ($exp[0]); print t(", "); ?>

    <?php } elseif (count($exp) == 3) {?>
    <?php print ($exp[2]); print t(", "); print ($exp[0]); print t(" "); print ($exp[1]); print t(", "); ?>
    <?php }?>

I want to print multiple terms as above. For example:

term1: word1 word2 word3

term2: word4 word5 word6

should be printed as that:

word3, word1 word2 - word6, word4 word5

I have this:

   <?php $str = ''; ?>
        <?php if (isset($node->field_my_taxonomy_term[LANGUAGE_NONE]) && $node->field_my_taxonomy_term[LANGUAGE_NONE]): ?>

        <?php foreach ($node->field_my_taxonomy_term[LANGUAGE_NONE] as $obj): ?>
        <?php $str .= l($obj['taxonomy_term']->name, 'taxonomy/term/' . $obj['tid']) . '&nbsp;-&nbsp;'; ?>
        <?php endforeach ?>

        <?php print trim($str, '-&nbsp;'); ?>
   <?php endif ?>

The below code prints the terms as that:

word1 word2 word3 - word4 word5 word6

What code should I use here to print the terms as I wanted?

word3, word1 word2 - word6, word4 word5

Answer 1

Finally I did it as shown below (thanks SO):

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

This is working correctly.

<?php $str = ''; $terms = array();?>
<?php if (isset($node->field_my_taxonomy_term[LANGUAGE_NONE]) && $node->field_my_taxonomy_term[LANGUAGE_NONE]): ?>

<?php foreach ($node->field_my_taxonomy_term[LANGUAGE_NONE] as $obj): ?>
  <?php $terms[] = $obj;?>
<?php endforeach ?>

<?php 
   $str .= l($term[2]['taxonomy_term']->name, 'taxonomy/term/' . $term[2]['tid']) . ', ';
   $str .= l($term[0]['taxonomy_term']->name, 'taxonomy/term/' . $term[0]['tid']) . ' '; 
   $str .= l($term[1]['taxonomy_term']->name, 'taxonomy/term/' . $term[1]['tid']) . ' - ';
   $str .= l($term[5]['taxonomy_term']->name, 'taxonomy/term/' . $term[5]['tid']) . ', ';
   $str .= l($term[3]['taxonomy_term']->name, 'taxonomy/term/' . $term[3]['tid']) . ' ';
   $str .= l($term[4]['taxonomy_term']->name, 'taxonomy/term/' . $term[4]['tid']) . ' ';
?>

 <?php print trim($str, '-&nbsp;'); ?>
<?php endif ?>
