Rewriting a Foreach section of code

I have this section of code that is displaying all entries within this table. Wondering how I can rewrite it so that it still shows the name and value by choosing the ID of the name and value.

I have figured out that its this line that makes it show all of them but thats as far as my knowledge goes.

<?php foreach ($item->extra_fields as $extraField): ?>

Code (markup):

Full Section of code

      <?php if($params->get('itemExtraFields') && count($item->extra_fields)): ?>  
<b><?php echo JText::_('Additional Info'); ?></b>
      <ul class="moduleItemExtraFields">
        <?php foreach ($item->extra_fields as $extraField): ?>
				<li class="type<?php echo ucfirst($extraField->type); ?> group<?php echo $extraField->group; ?>">
					<span class="moduleItemExtraFieldsLabel"><?php echo $extraField->name; ?></span>
					<span class="moduleItemExtraFieldsValue"><?php echo $extraField->value; ?></span>
					<br class="clr" />		
				</li>
        <?php endforeach; ?>
      </ul>
      <?php endif; ?>

You may write a function namely function($id){ // do activities and return name and value array based on the id above}
and call the function at the place you need.
