Question on tab wrapping

So apparently I'm supposed to know how to use the php snippet to wrap my tabs, but I have no idea what you mean.

Here's my theme's code:

<div id="border" class="clearfix">
		    	  
		    	  <div id="main">

   		  	  		<div id="content" class="clearfix">
   			        	<div id="content-area" class="center column">

   						    <?php if (!empty($secondary_links) && empty($sidebar_left) && empty($sidebar_right)): ?>
   									<div class="block secondary">
   					    		    <?php echo theme('links', $secondary_links, array('class' => 'links secondary-links')); ?>
   								   		<div class="clear-block"></div>
   									</div>
   						    <?php endif; ?>

   				        	<?php echo $breadcrumb; ?>

   				        	<?php echo $messages; ?>				

   				  		  	<?php if ($content_top): ?>
   										<div id="content-top"><?php echo $content_top; ?></div>
   									<?php endif; ?>
   									
   				        	<?php if ($title): ?>
   				        	  <h1 class="title"><?php echo $title; ?></h1>
   				        	<?php endif; ?>
   				        	   				        	  
     				        <?php if ($tabs): ?>
     				          <?php echo $tabs; ?>
     				        <?php endif; ?>
     				        
     				        <?php if ((arg(1) == 'add') && (arg(0) == 'node')): ?>
     									<?php echo '<p class="form-info">' . t('Fields marked with a red star (<span title="This field is required." class="form-required">*</span>) are mandatory' . '</p>')?>
     								<?php endif; ?>
                    
     				        <?php echo $help; ?>
     					  		<?php if ($mission): ?>
     									<div id="mission"><?php echo $mission; ?></div>
     								<?php endif; ?>
                    
     				        <?php echo $content; ?>
                    
   		  	  		  	<?php if ($content_bottom): ?>
   										<div id="content-bottom"><?php echo $content_bottom; ?></div>
   									<?php endif; ?>

   							  	<?php echo $feed_icons; ?>

   			        	</div><!-- /content-area -->

   							</div> <!-- /content -->

How do I include your snippet?

Thank you and I apologize for the seemingly stupid question.
