Exemple d'utilisation: 

	// Calculate Result   
		if($search->search($tag) > $nbPerpage)
      	{     
     
        	$paginate = new paginate();
            
            // Paginate 
        	if(isset($_GET["page"]) && !empty($_GET["page"]))
      		{
           	$page = $_GET["page"];
     
     		}
     
     		$nbResult = $search->search($tag);

     		$oS->assign("total",$nbResult);
     
      		$paginate->generate($nbResult, $nbPerpage, $page); 
    
            
     		if (is_array($paginate->getPaginate()) ) 
     		{
       
           	    if($paginate->currentPage() > 1 )
            	{ 
       
                   	$oS->assign("preview",$paginate->currentPage()-1);
     
           		}     
     
           		$oS->assign("paginate",$paginate->getPaginate());
     
      			if($paginate->currentPage() < $paginate->nbPages())
           		{
 
                 	$oS->assign("next",$paginate->currentPage()+1);
     
           		}

     		}
     
       		$oS->assign("firstId",$paginate->firstId);
     
     		$lastentry = ($paginate->firstId+$nbPerpage)-$nbResult;
     
     		$oS->assign("lastentry",($paginate->firstId+$nbPerpage)-$lastentry);
         
            $firstId = $paginate->firstId;

Exemple d'utilisateur avec smarty : 

  <div id="paginate">
    {if $preview neq NULL}
         <a href="/search/{$preview}/?tag={$tag}">« Preview</a>
    {/if}
    {foreach from=$paginate key=id item=page}
         {if $page eq 1}
               
               <a href="/search/{$id}/?tag={$tag}">{$id}</a>
         
         {elseif $page eq 2}
         
               <span class="selectednow">{$id}</span>
         {elseif $page eq 3}
          ...      
         {/if}       
    {/foreach}
    {if $next neq NULL}
         <a href="/search/{$next}/?tag={$tag}">Next »</a>
    {/if}
  </div>   


Une bref explication :

la method $paginate->getPaginate() renvoi un tableau :

array(6) { [1]=>  int(2) [2]=>  int(1) [3]=>  int(1) [4]=>  int(1) [5]=>  int(1) [6]=>  int(3) } 


Et quand une clé [X]=>  int(1) >> Les autres Pages;
Et quand une clé [X]=>  int(2) >> Page actuel; 
Et quand une clé [X]=>  int(3) >> Afficher les trois points (...);
