title: Accessing class variables
body: <p>It's the first time I use OOP with PHP 5.. so this is my problem..</p>
  
  <p>I have a file <code>disp.php</code> that contains a class named class disp (model in MVC)</p>
  
  <pre><code>&lt;?php
  class disp{
  public $n_pages;
  public $current_page;
  private $cmd2;
  
  /***************SQL command generator*******************/
  private function getCmd2($cmd1,$id,$first_entry,$perpage,$tri){
      $cmd2=str_replace('COUNT(*)','*',$cmd1);
      $cmd2=$cmd2.' ORDER BY '.$id.' '.$tri.' LIMIT '.$first_entry.','.$perpage;
      return $cmd2;
  }
  
  
  /********************Items display******************/
  function dispItems($cmd1,$id,$perpage,$tri){
    require('global/connection.inc.php');
    try{
  
       foreach($pdo-&gt;query($cmd1)as $r){
         $n_pages=ceil($r[0]/$perpage);
             if (isset ($_GET['pg'])){
            $current_page=intval($_GET['pg']);
                 if ($current_page&gt;$n_pages){
                      $current_page=$n_pages;
                 }
                 if ($current_page&lt;=0){
                     $current_page=1;
                 }
             }
             else{
             $current_page=1;
             $_GET['pg']=1;
             }
      }
  
  
      $i=1;
      $first_entry=($current_page-1)*$perpage;
  
      $objet=new disp();
       $cmd2=$objet-&gt;getCmd2($cmd1,$id,$first_entry,$perpage,$tri);
  
      $data=array();
      $i=0;
      foreach($pdo-&gt;query($cmd2) as $r){
      $data[$i]=$r;
      $i++;
      }
  
    return $data;
    }catch(PDOException $e){}
  }
  }
  </code></pre>
  
  <p>this is the file <code>news.php</code> (controller in MVC):</p>
  
  <pre><code>require MODELS_DIR.'disp.php';
  $objet=new disp();
  $news=$objet-&gt;dispItems('SELECT COUNT(*) FROM tbl_nouveautes','ID_EVENT',10,'DESC');
  
  $c_page=$objet-&gt;$current_page;
  $n_pages= $objet-&gt;$n_pages;
  
  
  require VIEWS_DIR.'disp-news.php';
  </code></pre>
  
  <p>in this code, I created an object (objet) of the type disp... I want to use the variables declared in the function <code>dispItems</code>, (<code>$n_pages</code> and <code>$current_page</code>) in the view (<code>disp-news.php</code>)</p>
  
  <p>so I think that the class variables are the same variables in the function <code>dispItems()</code>... but when trying to access them from the controller ...using object. it shows me a error :</p>
  
  <p>See:</p>
  
  <pre><code>Notice: Undefined variable: n_pages in C:\Program Files\EasyPHP-5.3.6.1\www\example\admin\global\news.php on line 14
  
  Fatal error: Cannot access empty property in C:\Program Files\EasyPHP-5.3.6.1\www\example\admin\global\news.php on line 14
  </code></pre>
  
  <p>Inspite of <code>$n_pages</code> and <code>$current_pages</code> being public in the class disp</p>
  
  <p>thank you in advance</p>
