Progress bar with cURL in PHP

[Ex1t]

I need progress bar in javascript for php cURL

 

This is my code

        $url = 'www.site.com'; 
        $list = array("ext.pdf", "ext_1.pdf", "ext_2.pdf", "ext_3.pdf", "ext_4.pdf"); 

        foreach($list as $lists) 
        { 
          $ch = curl_init(); 
          curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
          curl_setopt($ch, CURLOPT_HEADER, 1); 
          curl_setopt($ch, CURLOPT_URL, $url.$lists); 
          $result = curl_exec($ch); 
          curl_close($ch); 

          if (preg_match("/200 OK/", $result)){ 
              echo "<p>$url$lists</p>"; 
          } 
          else if (preg_match("/401 Unauthorized/", $result)) { 
              echo "<p>$url$lists</p>"; 
          }
