Count records from a mysql table

I have this carousel that I want to make dynamic. To operate, the carousel must begin with a class 

 <div class="item active">

and must stay out of the while loop. After the fourth record extract, the class must become simply

 <div class="item">

In summary:

   0 to 4 ->  <div class="item active"> 
   5 to 8 --><div class="item">
   9 to 12 --> <div class="item"> ....so on

How do I count the records extracted? Thanks

 <?php
   $banner = "SELECT * FROM tbl_banner";
        $result_b = dbQuery($banner); 
        // here --> <div class="item active">  or <div class="item">  
          while($row_b = dbFetchAssoc($result_b)) {
            extract($row_b);
?>               
            <div class="col-md-3">
                 <div class="w-box inverse">
                    <div class="figure">
                       <img alt="" src="banner/<?php echo $img; ?>" class="img-responsive">
                         <div class="figcaption bg-2"></div>
                          <div class="figcaption-btn">
                             <a href="banner/<?php echo $img; ?>" class="btn btn-xs btn-one theater"><i class="fa fa-plus-circle"></i> Zoom</a>
                              <a href="#" class="btn btn-xs btn-one"><i class="fa fa-link"></i> View</a>
                     </div>
               </div>
                  <div class="row">
                     <div class="col-xs-9">
                       <h2><?php echo $img_title; ?></h2>
                         <small><?php echo $img_desc; ?></small>
                             </div>

                                    </div>
                                </div>
                            </div>

  <?php                               
    }
   ?>

I don't understand.... I would like a result like this, explained in this way:

$query ="SELECT .....
 <div class="row">
  <div class="item active">
 while { 
  <div1>...</div>
  <div2>...</div>
  <div3>...</div>
  <div4>...</div>
} //end while

</div>
</div>

<div class="row">
<div class="item">

while {
<div4>...</div>
<div6>...</div>
<div7>...</div>
<div8>...</div> 

} //end while

etc etc

SELECT COUNT(*) AS cnt FROM tbl_banner

OR

count( $res ); # in php

Also see: Which is fastest? SELECT SQL_CALC_FOUND_ROWS FROM `table`, or SELECT COUNT(*)

You can use num_rows to see how many rows were returned. Unfortunately from your question I can't tell whether you're using MySQL, MySQLi or PDO as it seems you pass all your queries into a class.

For MySQLi use the following:

$num = $result_b->num_rows;
