While retreiving the data from mysql through php(while loop) it retrieves one extra row which is NOT present in database. Why? : <?php
		               $con = mysqli_connect('mysql.host.in','user','pass','db');
		               $sql = $con->query("SELECT * FROM info");
		               while($row = $sql->fetch_array()){
		               $image = $row['image_path'];
               		   $caption = $row['caption'];
               		   $id = $row['id'];
               		?>
               		<div class="col-md-4">
	            		<div class="thumbnail">
	            			<img src=<?php echo $image;?>>
	            			<div class="caption text-center"><h3><?php echo $caption;?></h3></div>
	            			<button class="btn btn-default" onclick="modal(<?php  echo $id;?>)">View</button>
	            		</div>
            		</div><!-- Column END -->
            		<?php
            		 }
               		?>
