Put label that is printed in PHP inside a div

I want to show a record of my database. I used PHP to create, insert, and select. The problem is that when I show a record, it does echo within a div which is a Pop-up. The PHP code is within div Pop-up.

Example:

function select($dir, $base){
  ...
  echo "<br><label><b>$affiche[title]</b></label><br>"

}

 if(isset($_POST['insert']))//code is good here!
            {

               select($dir, $base); //affiche évènements 
            } 

And the html code:

<div id='abc' style="display:none"> </div>

    <div id="popup" style="display:none">

        <form method="POST" action="#">
           <input type=submit required  name='insert'>  
        </form>
    </div>
</body>

How do I show out of div ?
