I am trying to combine html and php to get a function.
<?php 
function display_text()
{
        $handle_text = '
        <div class="container">'.
        while($row=$stmt->fetch(PDO::FETCH_ASSOC))
        {
            extract($row); .'
                <div class="row">
                    <div class="col-2">
                    </div>
                    <div class="col-9">
                        '. echo $row['body']; .'
                    </div>
                </div> '.
        } .'
        </div>';
        return $handle_text ;
}
?>
However I get an error Parse error: syntax error, unexpected 'while' (T_WHILE) in C:\wamp64. 
How could I manage it? Thank you in advance.
