echo '
<div>
<a class="fragment" href="">
<div>';

In href I want to put value of some php variable i.e. $url How could be done?

is this correct way?

 <a class="fragment" href="<?php echo $url; ?>">

You concatenate the string by ending it and starting it again:

echo '
<div>
<a class="fragment" href="' . $url . '">
<div>';

Though I personally prefer to stop the PHP tags and start them again (if I have a lot of HTML) as my IDE won't syntax highlight the HTML as it's a string:

?>
    <div>
        <a class="fragment" href="<?php echo $url; ?>">link</a>
    </div>
<?php
