What is a good php code

I'm have a problem with using this code:

<?php
    for($i=0;$i<=10;$i++){
?>
        <p><?php echo $i ?></p>
<?php
    }
?>

and this code:

<?php
    for($i=0;$i<=10;$i++){
        echo'<p>'.$i.'</p>';
    }
?>

which is better php code when you need to use html tag inside your php code?
