How to make article inside PHP [on hold]

How to make article inside PHP [on hold]

I want to make some articles in a PHP while loop. My initial code is as
follows:
<? php while(have_posts()): the_post() ?>
<article class="pt-page pt-page-9 bg-image6" id="blog">
</article>
<?php endwhile; ?>
Actually what I want to do is this, but this code does not make article.
However, when I paste this article code outside of PHP so it develops
single article, I need n articles.
Help me please.
