<a href="http://sharefo.com/index.php/archives/50.html"><?php the_title();?></a>
This line is a mix of HTML and PHP code. In English, it can be described as:
"A hyperlink (anchor tag) that points to 'http://sharefo.com/index.php/archives/50.html', with the link text being dynamically generated by the PHP function 'the_title()' which typically outputs the title of a post or page in WordPress."
