Put this into your functions.php file:
function userfunc_get_post_views($postID) {
global $post_stats;
foreach ( $post_stats as $p ) {
if ( $p['post_id'] == $postID ) { ?>
<span class="stats-post-views">
<?php echo number_format_i18n( $p['views']) . ' views'; ?>
</span>
<?php }
}
}
and then into your single.php file where you want the views to be displayed:
<?php userfunc_get_post_views(get_the_ID()); ?>
This will wrap it in a div with the class of stats-post-views so you can style it.
