Question

Whenever there is a space in between the post it soows rn. This is how I read the insert data:

$content_of_post_original = mysql_real_escape_string($_POST['post_content']);
$content_of_post = stripslashes($content_of_post_original);

And then printed:

echo $show['post_content']

Answer 1

\r\n means a new line. Your strip slashes is removing this and just echoing rn instead of a new line.
