Now here is the problem when I click on Edit button my all form data has been fetched from db but the formatting of textarea Text has been changed. It shows \\r\\r\\r\\n I use nl2br but its not working. I want to display my data in same formating.

You should change your php echo code as you dont need to include the !empty verification. If you do then you will have to create that before you echo the textbox. I suggest you change your code to this:
<textarea rows="20" cols="100" id="text" name="text" style="font-size:14px;" > <?php echo nl2br($text);?> </textarea><td>
You can also find some documentation of the nl2br here :

Upon inserting to the database, apply the nl2br - as you are likely to be presenting that data as text on a page more often than an textarea.
$mysql->real_escape_string(trim(nl2br($_POST['text'])))
Where $mysql is the mysqli database connection
Disclaimer As Bartdude mentioned, this is not especially good practice, since the information in the database should be as free from tags as possible - however, if this data is to be used in HTML pages only, then this solution should work.
Then when returning the data to a textarea, simply remove the <br> tags, the newline characters will be there anyway and should be interpreted by the browser correctly.
str_replace("<br>", " ", $row['text'])
