remove \r\n from output

I know this question has been asked before but the answers are not the solution to my problem.

When i post a text with this code:

$info=html_entity_decode(mysql_real_escape_string($_POST['info']));

Like :

fdsa

fdsa

fasf

and when i posted this text with antered and spaces it looks like this

<?php echo $info;?>

fdsa\r\nfdsa\r\nfasf\r\n

i try this nl2br($info) but still not working.

What do I need to appear in the text in this way?

fdsa

fdsa

fasf

Replace the \r\n by <br>, the \n by <br>, then the\r by <br>:

$info = html_entity_decode($_POST['info']); 
$info = str_replace('\r\n' , '<br>', $info);
$info = str_replace('\n' , '<br>', $info);
$info = str_replace('\r' , '<br>', $info);

$info = html_entities($info);
echo $info;

You have to make multiples replacements since new lines can be represented differently according to the operating system (See this page for more details)

Finally, sanitize the value with html_entities before echoing it, preventing client side attacks.

EDIT : Removed the mysql_... function, not needed (the value isn't intended to be inserted in a MySQL database, not now at least).

Also, read Lashus advice bellow and apply it ;)
