$str = "we are escaping \r\n"; //we are escaping
?>

?>you might want to do a double stripslashes to completely remove 3 consecutive slashes
$stripped = 'this is a string with three\\\ slashes';
$stripped = stripslahses($stripped);
would output:
'this is a string with three\ slashes'
$stripped = 'this is a string with three\\\ slashes';
$stripped = stripslahses(stripslashes($stripped));
would output:
'this is a string with three slashes'
