Answer 1

Try htmlentities with ENT_QUOTES

Also, "\\n" is a one char. You have to replace it with your code. But also you must do back convert when saving.

Answer 2

http://www.php.net/manual/en/function.htmlentities.php

echo htmlentities($str, ENT_QUOTES);

might work but subject to mysql escaping, so a possibly better solution

http://www.php.net/manual/en/info.configuration.php#ini.magic-quotes-gpc

/.htaccess
php_value magic_quotes_gpc off

will prevent php auto-adding the slashes, you can then add them in sql with

mysql_real_escape_string()

in your sql statement

and removing them upon read [for textbox] with

stripslashes()

http://www.php.net/manual/en/function.stripslashes.php

to display in a DIV you'd have to htmlentities() as explained above
