Answer 1

You could just use str_replace:

$str = str_replace(array('
', '
'), array('', ''), $str);

If you feel compelled to use regexp:

$str = preg_replace("~<(/)?pre>~", "<\\1code>", $str);

If you want to replace them separately:

$str = preg_replace("~
~", '', $str);
$str = preg_replace("~
~", '', $str);

You just need to escape that slash.
