If you switch to multiline mode, by applying the m modifier, the D modifier is completely ignored. So $ will keep on matching before newlines as it does by default. However, you still could use \z.
PHP Code:
$str = "line1\nline2\n";
echo preg_match('/^line2$/m', $str); // TRUE
echo preg_match('/^line2$/mD', $str); // TRUE (D is ignored)
echo preg_match('/^line2\z/m', $str); // FALSE
