Hello, that result is expected, read about the 'D' modifier in the
documentation: 
http://docs.php.net/manual/en/reference.pcre.pattern.modifiers.php


Thanks.

Description:
------------
strange bug, this code skip all characters expect the end \n (\r is
find).

This is the same when .*? is in subpattern.

Reproduce code:
---------------
$str = "test\ntest\r\n";

function v($s) {
echo '"'.$s.'"'."\n---\n";
}

echo v(preg_replace('#^.*$#s','', $str));
echo v(preg_replace('#^.*?$#s','', $str));
echo v(preg_replace('#^.*$#Us','', $str));

Expected result:
----------------
""

Actual result:
--------------
