"+" . addRotation('\\2') . "+" . addRotation('\\3') ."\" rel=\"nofollow\" target=\"_blank\"", $output); echo $parsed; Expected result: ---------------- <html><head><head><body><a href="/folder/?e=rknzcyr@rknzcyr.com">this is a test</a></body></html> Actual result: -------------- <html><head><head><body><a href="/folder/?e=example@example.com">this is a test</a></body></html> ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=49699&edit=1
