maybe it's should work with others filters :

var_dump(filter_var("", FILTER_DEFAULT, array('flags' => FILTER_FLAG_EMPTY_STRING_NULL)));
var_dump(filter_var("", FILTER_UNSAFE_RAW, array('flags' => FILTER_FLAG_EMPTY_STRING_NULL)));
var_dump(filter_var("", FILTER_SANITIZE_STRING, array('flags' => FILTER_FLAG_EMPTY_STRING_NULL)));
var_dump(filter_var("", FILTER_SANITIZE_STRIPPED, array('flags' => FILTER_FLAG_EMPTY_STRING_NULL)));
var_dump(filter_var("", FILTER_SANITIZE_ENCODED, array('flags' => FILTER_FLAG_EMPTY_STRING_NULL)));
var_dump(filter_var("", FILTER_SANITIZE_SPECIAL_CHARS, array('flags' => FILTER_FLAG_EMPTY_STRING_NULL)));
var_dump(filter_var("", FILTER_SANITIZE_FULL_SPECIAL_CHARS, array('flags' => FILTER_FLAG_EMPTY_STRING_NULL)));
var_dump(filter_var("", FILTER_SANITIZE_EMAIL, array('flags' => FILTER_FLAG_EMPTY_STRING_NULL)));
var_dump(filter_var("", FILTER_SANITIZE_URL, array('flags' => FILTER_FLAG_EMPTY_STRING_NULL)));
var_dump(filter_var("", FILTER_SANITIZE_NUMBER_INT, array('flags' => FILTER_FLAG_EMPTY_STRING_NULL)));
var_dump(filter_var("", FILTER_SANITIZE_NUMBER_FLOAT, array('flags' => FILTER_FLAG_EMPTY_STRING_NULL)));
var_dump(filter_var("", FILTER_SANITIZE_MAGIC_QUOTES, array('flags' => FILTER_FLAG_EMPTY_STRING_NULL)));
