method _bulk_reply is not returning the correct data

[DaLt0n]

Redis protocol sends a "CRLF" when it returns a string with zero length ($0), but when it returns a string "-1" ($-1) length it does not have a "CRLF". Solution is to remove "CRLF" when its a zero length string.

-- CIRedis::_bulk_reply --
remove: if ($value_length <= 0) return NULL;
add: if ($value_length <= 0) {
add: if ($value_length == 0) {
add: fgets($this->_connection);
add: }
add: return NULL;
add: }

Please submit a PR for this, since you have a fix already figured out.

Tried that. and now I'm getting null response..

    if ($value_length <= 0){
        if ($value_length == 0){
        fgets($this->_connection, $value_length + 1);
        }
        return NULL;
    }
