Get status unserialize error

I get status in interval from worker. At file Worker.php in method formatStatusData have code

```
$info = \file($statistics_file, \FILE_IGNORE_NEW_LINES);
if (!$info) {
return '';
}
$status_str = '';
$current_total_request = array();
$worker_info = \unserialize($info[0]);
\ksort($worker_info, SORT_NUMERIC);
```

But some time situation like this

array of $info is:

```
Log file
(
[0] => --------------------------------------------------------------------- WORKERMAN CONNECTION STATUS --------------------------------------------------------------------------------
[1] => PID Worker CID Trans Protocol ipv4 ipv6 Recv-Q Send-Q Bytes-R Bytes-W Status Local Address Foreign Address
[2] => 20788 6.01M websocket://0.0.0.0:8090 none 2 0 3 219

)
```

And i get error :

```
