I have the loop below which iterates 4 times. Within this look is another which defines my group names. I would like to produce the output

```
Group 01
Group 02
Group 03
....
Group 15
Group 16

```

instead of what I currently get

```
Group 01
Group 02
Group 03
Group 04
Group 01
Group 02
Group 03
Group 04 
Group 01
Group 02
Group 03
Group 04
Group 01
Group 02
Group 03
Group 04

```

Code

```
foreach ($largegroups as $key => $users) { // loops 4 times
    for ($i = 1; $i <= 4; $i++) {
        $num = sprintf("%02d", $i);
        $groupname = 'Group ' . $num;
    }
}

```
