I have this array

```
$data['key'] = array(11,5,7);
$data['value'] = array(78,54,96);

```

I have sorted it based on value. So now I have - 

$data['key'] = (5,11,7);
$data['value'] = (54,78,96);

How can i get the first set of key-value pair i.e. the one which has the min value.

I want the o/p as -

```
(5,54) 

```

can someone pls explain how this can be done?
