Say I have a multi-dimensional array:

```php

$arr[0][0] = 'pic0.jpeg';
$arr[0][1] = 'screenshot of videogame';
$arr[0][2] = 108.2;

$arr[1][0] = 'image.jpeg';
$arr[1][1] = 'someones face';
$arr[1][2] = 35.6;

$arr[2][0] = 'flower.jpeg';
$arr[2][1] = 'floral arrangement';
$arr[2][2] = 99.6;

// .... and so on...... 

```

Is there a library function that could sort the rows (entry for an image) by the third column (a numerical rating) while keeping each row intact? So the sorted array would be…

```php

$arr[0][0] = 'image.jpeg';
$arr[0][1] = 'someones face';
$arr[0][2] = 35.6;

$arr[1][0] = 'flower.jpeg';
$arr[1][1] = 'floral arrangement';
$arr[1][2] = 99.6;

$arr[2][0] = 'pic0.jpeg';
$arr[2][1] = 'screenshot of videogame';
$arr[2][2] = 108.2;

// .... and so on...... 

```
