How can JSON data be formatted as an array for use in Highchart in PHP?

To format JSON data as an array for use in Highcharts in PHP, you can create an array in PHP and encode it as JSON using the json_encode function. This array should follow the specific format required by Highcharts, typically with keys like 'name' and 'data' for each data series. Once the JSON data is formatted correctly, you can pass it to Highcharts for visualization. 

```php
$data = array(
    array('name' => 'Series 1', 'data' => array(1, 2, 3, 4, 5)),
    array('name' => 'Series 2', 'data' => array(2, 3, 4, 5, 6)),
    array('name' => 'Series 3', 'data' => array(3, 4, 5, 6, 7))
);

$json_data = json_encode($data);
```
In this code snippet, we create an array $data with three data series, each containing an array of data points. We then use json_encode to convert this array into a JSON string that can be used with Highcharts.
