How can the array retrieved from the database be properly passed to another PHP script for graph creation?

To pass an array retrieved from a database to another PHP script for graph creation, you can serialize the array using `json_encode()` before passing it as a URL parameter or in the request body. In the receiving script, you can then deserialize the JSON string back into an array using `json_decode()` to access the data.

// Retrieving data from the database
$data = // Retrieve data from the database here

// Serialize the array to JSON
$jsonData = json_encode($data);

// Pass the serialized array to the next PHP script
header("Location: graph_creation.php?data=" . urlencode($jsonData));
exit;
```

In the `graph_creation.php` script, you can then retrieve the passed data and decode it back into an array:

```php
// Retrieve the serialized array from the URL parameter
$jsonData = urldecode($_GET['data']);

// Decode the JSON string back into an array
$data = json_decode($jsonData, true);

// Now you can use the $data array for graph creation
