How can form elements be transferred as arrays and processed server-side in PHP?

To transfer form elements as arrays and process them server-side in PHP, you can use array notation in the form field names. This allows you to group related form fields together and access them as arrays in PHP. For example, if you have multiple input fields for a set of data, you can name them like "data[]" in the form, which will be sent as an array to the server. 

<form method="post" action="process.php">
    <input type="text" name="data[]" />
    <input type="text" name="data[]" />
    <input type="text" name="data[]" />
    <input type="submit" value="Submit" />
</form>
```

```php
// process.php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $data = $_POST['data'];
    
    foreach ($data as $value) {
        // Process each value in the array
        echo $value . "<br>";
    }
}
