How can the use of is_array and foreach be beneficial when working with form data in PHP?

When working with form data in PHP, it is important to check if the data received is an array before iterating over it. This can be done using the `is_array` function. Additionally, using a `foreach` loop to iterate over the form data allows for easy processing of each element in the array. 

if (is_array($_POST['form_data'])) {
    foreach ($_POST['form_data'] as $key => $value) {
        // Process each element in the form data array
    }
}
