What is the best practice for sending an array in an email using PHP?

When sending an array in an email using PHP, it is best practice to serialize the array before including it in the email body. This ensures that the array data is properly formatted and can be easily reconstructed on the receiving end. To serialize an array, you can use the `serialize()` function in PHP. 

// Sample array to be sent in an email
$array = array('item1', 'item2', 'item3');

// Serialize the array
$serialized_array = serialize($array);

// Include the serialized array in the email body
$email_body = "Here is the serialized array: $serialized_array";

// Send email with PHP's mail function
mail('recipient@example.com', 'Array Data', $email_body);
