// First, grab the form data. Some things to note:
// 1. PHP replaces the '.' in 'data.json' with an underscore.
// 2. Your fields names will appear in the JSON data in all lower-case,

// 3. We need to handle the case where PHP's 'magic_quotes_gpc' option
// is enabled and automatically escapes quotation marks.

// Note: look at form_data_as_string above if you want to extract
// all fields and you don't necessarily know what they are before hand.

// $_REQUEST['email_address'] is the 'email_address' query parameter.
// For example, using this curl invocation would send an email to
// "support@unbounce.com":
// curl http://my-domain.com/this-php-script.php?email_address=support@unbounce.com
