$body is the string that contains the body or text of your message.

For us we concatenate various items we are asking the visitor to complete:

ie,


$body = $body . "Phone: " . $_POST['phone'] . PHP_EOL;
$body = $body . "Term: " . $_POST['term'] . PHP_EOL;
$body = $body . "Inv: " . $_POST['investment'] . PHP_EOL;
$body = $body . "Hear: " . $_POST['hear'] . PHP_EOL;


Hope that helps.
