// Define dastination email list
$arrFriends = array('me@server.com','myfriend@server.com','another_friend@server.com');
// define expiration time (ex: 24hs)
$expiration = (time() + (24 * 3600));
$arrData = array(

"friends" => $arrFriends,
"message" => $string,
"date" => date("Y-d-m H:i:s"),
"expires" => $expiration,
