here i am checking for and getting part of the request, (the ids). i also print out the entire request:
if (isset($_REQUEST['ids'])){
    $amount = sizeof($_REQUEST['ids']);
    print_r($_REQUEST);
    echo "<br>$amount invitations Successfully Sent";
}
this is how the entire $_REQUEST prints out:
Array
(
    [mfs_typeahead_req_form_4cf74f96db3688507476560] => Start Typing a Name
    [ids] => Array
        (
            [0] => 510149460
        )
    [fbs_258181898823] => \"access_token=258181898823|2.q_qb_yoReO0_xc4H8PxKRQ__.3600.1291280400-100000664203700|LqtGr_OiJTASGmek61awxmxfvFk&expires=1291280400&secret=85eTEELZj8lkV82V_PwRSA__&session_key=2.q_qb_yoReO0_xc4H8PxKRQ__.3600.1291280400-100000664203700&sig=d4cc0e4c0992ea29c0adfd60dc27185b&uid=100000664203700\"
)
i need to parse the part at the end: &uid=100000664203700, specifically '100000664203700'
