你好親愛的網絡朋友，今天我有一個問題，我不知道如何驗證 POST 中的 INPUT 數據，如果有人可以幫助我驗證這些數據，我將不勝感激，這就是代碼：include("GameEngine/Village.php");$unarray = array(1 => U1, U2, U3, U4, U5, U6, U11, U12, U13, U14, U15, U16, U21, U22, U23, U24, U25, U26, U31, U32, U33, U34, U35, U36, U41, U42, U43, U44, U45, U46, U0);if (isset($_GET['id']) && $_GET['id'] == 1) {    $res_qty = $_POST['resqty'];    $cost = $res_qty * 30;    $allres_qty = $res_qty * 100000;    $database->query("UPDATE " . TB_PREFIX . "users SET `gold` = `gold`- " . $cost . " WHERE id =" . $session->uid);    $database->query("UPDATE " . TB_PREFIX . "vdata SET `wood` = `wood` + " . $allres_qty . ", `clay` = `clay` + " . $allres_qty . ", `iron` = `iron` + " . $allres_qty . ", `crop` = `crop` + " . $allres_qty . " WHERE wref =" . $village->wid);    $_SESSION['info'] = $allres_qty . " Wood, Clay, Iron, Crop, added at the cost of " . $cost . " gold.";    header("Location:dorf1.php");}if (isset($_GET['id']) && $_GET['id'] == 2) {    $troop_type = $_POST['trooptype'];    $troop_qty = $_POST['troopqty'];    $cost = $troop_qty * 30;    $dt = array();    header("Location:dorf1.php");    for ($x = 1; $x < 11; $x++) {        $dt[$x] = 3333;        if ($x == $troop_type) $dt[$x] = floor($troop_qty * 3333);    }    $tribe = $database->getUserField($database->getVillageField($village->wid, "owner"), "tribe", 0);    if ($tribe == 1) {        $u = "";    } elseif ($tribe == 2) {        $u = "1";    } elseif ($tribe == 3) {        $u = "2";    } elseif ($tribe == 4) {        $u = "3";    } else {        $u = "4";    }    $database->modifyUnit(        $village->wid,        array($u . "1", $u . "2", $u . "3", $u . "4", $u . "5", $u . "6", $tribe . "0", "hero"),        array($dt[1], $dt[2], $dt[3], $dt[4], $dt[5], $dt[6], 0),        array(1, 1, 1, 1, 1, 1)    );}您好，我需要驗證的是我給我的用戶提供的部隊和資源的數量，這是在我的游戲中提供部隊的腳本，但我需要驗證部隊和資源，非常感謝！如果有人能幫助我，我將不勝感激！
