我的問(wèn)題是這兩個(gè)日期不會(huì)比較或至少不好。我嘗試了比較兩個(gè)日期的大部分答案。但沒(méi)有一個(gè)是成功的。我有權(quán)知道：else if ($_SESSION['org_id'] != "0" && $_SESSION['part_id'] == 0) {    require '../conn.php';    $sql = "SELECT `end_date` FROM `partner_subscriptions` WHERE `user_id` = '" . $dUsrId . "'";    $result1 = mysqli_query($conn, $sql );    $row = mysqli_fetch_array($result1);    if (date('Y-m-d') >= $row['end_date']) {        header('Location: ../../index');    } else {        header('Location: ../../partnersubscription');    }} 我嘗試過(guò)的一件事else if ($_SESSION['org_id'] != "0" && $_SESSION['part_id'] == 0) {    require '../conn.php';   // header('Location: ../../partnersubscription');    $sql = "SELECT `end_date` FROM `partner_subscriptions` WHERE `user_id` = '" . $dUsrId . "'";    $result1 = mysqli_query($conn, $sql);    $row = mysqli_fetch_array($result1);    $today = date("Y-m-d");    $expire = $row['end_date']; //from database    $today_time = strtotime($today);    $expire_time = strtotime($expire);    if ($expire_time > $today_time) {        header('Location: ../../index');    } else {        header('Location: ../../partnersubscription');    }} 我希望當(dāng)今天的日期小于行的日期時(shí)，它將進(jìn)入索引，否則將進(jìn)入合作伙伴訂閱。我的行end_date看起來(lái)像這樣“2019-06-06”并且是DATE
