Question

这是我的代码。我正在尝试将值accountId返回并分配给$ accountId，但我总是返回0。查询很好，它在PHP我的管理员返回我想要的值，但它不会在这里返回它。你知道为什么吗？

    $mysqli = new mysqli($SQLhost, $SQLusername, $SQLpassword, $SQLdatabase);

    $stmt = $mysqli->prepare("SELECT accountId FROM Account WHERE accountUsername=? AND accountPassword=?");
    $stmt->bind_param('ss', $username,$password);

    $stmt->execute();

    $stmt->bind_result($accountId);

    $_SESSION['accountId'] = $accountId;

工作代码：
$ mysqli = new mysqli（$ SQLhost，$ SQLusername，$ SQLpassword，$ SQLdatabase）;

    $stmt = $mysqli->prepare("SELECT accountId FROM Account WHERE accountUsername=? AND accountPassword=?");
    $stmt->bind_param('ss', $username,$password);

    $stmt->execute();

    $stmt->bind_result($accountID);

    $stmt -> fetch();

    $_SESSION['accountId'] = $accountID;

Bind_Result总是返回0
