你做得很好。

我假设您需要知道SQL应该从数据库中获取用户数据。

<?php
session_start(); 
include("header.php"); 
include("conection.php");

//echo "lec name".$_SESSION["lecname"];

 if(isset($_SESSION["userid"]))
{
    $user_id = $_SESSION["userid"];

    $con=mysqli_connect("example.com","username","password","database_name");

    if (mysqli_connect_errno()){
      echo "Failed to connect to MySQL: " . mysqli_connect_error();
      }

    $result = mysqli_query($con,"SELECT banned FROM Lectures where user_id = ".$user_id);

    while($row = mysqli_fetch_array($result)){
        $banned= $row['banned'];
    }

    mysqli_close($con);

    if($banned == "1"){
        header("Location:lectureaccount.php");
    }
    else{   
        header("Location:banned.php");
    }
}

?>
<?php
//if(isset($_SESSION["userid"]))
{
    $lec_id = $_SESSION["userid"];
