Question

我想通过其启动会话的代码如下：

$user = mysqli_fetch_array($run);
$run1 = mysqli_query($conn,"select * from users where email='$email' AND school_id='$school_id'"); 
$users = array();
while($user_r = mysqli_fetch_array($run1))
{
    $users[] = array("subject_id" => $user_r['subject_id'],"class_id" => $user_r['class_id']);
    $_SESSION['sub_cls']=$users;
}

但是我无法启动会话并且它不会返回任何值。我应该如何开始会议？

Answer 1

<?php 
session_start();
$user = mysqli_fetch_array($run);
$run1 = mysqli_query($conn,"select * from users where email='$email' AND school_id='$school_id'"); 
$users = array();
while($user_r = mysqli_fetch_array($run1))
{
    $users[] = array( "subject_id" => $user_r['subject_id'], "class_id" => $user_r['class_id'] );

}
  // create session, here we stored session in sub_cls variable 
   $_SESSION['sub_cls'] = $users;

读取read_session.php中的会话值

<?php 
    session_start();
    echo $_SESSION['sub_cls']['subject_id'];
    echo $_SESSION['sub_cls']['class_id'];
?>

如何将数组放入SESSION和Start Session
