PHP会话变量未定义

I have this session variable which i am trying to set to an access level when the users logs in with this:

 $accessquery = mysql_query("SELECT roleid FROM person WHERE email = '". $email ."'");
 $access = mysql_fetch_array($accessquery);

 $_SESSION['Access'] = $access;

However it says that 'Access' is undefined, what is the problem?

EDIT*

if (($_SESSION['Access']) == "2")

Error appears here

EDIT*

Session Start has been called.

我有这个会话变量，我试图在用户登录时设置为访问级别：< / p> 

  $ accessquery = mysql_query（“SELECT roleid FROM person WHERE email ='”。$ email。“'”）; 
 $ access = mysql_fetch_array（$ accessquery）; 
  
 $ _SESSION ['Access'] = $ access; 
   
 
 
然而它说'Access'未定义，有什么问题？ \  n 
 
 EDIT *  
 
 
  if（（$ _SESSION ['Access']）==“2”）
   \  n 
 
此处出现错误

已启动会话开始。

    Two possibilities here :

    1. Start the session by using session_start(); at the begining of page.

    2. use the following code:

      $accessquery = mysqli_query($conn, "SELECT roleid FROM person WHERE email = '". $email ."'", mysqli_store_result($conn));

$access = mysqli_fetch_row($accessquery);

$_SESSION['Access'] = $access[0];
