PHP如何设置通过ldap获得的变量值？

Question

I'm checking whether the user is admin or not from ldap also i'm getting value from ldap

Part of code is,

foreach ($memberOf as $key => $value) {
    $membership = explode(",", $value);
    $member     = explode("=", $membership[0]);
    if (in_array($member[1], $adminGroups)) {
        $is_admin = TRUE;

    } elseif (in_array($member[1], $userGroups)) {
        $is_admin = FALSE;
    }

So my question, how i can use this $is_admin variable everywhere in my application so that I can hide some buttons depending on whether user is an admin or not etc?

Do I need to set this variable in session?

Answer 1

Use PHP's sessions!

Simply session_start() at the top of the files you wish to use sessions in...

assign a session key

$_SESSION['is_admin'] = true;

then check the key later in different parts of your application...

if($_SESSION['is_admin'] === true) { /* do stuff */ }

Couple that with a function or class, you can have yourself a nice and easy authentication library.

Edit :

I've had to use LDAP authentication a bit.. the last thing you want to do is hammer the LDAP server and get your account locked, this is why I suggested sessions. Authenticate once... once authenticated, just use the session from there on out until it expires... then the user simply logs in again.

There are a couple of options:

• Using an session if you want it to persist after a page reload/navigation
• Use a static member in a static class so you can reference it everywhere if do not want persistence
