Using ZfcUser and BjyAuthorize to show or hide views - zend-framework2

Question

I have recently installed ZfcUser and BjyAuthorize and would like to use them to show or hide various parts of the layout.phtml file.
I understand that BjyAuthorize is a firewall of sorts and the flowchart from git hub suggests it should be possible to get current permission status and to use that to hide or show a particular section of code.
So for instance:
<ul>
<li>Admin Menu item</li>
<li>Affiliate menu item</li>
<li>Guest Menu item</li>
</ul>
If an admin user is logged in, he will view all three items, the affiliate will only see Affiliate and guest and the guest will only see guest.
How I was thinking of doing this was something like this:
<?php
//Get array of permissions for current user *not certain how to do this*
$permissionArray = $this->GetBjyPermissions($current->user);
?>
<ul>
<?php if in_array('admin',$permissionArray) {?>
<li>Admin Menu item</li>
<?php } ?>
<?php if in_array('affiliate',$permissionArray) {?>
<li>Affiliate Menu item</li>
<?php } ?>
<li>Guest Menu item</li>
</ul>
Essentially this will allow me to hide the sections of code a user is not allowed to use.
If it is not possible to get the permissions via Bjy or Zfc I guess my option would be to simply query the Database and build a permissions array from that directly.
Has anyone else had to do something like this? Is this approach a good approach or is there another way of achieving this?
Many thanks for any input.

You can use the BjyAuthorize's IsAllowed view Helper. It knows the current user's identity, so you just have to check the rule. It works like:
$isMenuAdmin = $this->isAllowed( 'menu', 'menu_admin' );
$isMenuAffiliate = $this->isAllowed( 'menu', 'menu_affiliate' );
$isMenuGuest = $this->isAllowed( 'menu', 'menu_guest' );
menu is a resource and menu_* a rule. You have to define them in the bjyauthorize.global.php. I'd do it this way:
(...)
'resource_providers' => array(
'BjyAuthorize\Provider\Resource\Config' => array(
'menu' => array(),
),
),
'rule_providers' => array(
'BjyAuthorize\Provider\Rule\Config' => array(
'allow' => array(
/*
[0] -> role
[1] -> resource
[2] -> rule
*/
array( array( 'admin' ), 'menu', array( 'menu_admin' ) ),
array( array( 'affiliate' ), 'menu', array( 'menu_affiliate' ) ),
array( array( 'guest' ), 'menu', array( 'menu_guest' ) ),
),
),
),
(...)
BTW, it seems that you're trying to build a menu. I recommend you to check this post about integrating Zend Navigation with BjyAutorize.
