This component allows to manage ACL lists. An access control list (ACL) is a list of permissions attached to an object. An ACL specifies which users or system processes are granted access to objects, as well as what operations are allowed on given objects.
<?php
$acl = new Phalcon\Acl\Adapter\Memory();
//Default action is deny access
$acl->setDefaultAction(Phalcon\Acl::DENY);
//Create some roles
$roleAdmins = new Phalcon\Acl\Role('Administrators', 'Super-User role');
$roleGuests = new Phalcon\Acl\Role('Guests');
//Add "Guests" role to acl
$acl->addRole($roleGuests);
//Add "Designers" role to acl
$acl->addRole('Designers');
//Define the "Customers" resource
$customersResource = new Phalcon\Acl\Resource('Customers', 'Customers management');
//Add "customers" resource with a couple of operations
$acl->addResource($customersResource, 'search');
$acl->addResource($customersResource, array('create', 'update'));
//Set access level for roles into resources
$acl->allow('Guests', 'Customers', 'search');
$acl->allow('Guests', 'Customers', 'create');
$acl->deny('Guests', 'Customers', 'update');
//Check whether role has access to the operations
$acl->isAllowed('Guests', 'Customers', 'edit'); //Returns 0
$acl->isAllowed('Guests', 'Customers', 'search'); //Returns 1
$acl->isAllowed('Guests', 'Customers', 'create'); //Returns 1
