Zend Framework ACL: Inherits Including

This post is more than 18 months old. Since technology changes too rapidly, this content may be out of date (but that's not always the case). Please remember to verify any technical or programming information with the current release.

So one of the things that really bothered me about the Zend ACL implementation in 1.x was the inherits() method. It simply would test to see if the current role inherited the roles you were testing against. Well, what if the role WAS the tested role? Then it would fail. So, to fix that, in my own Application_Model_Acl implementation, I wrote inheritsIncluding().

Acl.php

<?php
class Application_Model_Acl extends Zend_Acl
{
  // snippy
  
  public function inheritsRoleIncluding($role, $inherit, $onlyParents = false)
  {
    $inherits = $this->inheritsRole($role, $inherit, $onlyParents);
    if (!$inherits) {
      $inherits = $role == $inherit;
    }
    return $inherits;
  }  
}

This simply calls the parent inheritsRole() method passing in all required parameters. If that is false, the last test is to see if the role actually is equal to the tested role. $inherits is false, but then is set to the calculation of whether the roles are equal or not.
