Zend_Acl

Zend_Acl is a component in software development that manages permissions and access control. It helps developers define and organize who can view, edit, or perform specific actions within an application. By setting rules and roles, Zend_Acl ensures that users only access what they're authorized to, enhancing security and streamlining permission management. Think of it as a sophisticated gatekeeper that enforces access policies across different parts of a website or system.
