Zend Framework - Concepts

Zend Framework is a collection of 60+ components. They are loosely connected with each other. They can be used as both stand-alone component as well as a group of components working as a single unit.

Zend Framework provides three most important components, which are −

• zend-servicemanager
• zend-eventmanager and
• zend-modulemanager.

They provide Zend components the ability to integrate with other components efficiently.

• Event Manager − It gives the ability to create event based programming. This helps to create, inject and manage new events.

• Service Manager − It gives the ability to consume any services (PHP classes) from anywhere with a little effort.

• Module Manager − Ability to convert a collection of PHP classes with similar functionality into a single unit called as a module. The newly created modules can be used, maintained and configured as a single unit.

We will cover these concepts in detail in the subsequent chapters.
