The framework also encourages you to write object oriented
code, which helps to ensure that maintenance of your application is simpler.
1.3 What is the Zend Framework?
The Zend Framework is a PHP library for building PHP web application. It provides a set of components to
enable you to build PHP applications more easily which will be easier to maintain and extend over the lifetime
of the application. That rather simple description doesn??™t tell the whole story though, so we will look at where
this framework came from and then have a brief look at what it actually contains
1.3.1 Where did it come from?
Frameworks have been around for years. The very first web framework I used in a real project was Fusebox
which was originally written for ColdFusion. Many other frameworks have come along since then, with the
next major highlight being Struts, written in Java. A number of PHP clones of Structs were written, but didn??™t
translate well to PHP. The biggest difference being that Java web applications run in a virtual machine that
runs continuously, so the startup time of the application is not a factor for every web request. PHP initializes
each request from a clean slate and so the large initiation required for Structs clones made them relatively slow
as a result.
