CakePHP Files and Folder Structure

November 6th, 2008 admin
When you unpack Cake on your server you will find four folders – app, cake, tmp and vendors. The cake folder is where the core libraries for Cake lay and you generally won’t ever need to touch them unless you want to do some customization to Cake itself.


The app is where your application specific folders and files will go. The separation between the cake folder with the core libraries and the app folder make it possible for you to have many app folders sharing a single set of Cake libraries. This also makes it easy to update CakePHP: you just download the latest version of Cake and overwrite you current core libraries; No need to worry about overwriting something you wrote for your app.

The tmp directory is used for various Cake operations, such as baking (automatically creating new php files), caching, and logging.

You can use the vendors directory to keep third-party libraries in. You’ll learn more about vendors later.

The folders structure and their basic purposes:

— root (the root directory)

— — app (here’s where your application logic will go)

— — — config (application specific configurations)

— — — controllers (controllers go here)

— — — — components

— — — index.php

— — — models (models go here)

— — — plugins (third party apps – go here)

— — — views (view related files go here)

— — — — elements (small repeated layout items go here)

— — — — errors (error pages go here)

— — — — helpers (your home-based helpers go here)

— — — — layouts (page layouts go here)

— — — — pages (static content managed by PagesController go here)

— — — webroot (this directory as your webroot, and stick your public files in here)

— — — — css

— — — — files

— — — — img

— — — — js

— — cake (this is where the libraries are placed: Note: it’s best not to touch)

— — index.php

— — tmp (used for logs, baking, etc.)

— — vendors (stick your third party libraries here)

How to Installing CakePHP?

November 6th, 2008 admin

Step 1 : Getting the most recent stable version
To install Cake PHP you first need to download the latest stable version from the CakePHP website at www.cakephp.org, once at the website click on Downloads > Release.
Download link : http://cakephp.org/downloads/index/nightly/1.2.x.x

Step 2: Unpacking
Now that you’ve downloaded the most recent release, place that compressed package on your web server in the webroot. Now you need to unpack the CakePHP package. There are two ways to do this, using a development setup, which allows you to easily view many CakePHP applications under a single domain, or using the production setup, which allows for a single CakePHP application on the domain.

History of CakePHP

November 6th, 2008 admin

CakePHP started in 2005, when Ruby on Rails was gaining popularity. The community has since grown and spawned several sub-projects. CakePHP is not a port of Ruby on Rails to PHP, but appropriates many of its useful concepts.

The Mambo Foundation announced in 2007 that it would utilize the CakePHP framework for future versions of its widely used content management system, calling CakePHP a “solid choice and certainly one of the top frameworks available today.”
