What is CakePHP?

CakePHP is an open-source framework for the rapid development and maintenance of web applications built in PHP. It is based on the concept of MVC architecture, which helps to build PHP web applications easily and simply with less code. CakePHP also helps you to separate business logic from the data layer and presentation layer.

Why use CakePHP Framework?

Here are the prime benefits/pros of using the CakePHP framework:

  • CakePHP is by far one of the quickest web development platforms.
  • CakePHP allows developers to gain enhanced control over the database and SQL queries.
  • It helps users to rapidly develop robust web applications without losing their environment flexibility.
  • Support for PostgreSQL, SQLite, MySQL, and PEAR-DB for ADODB, a database abstraction library.
  • Facilitates search-engine-friendly URLs.
  • Provides features like input validation and sanitization tools which make the app secure.
  • Templating with familiar PHP syntax.

How to Install CakePHP

The recommended way to install CakePHP is with Composer, the PHP dependency manager. Once Composer is installed, run the command below to create a new project skeleton.

composer create-project --prefer-dist cakephp/app:~5.0 my_app

The command downloads CakePHP and its dependencies into a folder named my_app. You can then start the built-in server with bin/cake server and open http://localhost:8765 in your browser. Note that CakePHP 5 requires PHP 8.1 or later.

History of CakePHP

Now in this CakePHP tutorial, we will cover the history of the CakePHP framework:

Year Milestone
2005 CakePHP was developed by Michal Tatarynowicz on April 15, 2005.
2005 CakePHP published it under the MIT license and opened it to the community developers.

2006 Version 1.0 was released.
2011 Version 2 was released.
2014 Version 3 was released, a complete rewrite of earlier versions.
2016 Version 3.3 of CakePHP was released with many advanced features.
2019 Version 4.0 was released, modernizing the framework.
2023 CakePHP 5.0 was released, requiring PHP 8.1 or later. The current release in 2026 is CakePHP 5.3.x.

CakePHP- Folder Structure

Now in this CakePHP framework tutorial, we will learn about the CakePHP folder structure.

Below is a folder structure of CakePHP:

Folder Description
Tests This folder contains test cases for your application.
Tmp The tmp folder stores temporary data.
Vendor This folder is where CakePHP and other application dependencies are installed.
Webroot The webroot stores all the files you want to be publicly reachable.
Bin The bin folder holds the Cake console executables.
Logs It contains your log files, which depend on your log configuration.
Config The config folder stores the configuration files CakePHP uses.
Plugins This is where the plugins your application uses are stored.
Src It contains the code for your application, such as controllers, entities, and behaviors. Locale stores string files for internationalization, and Model contains your application’s tables, entities, and behaviors.

Configuration of CakePHP

CakePHP comes with a single configuration file by default. It also allows you to modify it according to your requirements. There is a folder called “config” given for this purpose.

Variable Name Description
Debug Allows you to change CakePHP debugging output.
App.namespace Helps you to find the app classes.
App.baseUrl Un-comment this keyword when you don’t want to use Apache’s mod_rewrite with CakePHP.
App.encoding Allows you to define what encoding your application uses.
App.base It is the base directory the app resides in. If false, this will be auto-detected.
App.fullBaseUrl Fully qualified domain name.
App.webroot It is the webroot directory.
App.wwwRoot The file path to the webroot.
App.jsBaseUrl Path to the public js directory.
App.paths Configure paths for non-class based resources.
App.cssBaseUrl It is the web path to the public css directory under webroot.
Security.salt It is a random string used in hashing.
Asset.timestamp This variable appends a timestamp when using the proper helpers.

Cake- PHP naming conventions

Cake follows the idea of convention over configuration. The naming convention allows you to organize the operation of the web application. In this method, more than one word in a name must be separated by “_” when naming the file, and camel case when naming the class.

The MVC parts must follow the syntax given below:

File Name Class Name Base Class Name Location
Model Singular form of the table name with a .php extension, ex: order.php The file name in camel case, ex: Order AppModel /app/models
Controller tablename_controller with a .php extension, ex: orders_controller.php The table name appended with Controller, ex: OrdersController AppController /app/controllers
View The action name in the controller with a .ctp extension, ex: add.ctp No classes; a view contains HTML tags and PHP. /app/views/controller name

Databases Configuration

CakePHP allows you to configure the database in the config/app.php file. It provides a default connection with provided parameters which you can modify per your choice.

Important parameters are given below:

Parameter Description
port (optional) The TCP port or Unix socket used to connect to the server.
Timezone Server timezone to set.
Schema It helps you to specify which schema you can use.
unix_socket Used by drivers to connect via Unix socket files.
ssl_key It is the file path to the SSL key file.
ssl_cert It is the file path to the SSL certificate file.
ssl_ca It is the file path to the SSL certificate authority.
Log This term helps you to perform query logging.
Init A list of queries which should be sent to the database server whenever the connection is created.
quoteIdentifiers Set to true if you want to use reserved words or special characters.

How does MVC work in CakePHP?

Now, we will learn how MVC works in CakePHP in this CakePHP framework tutorial.

It is a dynamic way to build the prime mechanism of a web application. The model, the view, and the controller are separate from each other.

MVC architecture in CakePHP
MVC architecture in CakePHP

CakePHP splits operations into three parts:

  • Models: Used for all database interactions.
  • Views: Used for all output and displays.
  • Controllers: Used to control the application flow.

Here are the steps to use the MVC architecture in CakePHP:

Step 1) The client or user interacts with the view.

Step 2) The view alerts the controller of the specific event.

Step 3) The controller sends a database request to the model and updates the model.

Step 4) The model alerts the view that it has changed.

Step 5) The view receives the model data and updates itself according to the received data.

Why use MVC?

  • CakePHP MVC helps you to separate business logic from presentation and data retrieval.
  • A site is divided into logical sections which you can govern with a specific controller.
  • When testing and debugging an application, any developer can locate and correct errors without having complete details of the code.

Disadvantages of using the CakePHP framework

  • The documentation support of CakePHP is not as comprehensive as it should be.
  • To use CakePHP, the developer needs to update the default routes for creating fancy URLs, which is more work compared to some other PHP frameworks.
  • CakePHP uses one-way routing compared to other frameworks.
  • Learning the PHP framework is not always easy for beginners.
  • One-way routing is another disadvantage when compared with frameworks such as Ruby on Rails.

FAQs

Yes, for maintaining existing CakePHP projects and for teams that value its convention-over-configuration approach. Laravel and Symfony have larger communities, but CakePHP 5 is actively maintained and remains a solid, productive framework.

Both are MVC PHP frameworks. Laravel has a larger ecosystem, expressive syntax, and Eloquent ORM. CakePHP emphasizes strict conventions and rapid scaffolding with less configuration. Laravel is more popular; CakePHP can be faster to start a conventional app.

CakePHP 5, the current major version, requires PHP 8.1 or later. Older CakePHP 4 supported PHP 7.4 and up, but it is nearing end of life, so new projects should target CakePHP 5 on a modern PHP release.

Yes. AI can generate the migration, entity, table, controller, and templates for a CRUD resource following CakePHP conventions, and explain the bake console commands. Review the validation rules and test each action.

Yes. AI can flag deprecated methods, updated namespaces, and signature changes, and suggest replacements step by step. Because migrations are large, upgrade incrementally and run the test suite after each change.
