CakePHP Request Cycle
The following illustration describes how a Request Lifecycle works −
A typical CakePHP request cycle starts with a user requesting a page or resource in your application. At a high level, each request goes through the following steps −
- The webserver rewrite rules direct the request to webroot/index.php.
- Your application’s autoloader and bootstrap files are executed.
- Any dispatch filters that are configured can handle the request, and optionally generate a response.
- The dispatcher selects the appropriate controller & action based on routing rules.
- The controller’s action is called and the controller interacts with the required Models and Components.
- The controller delegates response creation to the View to generate the output resulting from the model data.
- The view uses Helpers and Cells to generate the response body and headers.
- The response is sent back to the client.
