To set custom routing rules for a controller, one must edit the ________ file.
- application/config/custom_routes.php
- application/config/routes.php
- config/routes.php
- routes.php
To set custom routing rules for a controller in CodeIgniter, you need to edit the application/config/routes.php file. This file contains the routing rules for the entire application, allowing you to define custom routes for controllers and methods.
To view benchmark results in CodeIgniter, use the ______ method of the Output class.
- benchmark_output()
- display_benchmark()
- show_benchmarks()
- view_benchmarks()
In CodeIgniter, the show_benchmarks() method of the Output class is used to display benchmark results. This method provides information about the performance of your application, such as the time it took to load, the amount of memory used, and other benchmarking details.
In MVC, ________ is/are responsible for sending back the user response or output.

To enhance the default behavior of the CodeIgniter framework, a developer decides to use hooks. The implementation of these hooks should be placed in the ________ directory.
- application/config/hooks
- application/hooks
- system/config/hooks
- system/hooks
CodeIgniter hooks are stored in the application/hooks directory. This allows developers to extend or modify the behavior of the framework at specific points during the execution of the application.
While setting up an automated email notification system, a developer encounters issues with email deliverability. The first component to check would be ________.
- SMTP Server
- Email Template
- DNS Records
- Spam Filters
The correct option is "DNS Records." DNS records, specifically the SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) records, play a crucial role in email deliverability. Incorrect DNS configurations can lead to emails being marked as spam.
The ________ directory is crucial for managing different cache types in a CodeIgniter application.
- cache
- controllers
- helpers
- views
The 'cache' directory in CodeIgniter is essential for managing various cache types. Caching improves application performance by storing temporary data that can be quickly retrieved, reducing the need for time-consuming operations. Developers can configure and manage caching through this directory.
A developer creates a custom logging library in CodeIgniter for enhanced application monitoring. The appropriate method to integrate this library into the application's workflow is ________.
- Extend the CI_Log class
- Manually include the library in controllers
- Register the library in the autoload.php file
- Use autoload configuration
To integrate a custom library in CodeIgniter, developers should extend the CI_Log class. This ensures that the custom library functions as part of the core logging functionality, allowing for enhanced application monitoring. Autoload configuration is used for loading libraries, but extending the CI_Log class is the appropriate method for custom logging functionality.
When implementing pagination in an e-commerce site with filters, the developer must ensure that selected filters persist across different pages. This is typically achieved by ________.
- Embedding filter selections in the URL as query parameters
- Reloading filters on each page using AJAX
- Storing filter selections in session variables
- Using cookies to store filter selections
To ensure selected filters persist across pages, it's common to embed filter selections in the URL as query parameters. This allows the server to reconstruct the filter state on each request, ensuring a consistent user experience across paginated results.
How does xDebug integrate with CodeIgniter for advanced debugging?
- Automatic integration through Composer
- Direct integration in CodeIgniter config
- Manual configuration in php.ini
- xDebug doesn't integrate with CodeIgniter
xDebug integration with CodeIgniter involves manual configuration in the php.ini file. Developers need to enable xDebug, set breakpoints, and configure their IDE for a seamless debugging experience. Composer can also streamline the process.
