- Environment Loader
- Environment Setup
- Environment Switching
The Environment Configuration feature in CodeIgniter enables the application to seamlessly run in different environments.
In CodeIgniter, how can you enable full query string support in URLs?
- Using the 'enable_query_strings' setting
- Modifying the .htaccess file
- Configuring the routes file
- Enabling the 'query_strings' option in config.php
In CodeIgniter, you can enable full query string support in URLs by setting the 'enable_query_strings' option to true in the 'config.php' file. This allows you to use traditional query string URLs instead of segment-based URLs.
To prevent script execution in uploaded files, it's important to set the correct ________ on the server.
- Encryption Key
- Execution Permission
- File Extension
- MIME Type
When uploading files, setting the correct MIME type on the server is crucial to prevent the execution of scripts. This ensures that only valid file types are accepted, enhancing security.
To enable RESTful API functionality in CodeIgniter, the ________ must be configured correctly.

In CodeIgniter, enabling RESTful API requires correct configuration in the 'config.php' file, specifying routes, and ensuring proper setup for the RESTful services.
When a user submits a form, the data is processed by a specific method in a controller. To securely handle this data, the controller should use ________.
- $this->form_validation->run()
- $this->input->get()
- $this->input->post()
- $this->security->xss_clean()
When handling form data in CodeIgniter, it's crucial to sanitize and secure the input. The $this->security->xss_clean() method helps in removing potentially harmful content, preventing cross-site scripting (XSS) attacks.
Which feature in CodeIgniter helps to filter input data to prevent SQL injection?
- Data Escaping
- Form Validation
- Input Validation
- Query Sanitization
CodeIgniter provides Query Sanitization as a mechanism to prevent SQL injection attacks by escaping and filtering input data.
What is the significance of using mock objects in CodeIgniter unit testing?
- Mock objects are only used in front-end testing.
- Mock objects are used for creating visual elements in unit tests.
- Mock objects are used to execute real database queries.
- Mock objects help simulate the behavior of real objects, making it easier to test individual components in isolation.
In CodeIgniter unit testing, mock objects are essential for isolating the code being tested. They simulate the behavior of real objects, allowing developers to focus on testing specific components without the need for the entire application to be running. This isolation is crucial for identifying and fixing bugs in individual units of code, providing more reliable and effective testing.
How can you pass multiple data items to a view in CodeIgniter?
- $this->load->data()
- $this->load->vars()
- $this->view->set()
- $this->view->set_data()
In CodeIgniter, the recommended method for passing multiple data items to a view is by using $this->load->vars(). This method accepts an associative array, making it easy to pass and organize multiple data items for the view.
When a new version of the API is deployed in CodeIgniter, maintaining backward compatibility is crucial for ________.
- API documentation
- Existing client applications
- SEO rankings
- User experience
Backward compatibility is essential for existing client applications that rely on the API. If backward compatibility is not maintained, existing clients may break, leading to a poor user experience. It also ensures a smooth transition for clients using older versions of the API, allowing them time to update and migrate to the new version without disruption.
The process of ________ is used by payment gateways to verify the funds and account details.
- Authentication
- Authorization
- Encryption
- Validation
In a payment gateway integration, the term "validation" refers to the process of confirming the legitimacy and accuracy of the provided information, ensuring the funds are available, and verifying the account details before completing a transaction. This step is crucial for security and financial integrity.
