What is the primary purpose of unit testing in CodeIgniter?
- Analyzing database performance
- Detecting syntax errors
- Evaluating the user interface
- Verifying that individual units of code work as expected
Unit testing in CodeIgniter serves the purpose of verifying that individual units of code, such as functions or methods, work as expected. It ensures that each unit functions correctly in isolation before integrating them into the complete system, enhancing code reliability and maintainability.
To create a custom Helper in CodeIgniter, the file must be saved in the ________ directory.

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.
