What advanced technique is used in the Email Class for email encryption?
- AES Encryption
- MD5 Hashing
- RSA Encryption
- SSL Encryption
The Email Class in CodeIgniter utilizes SSL Encryption for securing email communication. SSL (Secure Sockets Layer) is a cryptographic protocol that provides a secure channel for data transmission. In the context of email, it ensures that the email content is encrypted during transmission, enhancing the security of sensitive information.
Controllers in CodeIgniter can extend the core class CI_Controller or ________ for more specialized functionality.
- Base_Controller
- Extended_Controller
- MY_Controller
- Special_Controller
In CodeIgniter, controllers can extend the core class CI_Controller for standard functionality. For more specialized functionality and to create a base controller with custom methods, you can create a new file named MY_Controller.php and extend CI_Controller.
What is the primary function of database helpers in CodeIgniter?
- Database helpers are used for loading database sessions.
- Database helpers assist in creating and managing database connections.
- Database helpers help with debugging and profiling database queries.
- Database helpers provide authentication mechanisms for database access.
CodeIgniter's database helpers primarily assist in creating and managing database connections. They simplify tasks related to database interaction in CodeIgniter, such as connecting to the database and executing queries.
The ________ method in CodeIgniter 4 Models allows for custom query building.
- build()
- custom()
- execute()
- query()
In CodeIgniter 4 Models, the query() method is used to execute custom SQL queries. This method allows for flexible and manual construction of queries when the standard query builder is not sufficient.
How does CodeIgniter's logging mechanism assist in identifying security issues?
- Captures and logs security-related events
- Logs only fatal errors
- Provides a detailed performance report
- Records user login information
CodeIgniter's logging mechanism helps identify security issues by capturing and logging security-related events, aiding in detecting and analyzing potential security threats.
In CodeIgniter, how is code coverage used in the context of unit testing?
- Code coverage calculates the time taken to execute unit tests.
- Code coverage determines the number of comments in the code.
- Code coverage is used to track the number of lines in the code.
- Code coverage measures the percentage of code that is executed during the unit tests.
Code coverage in CodeIgniter's unit testing context is a metric that indicates the percentage of code executed during the tests. It helps developers identify areas of the codebase that are not covered by tests, allowing them to create additional tests for better overall coverage. High code coverage is desirable as it indicates that most parts of the code have been tested, reducing the likelihood of undetected bugs in untested areas.
During the migration of a CodeIgniter application from development to production, it is crucial to modify the ________ settings to ensure proper functioning.
- Caching Configuration
- Database Connection
- Error Logging
- Session Configuration
When migrating a CodeIgniter application, adjusting the database connection settings is essential to ensure that the application connects to the correct database in the production environment. This involves updating the database hostname, username, password, and database name in the database.php configuration file.
Which CodeIgniter library is primarily used for handling sessions?
- Cookie Library
- Data Library
- Database Library
- Session Library
The Session Library in CodeIgniter is specifically designed for handling sessions. It provides functions to set, retrieve, and manage session data effectively. Integrating this library is a common practice for session management in CodeIgniter applications.
To use a third-party library in CodeIgniter, you must first __________ it in the application's configuration.
- Configure
- Initialize
- Integrate
- Load
In CodeIgniter, to use a third-party library, you need to configure it in the application's configuration. This involves specifying the necessary settings and parameters to make the library work seamlessly with your CodeIgniter application.
What is the role of CAPTCHA in form validation?
- Encrypts data transmission
- Ensures the form is submitted by a human
- Validates email addresses
- Verifies server connection
CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) plays a crucial role in form validation by ensuring that the form is submitted by a human and not an automated script or bot. This helps prevent spam submissions and enhances security.
When developing a mobile app with in-app purchases, the payment gateway integration should prioritize ________ for enhanced user experience.
- Blockchain Technology
- CAPTCHA Authentication
- Seamless Checkout Process
- Two-Step Verification
Prioritizing a seamless checkout process in the payment gateway integration for in-app purchases enhances the user experience, reducing friction and increasing the likelihood of successful transactions.
Which feature in CodeIgniter can be used to improve performance by caching entire web pages?
- Database Caching
- Fragment Caching
- Object Caching
- Page Caching
CodeIgniter provides a feature called 'Page Caching' to store entire web pages in the cache. This helps in improving performance by serving pre-rendered pages instead of re-rendering them on every request.
