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.
Which HTML attribute is crucial for preventing XSS in user-generated content?
- href
- htmlspecialchars
- rel
- src
The htmlspecialchars function in PHP is crucial for preventing XSS in user-generated content. It converts special characters to HTML entities, preventing the browser from interpreting them as code. This helps to neutralize potential XSS attacks.
How can a controller in CodeIgniter pass data to a view?
- Using $this->data('key', 'value')
- Using $this->load->set('key', 'value')
- Using $this->load->view('view_name', $data)
- Using $this->view->set('key', 'value')
In CodeIgniter, data can be passed to a view by using the $this->load->view('view_name', $data) method, where 'view_name' is the name of the view file, and $data is an associative array containing the data to be passed.
In CodeIgniter, the naming convention for custom library files is ________.
- Customlibrary.php
- Library.php
- Library_custom.php
- My_library.php
The naming convention for custom library files in CodeIgniter is to use the format 'My_library.php' where 'My' is a user-defined prefix, and 'library' is the name of the library. This convention helps maintain consistency and avoid naming conflicts.
In CodeIgniter, handling different API versions is typically achieved through ________.
- Dependency Injection
- Middleware
- Routing
- Versioning
Handling different API versions in CodeIgniter is commonly achieved through versioning. This involves incorporating the API version into the URI or request headers, allowing developers to make changes to the API without affecting existing clients.
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.
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.
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.
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.
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.
