How does using 'Query Binding' in CodeIgniter help in performance optimization?
- Enhances server security
- Improves code readability
- Increases database connectivity
- Reduces the risk of SQL injection
'Query Binding' in CodeIgniter helps in performance optimization by reducing the risk of SQL injection. It allows the framework to properly escape and sanitize input, preventing malicious SQL injection attacks. This not only improves security but also ensures the integrity of the database interactions.
In the context of social media integration, what does API stand for?
- Advanced Programming Instruction
- Application Process Integration
- Application Programming Interface
- Automated Processing Interface
API (Application Programming Interface) is a set of rules that allows one software application to interact with another. In the context of social media integration, it enables communication between the web application and social media platforms.
To safeguard a CodeIgniter application from XSS attacks while allowing some HTML content, a developer should use ________.
- Cross-Origin Resource Sharing (CORS)
- Cross-Site Request Forgery (CSRF) Tokens
- Input Validation
- Output Escaping
To safeguard against XSS attacks while allowing some HTML content, a developer should use output escaping. This technique ensures that any user-supplied data displayed in the application is properly encoded, preventing malicious scripts from being executed. Output escaping is a defensive coding practice to enhance security.
In CodeIgniter, which function is used to load multiple Helpers at once?
- load with an array parameter
- load_helpers()
- load_helpers_array()
- load_multiple()
In CodeIgniter, the load function with an array parameter is used to load multiple Helpers at once. You can pass an array of Helper names, and CodeIgniter will load all of them, making it convenient when you need to use multiple Helpers in a controller or model.
For complex data passing in CodeIgniter, the ________ pattern can be utilized to separate logic from presentation.
- Adapter
- MVC
- Observer
- Singleton
In CodeIgniter, the MVC (Model-View-Controller) pattern is commonly used. The View handles the presentation logic, the Model manages the data and business logic, and the Controller acts as an intermediary, handling user input and managing the flow of data between the Model and the View. This separation helps in creating modular and maintainable code.
To prevent Cross-Site Scripting attacks, CodeIgniter provides a security filter known as ________.
- csrf_protection
- form_validation
- sanitize_input
- xss_clean
CodeIgniter includes a security filter called xss_clean to sanitize input data and prevent Cross-Site Scripting (XSS) attacks. It helps remove potentially malicious code from user inputs, enhancing application security.
