A common method to sanitize user input and prevent XSS is using ________ encoding.
- Base64
- HTML
- URL
- XSS
HTML encoding helps prevent XSS attacks by converting special characters to their HTML entities, making them harmless.
What file extension is typically used for views in CodeIgniter?
- .ci
- .html
- .php
- .view
In CodeIgniter, views are typically saved with a .php extension. This allows the server to interpret and process the PHP code within the view file. The .html extension is not commonly used for CodeIgniter views.
During a high traffic period, a CodeIgniter application starts throwing database errors. The best practice to handle this scenario involves ________.
- Implementing Caching Mechanisms
- Implementing Database Connection Pooling
- Increasing the Database Query Timeout
- Using Shared Database Connections
During high traffic, using shared database connections in CodeIgniter is a recommended practice. It helps manage and reuse existing database connections, reducing the impact of opening and closing connections frequently during peak times.
In CodeIgniter 4, how does the Model's 'find' method enhance data retrieval flexibility?
- Allowing cross-database querying for distributed systems
- Enabling custom SQL queries for precise data retrieval
- Facilitating the retrieval of records based on primary key values
- Implementing automatic caching for improved performance
In CodeIgniter 4, the Model's 'find' method enhances data retrieval flexibility by facilitating the retrieval of records based on primary key values. This method simplifies the process of fetching a specific record from the database, providing a convenient and efficient way to retrieve data using the primary key as a reference.
What is the most efficient way to ensure that a third-party library is compatible with different versions of CodeIgniter?
- Regularly check for updates and patches from the library's developer
- Stick to the same version of CodeIgniter for all projects using the library
- Use version-agnostic functions and features provided by the library
- Write a wrapper class that adapts the library's code to different CodeIgniter versions
To ensure compatibility with different CodeIgniter versions, it's advisable to use version-agnostic functions and features provided by the third-party library. This approach allows the library to adapt to various CodeIgniter versions seamlessly, reducing the likelihood of issues when upgrading the framework. Additionally, regularly checking for updates and patches from the library's developer helps to stay informed about any changes or improvements related to CodeIgniter compatibility.
In a high-load CodeIgniter application, what technique is recommended for managing session data to optimize performance?
- Cookie-based sessions
- Database-driven sessions
- File-based sessions
- In-memory sessions
In high-load scenarios, managing sessions in a database can be more scalable and efficient, reducing the burden on the server and enhancing overall performance.
The ________ method in the Pagination class is used to create pagination links.
- build()
- create_links()
- generate()
- paginate()
The create_links() method in the Pagination class is used to generate HTML pagination links based on the configuration set. It creates the links you can use for navigating through different pages of the paginated results.
When integrating third-party APIs, a developer creates a Helper to manage API requests. This Helper should be stored in ________.
- controllers
- helpers
- models
- views
The Helper for managing API requests should be stored in the helpers directory. This helps in organizing and maintaining code related to external API integrations separately.
