When implementing a multi-lingual site in CodeIgniter, the Model adapts the data retrieval logic using ________.
- Config Files
- Helper Functions
- Language Files
- Routes
CodeIgniter supports multi-lingual sites by allowing the Model to adapt data retrieval logic using Language Files, making it easier to manage and organize language-specific content in the application.
When a developer encounters a complex query requirement that involves conditional aggregation, the most suitable Query Builder method to use is ________.
- aggregate()
- conditional()
- group_by()
- having()
In CodeIgniter's Query Builder, the having() method is used for conditional aggregation. It is applied after the group_by() clause and is suitable for handling complex queries that involve conditional aggregations.
How do you load a custom library in a CodeIgniter controller?
- $this->library->load('custom_library');
- $this->load->library('custom_library');
- $this->load_library('custom_library');
- $this->load_library('custom_library');
In a CodeIgniter controller, you can load a custom library using the syntax: $this->load->library('custom_library');. This initializes the library, making its functions and methods available within the controller.
Advanced MVC frameworks often implement ________ to manage dependencies among components efficiently.
- Dependency Injection
- Lazy Loading
- Method Overloading
- Polymorphism
Advanced MVC frameworks often implement Dependency Injection to manage dependencies among components efficiently. Dependency Injection involves providing a component with its dependencies rather than allowing it to create them. This promotes flexibility, testability, and easier maintenance by decoupling components and facilitating easier component substitution.
What is the role of the 'uri_segment' parameter in CodeIgniter's pagination configuration?
- Configuring the total number of pages in the pagination sequence.
- Defining the base URL for pagination links.
- Setting the number of items per page.
- Specifying the URI segment that contains the page number.
The 'uri_segment' parameter in CodeIgniter's pagination configuration is used to specify the URI segment that contains the page number. This helps the pagination library identify and extract the page number from the URI.
How does CodeIgniter support the development of HATEOAS (Hypertext As The Engine Of Application State) in RESTful APIs?
- CodeIgniter provides a built-in HATEOAS library that simplifies the creation of hypermedia links.
- CodeIgniter relies on manual coding for HATEOAS implementation.
- CodeIgniter uses a third-party library for HATEOAS support.
- HATEOAS is not directly supported in CodeIgniter.
CodeIgniter simplifies the creation of hypermedia links by providing a built-in HATEOAS library. HATEOAS is essential for guiding API clients through available actions, improving discoverability and navigation.
In CodeIgniter, how can developers regenerate session IDs to enhance security?
- Developers need to manually regenerate session IDs using the regenerate_id() method.
- Regenerating session IDs is not a common practice in CodeIgniter.
- Session IDs are regenerated only on explicit user logout.
- Session IDs in CodeIgniter are regenerated automatically for each request.
To enhance security in CodeIgniter, developers can manually regenerate session IDs using the regenerate_id() method. This ensures that even if a session is compromised, the attacker would have an outdated session ID. Regularly regenerating session IDs is a good practice to minimize the window of opportunity for session-related attacks, contributing to a more secure application.
What is the role of 'Profiling' in CodeIgniter when it comes to performance optimization?
- It automates code optimization
- It enhances database design
- It helps in debugging code issues
- It provides insights into the application's performance
'Profiling' in CodeIgniter plays a crucial role in performance optimization by providing insights into the application's performance. It helps developers identify bottlenecks, inefficient queries, and other areas that can be optimized to enhance the overall speed and efficiency of the application.
In CodeIgniter, how do you load a Model inside a Controller?
- $model = new ModelName();
- $this->load->model('ModelName');
- include('ModelName');
- require('ModelName.php');
To load a Model in CodeIgniter, you use the $this->load->model('ModelName'); syntax. This makes the Model available for use within the Controller.
How do CodeIgniter's database utilities assist in handling database versioning?
- Automatic schema detection and adjustment
- Code generation for database schema
- Enforcing foreign key constraints through the ORM
- Version control through migration files
CodeIgniter's database utilities provide version control through migration files. Migration files allow developers to modify the database schema and keep track of changes, making it easy to apply updates across different environments.
In a typical payment gateway integration, which component is responsible for handling customer payment details securely?
- Application interface
- Database server
- Payment gateway API
- Web server
The payment gateway API is responsible for securely handling customer payment details. It encrypts and transmits sensitive information, such as credit card numbers, to the payment gateway for processing while ensuring data integrity and confidentiality.
For load balancing, CodeIgniter allows the specification of multiple database servers in the ________ array.
- config
- connection
- database
- server
CodeIgniter allows the specification of multiple database servers in the database array. This feature is useful for load balancing and managing multiple database connections efficiently.
