How does CodeIgniter support RESTful controller methods?
- By configuring routes to handle RESTful requests
- By extending the REST_Controller class
- By using special annotations in the controller methods
- CodeIgniter does not support RESTful controller methods
CodeIgniter supports RESTful controller methods by extending the REST_Controller class. This class provides functionality to handle HTTP methods like GET, POST, PUT, and DELETE in a RESTful manner. It streamlines the process of building RESTful APIs in CodeIgniter.
Custom libraries in CodeIgniter are typically loaded using the ________ function in the controller.
- $this->library('library_name');
- $this->load->custom('library_name');
- $this->load->library('library_name');
- $this->load_library('library_name');
In CodeIgniter, libraries are loaded using the $this->load->library('library_name'); function in the controller. The correct syntax ensures that the library is loaded and ready for use in the controller.
During a security audit, a tester inputs 'OR '1'='1' into a login form to test for SQL injection. This test primarily targets the _________ of the application.
- Authentication mechanism
- Authorization logic
- Input validation
- Session management
This test primarily targets the input validation of the application. The provided input attempts to manipulate the SQL query by injecting a condition that is always true ('1'='1'). Proper input validation helps prevent SQL injection attacks by validating and sanitizing user inputs before processing them in SQL queries.
In a scenario where a CodeIgniter application is experiencing frequent SQL injection attempts, the developer should prioritize securing the ________.
- Controller Logic
- Database Queries
- Session Management
- User Authentication
In the scenario of frequent SQL injection attempts, securing the database queries is crucial. Developers should use parameterized queries or prepared statements to prevent SQL injection attacks. This involves validating and sanitizing user inputs before constructing and executing database queries, thereby mitigating the risk of unauthorized database access.
What is a 'custom exception' and when should it be used?
- A user-defined exception created to handle specific error conditions
- An exception that is never used in practice
- An exception that occurs only in custom-built applications
- An exception thrown by the programming language itself
A 'custom exception' is an exception defined by the programmer to handle specific error conditions in their code. It should be used when there are unique error scenarios that require special handling beyond the standard exceptions provided by the language.
In CodeIgniter, the logging level that includes error messages, debug messages, and informational messages is known as ________.
- ALL
- DEBUG
- ERROR
- INFO
The logging level ALL in CodeIgniter includes error messages, debug messages, and informational messages, providing a comprehensive view of the application's log.
In complex applications, ________ can be used to automatically run unit tests in different environments.
- CodeIgniter CLI
- Composer
- Continuous Integration
- Deployment Script
In complex applications, Continuous Integration (CI) is used to automatically run unit tests in different environments. CI systems like Jenkins or Travis CI integrate seamlessly with CodeIgniter, automatically triggering unit tests upon code changes. This ensures consistent code quality and identifies issues early in the development cycle.
Which feature of CodeIgniter simplifies the handling of complex XML structures?
- XML Configuration Files
- XML Data Models
- XML Helper Functions
- XML Parser Class
CodeIgniter simplifies the handling of complex XML structures through its XML Parser Class. This class allows developers to easily parse and manipulate XML data within their applications, providing a convenient way to work with XML content.
In the Active Record Class, what method is used to update an existing record in the database?
- modify()
- set()
- update()
- update_record()
In the Active Record Class of CodeIgniter, the update() method is used to update an existing record in the database. This method allows you to set new values for the fields of a record based on certain conditions. It simplifies the process of updating records by abstracting the underlying SQL queries and providing a more convenient and readable way to perform database updates.
When optimizing a CodeIgniter application for performance, a developer decides to replace a native library with a more efficient third-party library. The key factor to consider in this scenario is __________.
- Compatibility and support for future CodeIgniter versions
- Cost of the third-party library
- Licensing restrictions of the third-party library
- The ease of integration with CodeIgniter
When replacing a native library with a third-party one for performance optimization, compatibility with future CodeIgniter versions is crucial. This ensures that the application remains maintainable and can benefit from future updates without major disruptions.
