Proper error handling often involves logging errors to a(n) ________ for further analysis.
- ErrorLog
- LogFile
- LogRepository
- LoggingSystem
Proper error handling often involves logging errors to an error log for further analysis. This log can be a file, database, or another logging system, helping developers identify and address issues in a systematic manner.
In CodeIgniter, using ________ can help in passing data to views without explicitly sending it through the controller.
- $this->data
- $this->load->data
- $this->output->data
- $this->view->data
By using $this->data in CodeIgniter, you can pass data to views without explicitly sending it through the controller. This allows for cleaner code and separation of concerns. The data set in the controller can be accessed directly in the view, simplifying the process of passing information between the controller and the view.
To enable error logging in a production environment, the log threshold value is changed in the ________ file.
- config.php
- error.php
- index.php
- log.php
The log threshold for error logging in CodeIgniter is configured in the config.php file.
In a multi-environment setup, a developer uses CodeIgniter's ________ utility to manage different database configurations seamlessly.
- Database Configuration
- Database Forge Class
- Database Seeder Class
- Database Utilities
CodeIgniter's Database Configuration utility allows developers to manage different database configurations seamlessly in a multi-environment setup. It provides a way to define different database settings for development, testing, and production environments, ensuring smooth transitions between different setups without manual configuration changes.
How does CodeIgniter ensure data integrity during transactions?
- By employing foreign key constraints
- By implementing a two-phase commit protocol
- By performing periodic data audits
- By using database triggers
CodeIgniter ensures data integrity during transactions by employing foreign key constraints. Foreign key constraints establish a relationship between tables, ensuring that the values in a column (or columns) of one table match the values in another table's primary key. When a transaction involves multiple tables with foreign key relationships, CodeIgniter ensures that the foreign key constraints are satisfied, maintaining the consistency and integrity of the data across tables. Foreign key constraints prevent actions that would compromise the referential integrity of the database.
In CodeIgniter, how do you manage library versioning and compatibility with different CodeIgniter versions?
- Include version information in the library file header
- Maintain versioning information in the library configuration file
- Use a separate versioning file for each library
- Version numbers are not necessary for CodeIgniter libraries
It's good practice to include version information in the header of the library file. This ensures proper version tracking and compatibility checks.
In advanced database security, how does the principle of least privilege help in mitigating SQL injection risks?
- It encrypts the database
- It grants maximum access rights
- It grants the minimum necessary access rights
- It relies on strong passwords only
The principle of least privilege in advanced database security advocates granting the minimum necessary access rights to users or processes. By adhering to this principle, the risk of SQL injection is mitigated, as users and processes are only given the specific permissions required for their legitimate tasks, reducing the attack surface and potential impact of SQL injection attacks.
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.
