To ensure backward compatibility, custom libraries in CodeIgniter may implement ________ checks for specific framework versions.
- CI_Version Checks
- Compatibility Checks
- PHP Version Checks
- Version Compatibility
CodeIgniter libraries often implement CI_Version checks to ensure compatibility with specific framework versions. This practice helps developers maintain backward compatibility and ensures that their libraries work seamlessly across different CodeIgniter releases.
To log all error types except for 'E_NOTICE', set the error_reporting level to ________.
- E_ALL
- E_NOTICE
- E_ERROR
- E_WARNING
In PHP, the error_reporting function is used to set the error reporting level. E_ALL includes all error types, so to log all error types except for 'E_NOTICE', the correct option is E_ALL.
In a recent security breach, an SQL injection attack was used to access sensitive data. The initial investigation should focus on the ________ used in the application.
- Authentication protocols
- Coding languages
- Database queries
- Encryption algorithms
The initial investigation should focus on the database queries used in the application. SQL injection attacks exploit vulnerabilities in the construction of database queries, allowing attackers to manipulate or retrieve sensitive data. Analyzing and securing the database queries is crucial in addressing and preventing such security breaches.
A developer is setting up a new CodeIgniter project on a shared hosting. The first step they should take for configuration is to adjust the ________.
- Application Language Configuration
- Database Configuration
- Server Environment Configuration
- URL Routing Configuration
When setting up a CodeIgniter project on shared hosting, adjusting the server environment configuration is crucial. This includes setting the base URL, index page, and other server-related settings in the config.php file to match the hosting environment.
In CodeIgniter, API rate limiting is often implemented using ________.
- Limit.php
- Rate.php
- Ratelimiter.php
- Throttling.php
CodeIgniter implements API rate limiting through the 'Limit.php' library, allowing developers to control the number of requests a user can make to the API over a specific period.
In CodeIgniter, what is the recommended approach to secure JSON and XML API endpoints?
- Applying API keys and securing with a token-based system
- Enabling CSRF protection and validating inputs
- Implementing OAuth for API authentication
- Using SSL/TLS for secure data transmission
The recommended approach in CodeIgniter to secure JSON and XML API endpoints is by applying API keys and implementing a token-based system. This helps in authenticating and authorizing requests, ensuring secure communication between clients and the API endpoints.
To view detailed benchmarking data in CodeIgniter, the ________ method must be enabled in the controller.
- _output()
- benchmark()
- display()
- render()
In CodeIgniter, the benchmark() method is used to view detailed benchmarking data. This function is commonly used to measure the time taken by specific parts of your code for performance analysis.
________ should be used in CodeIgniter to securely handle errors containing sensitive information.
- die()
- exit()
- log_message()
- show_error()
In CodeIgniter, the show_error() function should be used to securely handle errors containing sensitive information. It presents a user-friendly error message.
How does CodeIgniter's unit testing class help in improving the quality of the code?
- It automatically fixes common coding errors.
- It ensures proper syntax throughout the codebase.
- It facilitates the creation of automated tests for various parts of the application.
- It optimizes the code for better performance.
CodeIgniter's unit testing class allows developers to create automated tests, ensuring that different parts of the application work as intended. This helps catch bugs early in the development process, improving code quality. Automated tests also make it easier to refactor code without introducing new issues. This process contributes to the overall stability and reliability of the application.
To roll back a specific migration, the command ________ is used in CodeIgniter.
- migrate:rollback
- revert
- rollback
- undo
In CodeIgniter, the correct command to roll back a specific migration is migrate:rollback. This command is used to undo the last batch of migrations applied.
