OAuth tokens are used to:
- Authorize access to protected resources
- Define database tables
- Store session data
- Validate HTML forms
OAuth tokens are used to authorize access to protected resources. These tokens act as proof of authentication and are required for accessing the user's data or performing specific actions on their behalf.
To manually complete a transaction in CodeIgniter, the method ________ is used.
- commit()
- completeTransaction()
- endTransaction()
- finishTransaction()
In CodeIgniter, the commit() method is used to manually complete a transaction. This function is called when you want to make the changes permanent after a series of database actions.
Which of the following is a common practice to secure file uploads?
- Allowing any file type without restrictions
- Limiting the file types that can be uploaded
- Running file uploads with elevated server privileges
- Storing uploaded files in a public directory
A common practice to secure file uploads is to limit the types of files that can be uploaded. This prevents the upload of potentially harmful file types and adds an additional layer of security. Proper validation and server-side checks should be implemented to enforce this restriction.
When faced with a slow-running query, a CodeIgniter developer can utilize the ________ utility to diagnose and optimize performance.
- Caching Class
- Encryption Class
- Profiler Class
- Query Builder Class
The Profiler Class in CodeIgniter is used to benchmark and profile your application. When dealing with a slow-running query, a developer can enable the profiler to get detailed information about the query execution, helping diagnose and optimize performance issues.
In CodeIgniter, the ________ feature allows for the seamless transition of database structures across different environments.
- Database Transition
- Environment Transition
- Migration Transition
- Schema Transition
CodeIgniter's Schema Builder feature enables the smooth transition of database structures across different environments, making it easy to manage and evolve the database schema as needed.
In advanced MVC implementations, what is the role of a 'ViewModel'?
- Acts as an intermediary between the controller and the view
- Executes business logic
- Handles user authentication
- Manages database connections
In advanced MVC implementations, a 'ViewModel' acts as an intermediary between the controller and the view. It contains the data and business logic needed for the view, allowing the controller to focus on handling user input and updating the model. This separation enhances code maintainability and flexibility.
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 OAuth, what security considerations must be taken into account when implementing implicit grant flow?
- Allow any redirect URI to support flexibility.
- Do not validate the redirect URI, as it's handled by the implicit grant flow.
- Use a fixed redirect URI to simplify the implementation.
- Validate the redirect URI to prevent open redirect attacks.
Validating the redirect URI is crucial to prevent open redirect attacks, ensuring that the authorization response is sent to a legitimate endpoint. This helps in protecting against malicious redirections.
To improve code readability and reusability, a developer decides to move frequently used HTML structures to a Helper. This process is known as ________.
- code refactoring
- helperization
- templating
- view abstraction
The process of moving frequently used HTML structures to a Helper in CodeIgniter is known as helperization. This enhances code readability and promotes reusability by encapsulating common HTML patterns.
