In a scenario where a user's access token is compromised, the OAuth implementation should allow ________ to mitigate the risk.
- Token Refresh
- Password Change
- Two-Factor Authentication
- Token Revocation
The correct option is "Token Revocation." If a user's access token is compromised, the OAuth implementation should support revoking or invalidating the token to prevent unauthorized access. This is a crucial security measure to mitigate the risk of unauthorized access.
To retrieve a specific session value in CodeIgniter, the syntax used is $this->session->userdata('______').
- attribute
- item
- key
- value
The correct syntax is $this->session->userdata('item'), where 'item' is the key or name of the session value you want to retrieve.
The use of 'Opcode caching' in CodeIgniter is beneficial for:
- Accelerating database queries
- Enhancing session management
- Improving front-end performance
- Optimizing PHP code execution
'Opcode caching' in CodeIgniter optimizes PHP code execution by caching the compiled PHP code, resulting in faster script execution and improved overall application performance.
The process of converting database result sets into custom formats is handled by the ________ method in CodeIgniter.
- convert()
- custom()
- format()
- result()
In CodeIgniter, the result() method is used to convert database result sets into custom formats, providing flexibility in handling data retrieved from the database.
For setting multiple recipients in the Email Class, the ________ function is typically used.
- add_receiver
- add_to
- set_recipient
- set_to
To set multiple recipients in the Email Class, you should use the add_to function. It enables you to add multiple email addresses as recipients for the email being sent.
The method ________ is used to update a resource in a RESTful API built with CodeIgniter.
- MODIFY
- POST
- PUT
- UPDATE
In RESTful APIs, the 'PUT' method is commonly used for updating resources. It is essential to use the correct HTTP method to maintain RESTful principles.
In CodeIgniter, how can you extend the functionalities of a third-party library without modifying its core files?
- Copy and paste the relevant code from the library and modify it directly
- Extend the library by creating a new class that inherits from the library's class
- Use hooks and events provided by CodeIgniter
- Write a separate helper function that overrides the library's functions
CodeIgniter provides a powerful feature called hooks, which allows you to extend the functionalities of a third-party library without modifying its core files. By using hooks, you can execute custom code at specific points in the CodeIgniter execution process, seamlessly integrating additional functionality without directly altering the library's code. This approach ensures maintainability and facilitates updates to the library without losing custom modifications.
Which of the following CodeIgniter features is essential for handling RESTful API requests efficiently?
- Controllers
- Libraries
- Models
- Routing
Routing is essential for handling RESTful API requests efficiently in CodeIgniter. Properly defined routes ensure that incoming requests are directed to the appropriate controllers and methods, facilitating the seamless execution of RESTful operations. Understanding and configuring routes is fundamental to building robust RESTful APIs in CodeIgniter.
After updating CodeIgniter to a new version, a previously integrated third-party payment gateway library stops functioning. The first step to troubleshoot is to check __________.
- CodeIgniter's error logs for compatibility issues
- The payment gateway provider's server status
- The server's internet connection
- The third-party library's documentation for updates
When a third-party library stops functioning after a CodeIgniter update, the first step is to consult the library's documentation for any updates or changes. This helps identify and address any compatibility issues introduced by the CodeIgniter update.
The method ________ in a controller is used to load models in CodeIgniter.
- $this->load->model()
- load->model()
- load_model
- load_model()
In CodeIgniter, to load models in a controller, you use the syntax $this->load->model('ModelName'). The load is an object, and model() is a method of that object. So, the correct syntax is $this->load->model('ModelName').
