In a RESTful API developed with CodeIgniter, a sudden increase in response time for resource retrieval suggests an issue with ________.
- Database queries
- Front-end rendering
- Middleware processing
- Network latency
When there is a sudden increase in response time for resource retrieval in a CodeIgniter RESTful API, it often indicates a problem with database queries. This could be due to inefficient queries, lack of indexing, or other database-related issues affecting the API's performance. Monitoring and optimizing database queries are crucial in such scenarios.
How does token-based validation in forms help in preventing CSRF attacks?
- Authenticates user identity
- Encrypts user data
- Ensures proper input validation
- Mitigates Cross-Site Request Forgery
Token-based validation in forms is a security measure that mitigates Cross-Site Request Forgery (CSRF) attacks. CSRF attacks involve unauthorized actions being performed on behalf of a user without their consent. By using tokens, a unique identifier is generated for each user session, making it challenging for attackers to forge requests.
__________ is a key consideration when updating a third-party library to ensure minimal disruption in a CodeIgniter application.
- Compatibility
- Dependency
- Extension
- Integration
Compatibility is a key consideration when updating a third-party library in a CodeIgniter application. This ensures that the updated library works seamlessly with the existing CodeIgniter codebase, minimizing disruptions and maintaining application stability.
What is the difference between the get() and get_where() methods in the Active Record Class?
- Both methods are identical in functionality
- The get() method retrieves all records from the table
- The get_where() method is used for complex conditional queries
- get() is used for SELECT * queries, get_where() for specific conditions
The get() method retrieves all records from the table, while the get_where() method is specifically designed for queries with complex conditions. The get_where() method allows you to specify conditions directly in the method call.
_______________ is a CodeIgniter feature that aids in the efficient streaming of large JSON datasets.
- JSONIterator
- JSONSerialization
- JSONStreamer
- JsonResponse
CodeIgniter's JSONStreamer feature aids in the efficient streaming of large JSON datasets. It's designed for handling large amounts of JSON data in a memory-efficient manner during streaming.
In CodeIgniter, the default timezone is set in the ________ file.
- config.php
- constants.php
- settings.php
- timezone.php
The default timezone in CodeIgniter is set in the config.php configuration file. You can find the 'date.timezone' setting in this file, allowing you to configure the default timezone for your application.
How does federated identity management play a role in social media integration?
- Allows websites to share user authentication information with social media platforms
- Authenticates users only through email verification
- Enables users to use their existing social media credentials to access a website
- Manages identity across multiple, unrelated domains
Federated identity management allows users to use their existing social media credentials to access a website. This streamlines the login process and enhances user experience. It involves the cooperation of multiple identity management systems.
The process of defining the sender's email and name is done using the ________ method in the Email Class.
- define_sender
- from
- sender
- set_sender
The correct method to define the sender's email and name in the Email Class is set_sender. This method allows you to specify both the email address and the name of the sender for the outgoing email.
What does CRUD stand for in the context of database operations?
- Create
- Delete
- Read
- Update
CRUD stands for Create, Read, Update, and Delete. It represents the four basic operations performed on data in a database. Create is used to add new records, Read retrieves data, Update modifies existing records, and Delete removes records. This concept is fundamental to database management and is widely used in CodeIgniter for database operations.
A developer encounters a non-descriptive error while running a CodeIgniter application. The first step to investigate is to check the ______.
- Check the server logs
- Examine the application's code
- Inspect the browser console
- Review the database configuration
When encountering a non-descriptive error, checking the server logs is crucial for identifying any issues or error messages that may provide insights into the problem.
