________ is a technique used to verify whether an input adheres to a specified format, like an email address.
- Data Binding
- Input Sanitization
- Regular Expression
- Typecasting
Regular expressions are often used for input validation, allowing developers to define specific patterns that the input must match, such as email addresses.
The ________ method in CodeIgniter is crucial for handling conditional rollbacks in transactions.
- commit
- end_transaction
- rollback
- set_rollback
The "set_rollback" method in CodeIgniter is crucial for handling conditional rollbacks in transactions. It allows you to set a flag that determines whether a transaction should be rolled back or not. This is useful when dealing with conditional logic within a transaction.
What is the primary purpose of session management in web applications?
- Enhancing security by storing user data securely
- Facilitating server-side rendering
- Improving database performance
- Managing and persisting user data across multiple requests
Session management is crucial for persisting user-specific data across different requests. It allows web applications to maintain stateful interactions with users by storing data like user preferences, authentication details, etc. This enhances the user experience and makes it easier to manage user-related information.
To add custom query parameters to pagination links, the ________ configuration option is used.
- custom_params
- page_query_string
- link_params
- query_options
The page_query_string configuration option in CodeIgniter allows the addition of custom query parameters to pagination links, facilitating customization based on specific requirements.
In a scenario where a user logs in through a social media account and their profile picture and bio are automatically updated in the app, this process is known as ________.
- Data Synchronization
- OAuth Integration
- Social Media Scraping
- User Profiling
The correct option is "Data Synchronization." This process involves updating user data in the app in real-time based on changes in the external source, in this case, the social media account. It ensures that the app reflects the latest information from the user's profile.
How does exception handling contribute to a program's robustness?
- Enhances code reliability by handling unexpected errors gracefully
- Increases code complexity and performance issues
- Only applicable in certain programming languages
- Reduces the need for testing
Exception handling improves a program's robustness by allowing it to gracefully handle unexpected errors. It prevents abrupt termination and provides mechanisms to recover or log errors, contributing to overall code reliability.
In a multi-threaded application, an exception in one thread should be handled in a way that ________.
- Does not affect other threads
- Pauses all threads until resolved
- Prompts the user for a resolution
- Terminates the entire application
Handling an exception in a way that does not affect other threads is essential in a multi-threaded application. Pausing or terminating the entire application is generally not recommended as it could disrupt other threads and impact the overall application stability.
Database ________ is a process of inserting initial data into the database for testing purposes.
- Insertion
- Populating
- Seeding
- Seeding:insert
Database Seeding is the process of inserting initial data into the database for testing purposes. It helps to populate the database with dummy data for testing and development.
When storing sessions in a database in CodeIgniter, the table must have a column named ________ to store session data.
- data
- session_content
- session_data
- session_payload
CodeIgniter expects a column named session_data to store session information when using a database to store sessions. The framework uses this column to store serialized session data securely. It is crucial to have this column named correctly for CodeIgniter to work seamlessly with database-backed sessions.
For tracking memory usage and execution time, CodeIgniter developers often use ______ markers.
- Benchmark
- Logger
- Profiler
- Trace
CodeIgniter's Profiler class allows developers to mark specific points in the code to track memory usage and execution time. These markers aid in performance analysis and optimization.
