The configuration of the log threshold in CodeIgniter is done in the ________ file.
- config.php
- database.php
- log.php
- routes.php
The configuration of the log threshold in CodeIgniter is done in the config.php file. It allows developers to set the level of errors to be logged.
To prevent direct access to a controller's method in CodeIgniter, prefix the method name with ________.
- private
- public
- secret
- underscore
To prevent direct access, prefix the method name with an underscore (_). CodeIgniter considers methods with an underscore as private, making them inaccessible via a URL. This enhances security by restricting direct access to internal methods.
For a CodeIgniter API that dynamically converts database query results to XML and JSON, the most critical aspect to optimize for performance is ________.
- Caching the API responses
- Database query optimization
- Output compression
- XML and JSON parsing
In a CodeIgniter API converting database query results to XML and JSON, the most critical aspect for performance optimization is optimizing the underlying database queries. Efficient queries contribute significantly to overall API response time.
In CodeIgniter, how are complex data relationships managed in a RESTful API serving multiple related resources?
- CodeIgniter relies on raw SQL queries for managing complex data relationships.
- CodeIgniter uses middleware for managing complex data relationships in RESTful APIs.
- CodeIgniter uses the ORM (Object-Relational Mapping) feature to handle complex data relationships in RESTful APIs.
- Complex data relationships are not supported in CodeIgniter RESTful APIs.
CodeIgniter leverages its ORM feature to manage complex data relationships in RESTful APIs efficiently. The ORM simplifies database interactions, allowing developers to define and work with relationships between different resources. This enhances the maintainability and readability of the code, making it easier to handle complex data scenarios in a RESTful API context.
The ________ function in CodeIgniter's Query Builder is essential for debugging by returning the final query string.
- debug_query()
- final_query()
- get_query()
- last_query()
The correct function for retrieving the final query string in CodeIgniter's Query Builder is last_query(). It is a valuable tool for debugging, as it allows developers to inspect the actual SQL query that was generated by the Query Builder.
________ is a technique in MVC that involves breaking down complex Views into smaller, reusable components.
- Abstraction
- Encapsulation
- Inheritance
- Templating
Templating is a technique in MVC (Model-View-Controller) that involves breaking down complex Views into smaller, reusable components. Templating simplifies the presentation layer by allowing the creation of modular and maintainable views. It promotes code reusability and separation of concerns within the application architecture.
How do migrations in CodeIgniter assist in maintaining consistency across different environments?
- Version Control
- Database Synchronization
- Schema Management
- Code Deployment
Migrations in CodeIgniter play a crucial role in managing database schema changes. The "Schema Management" option refers to the capability of migrations to update the database schema, ensuring consistency across various environments during application deployment.
In client-side validation, which language is commonly used to validate form inputs before submission?
- CSS
- JavaScript
- PHP
- Python
JavaScript is commonly used for client-side form validation. It enables validation before data submission, improving user experience by providing real-time feedback. This helps in catching errors early and reduces the load on the server for validation tasks.
For robust email integration, ________ is used to verify the sender's identity to prevent email spoofing.
- DKIM
- HMAC
- OAuth
- SSL/TLS
DomainKeys Identified Mail (DKIM) is a method used to verify the authenticity of the sender's identity in email communication. It involves adding a digital signature to the email message, which can be verified by the recipient's email server. This helps prevent email spoofing and ensures the integrity of the email content.
How does CodeIgniter's 'Hooks' feature interact with custom libraries?
- Custom libraries cannot be used in conjunction with Hooks
- Hooks are used exclusively for system-level functions
- Hooks can be used to extend the functionality of custom libraries
- Hooks have no interaction with custom libraries
CodeIgniter's Hooks feature allows the extension of custom libraries by providing points in the execution flow where additional functionality can be added.
