What advanced technique does CodeIgniter provide for managing complex database schemas?
- Data Seeding
- Database Migrations
- Eloquent ORM
- Query Caching
CodeIgniter provides the concept of Database Migrations, allowing developers to version control database schema changes and manage complex database schemas over time. This ensures smooth database schema evolution as the application evolves.
What is the role of resource controllers in RESTful API development using CodeIgniter?
- Resource controllers are only used for authentication in RESTful APIs.
- Resource controllers are optional in CodeIgniter RESTful API development.
- Resource controllers in CodeIgniter handle the CRUD operations for a specific resource in a RESTful API.
- Resource controllers manage database connections for RESTful APIs.
Resource controllers play a crucial role in handling CRUD operations for a specific resource in a RESTful API developed using CodeIgniter. They facilitate the implementation of RESTful principles, enabling easy management of resources through standard HTTP methods like GET, POST, PUT, and DELETE.
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.
In CodeIgniter, which method is recommended for sending form data to a view?
- $this->form->open()
- $this->load->form()
- $this->load->form_open()
- $this->load->helper('form')
The recommended method for sending form data to a view in CodeIgniter is by loading the form helper using $this->load->helper('form'). This helper provides functions to create form elements and handle form submissions efficiently.
To simulate a database in unit tests, CodeIgniter recommends using ________.
- FakeDatabase
- MockDatabase
- SimDatabase
- TestDatabase
CodeIgniter suggests using the CIUnitTestCase class and the DBUnitTestCaseTrait trait to simulate a database in unit tests. This helps in testing database interactions without affecting the actual database.
How does the 'third_party' directory differ from the 'libraries' directory in CodeIgniter?
- It contains external libraries and packages.
- It holds third-party assets like images and styles.
- It is a reserved directory for future framework use.
- It is used for storing custom CodeIgniter libraries.
The 'third_party' directory is intended for external libraries and packages, while the 'libraries' directory is meant for custom libraries created within the application.
A developer needs to add a new table to the database without disrupting the existing data. The first step they should take is to create a ________.
- Controller
- Migration
- Model
- View
In CodeIgniter, when adding a new table to the database without disrupting existing data, developers should create a migration. Migrations allow for version control of the database schema, enabling easy management of changes while preserving data integrity.
What is the minimum PHP version required to install CodeIgniter 4?
- 5.6
- 7
- 7.2
- 7.4
CodeIgniter 4 requires a minimum PHP version of 7.2. It utilizes features and improvements introduced in PHP 7.2 and later, ensuring compatibility and taking advantage of the latest language enhancements.
________ 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.
