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.
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.
In what scenario is it advisable to use the escape methods in CodeIgniter's Query Builder?
- When building queries without the need for variable interpolation
- When dealing with static data that doesn't change frequently
- When incorporating user input into SQL queries to prevent SQL injection
- When performing read-only operations on the database
It's advisable to use escape methods in CodeIgniter's Query Builder when incorporating user input to prevent SQL injection and enhance security.
How does Test Driven Development (TDD) approach integrate with CodeIgniter's unit testing?
- CodeIgniter provides built-in support for TDD, allowing developers to write tests before the actual code.
- CodeIgniter's unit testing is a separate process from TDD.
- TDD is not supported in CodeIgniter.
- TDD is only suitable for other PHP frameworks.
CodeIgniter supports Test Driven Development by facilitating the creation of tests before the implementation of code. This promotes a more robust and reliable development process by ensuring that the code meets the specified requirements from the outset.
In CodeIgniter, data passed to the view are accessible as ________ variables.
- Controller
- Global
- Local
- View
In CodeIgniter, the data passed to the view is accessible as global variables. These variables are directly accessible in the view file without any prefix, making it convenient to display the data.
A developer needs to optimize a query that fetches large datasets by applying filters. The optimal approach involves using ________ in CodeIgniter's Query Builder.
- filter()
- optimize()
- select()
- where()
To optimize a query and fetch large datasets by applying filters, the where() method in CodeIgniter's Query Builder is crucial. It allows developers to apply conditions to narrow down the result set efficiently.
CodeIgniter's Query Builder allows grouping conditions using the ________ method for complex queries.
- group()
- group_by()
- group_conditions()
- group_start()
The correct method for grouping conditions in CodeIgniter's Query Builder is group_start(). This method is used to open a group of conditions that will be enclosed within parentheses. It is particularly useful for creating complex queries with multiple conditions.
To use multiple databases in CodeIgniter, what method is typically employed in the controller?
- Defining multiple $db arrays in the config file
- Initializing a new instance of the database class
- Loading a different configuration file
- Using the model's load method with database parameters
To use multiple databases in CodeIgniter, a common method is to load a different database configuration in the controller by using $this->load->database('second_db', TRUE). This initializes a new database connection.
In optimizing a CodeIgniter e-commerce site, focusing on ________ will most effectively enhance user experience during high-traffic events.
- Caching Strategies
- Code Compression
- URL Routing
- User Authentication
Caching strategies play a vital role in optimizing an e-commerce site. By caching frequently accessed data, such as product information, the site can serve content more quickly during high-traffic periods, significantly improving user experience.
How can Helpers be made globally available in CodeIgniter without loading them in each controller?
- Creating a Custom Library
- Editing the Core Configuration File
- Using Autoload Config
- Utilizing Composer
Helpers can be made globally available in CodeIgniter by using the Autoload Config. By configuring the autoload.php file, developers can specify which Helpers should be loaded globally without the need to include them in each controller separately. This approach enhances code organization and ensures that essential Helpers are readily available throughout the application.
Custom configuration files in CodeIgniter are stored in the ________ directory.
- application/config
- application/configuration
- application/preferences
- application/settings
In CodeIgniter, custom configuration files are stored in the 'application/config' directory. This directory holds various configuration files that control the behavior of the framework and the user's application.
When implementing a master page layout in CodeIgniter, the ________ method is often used to incorporate multiple views.
- load->layout
- load->page
- load->template
- load->view
The load->view method in CodeIgniter is commonly used to incorporate multiple views and implement a master page layout. By loading different views within a controller, you can create a structured layout for your web pages, enhancing code organization and reusability.
