The configuration for error logging level is set in the ______ file.
- config.php
- database.php
- error.php
- log.php
In CodeIgniter, the configuration for error logging level is set in the log.php configuration file. You can define the error logging threshold in this file to control which types of errors should be logged, helping you manage the log information based on your application needs.
For complex query handling in a RESTful API with CodeIgniter, the ________ pattern is often utilized.
- Adapter
- Observer
- Repository
- Singleton
In CodeIgniter, the Repository pattern is commonly used for handling complex queries in a RESTful API. This pattern helps in separating the logic that retrieves the data from the underlying storage, providing a clean and organized way to manage queries.
The assertion method used to check if a function returns a boolean true is called ________.
- assert_bool
- assert_boolean
- assert_true
- assert_truthy
In CodeIgniter, the assertTrue method in PHPUnit is used to assert that a certain expression evaluates to true. This is commonly used to verify that a function returns a boolean true value.
Advanced XSS protections often involve the use of ________, which restricts scripts based on their source and inline script execution.
- Content Security Policy (CSP)
- Cross-Origin Resource Sharing (CORS)
- Cross-Site Request Forgery (CSRF)
- Cross-Site Scripting (XSS)
Content Security Policy (CSP) is a security standard that helps prevent XSS by defining trusted sources for content. This restricts scripts based on their source and inline script execution.
In a scenario where a CodeIgniter application needs to switch databases based on user roles, the database switching is typically done in the ________.
- Controller
- Database Configuration
- Model
- View
In CodeIgniter, database switching based on user roles is typically done in the Database Configuration file. This file allows you to set different database connections and switch between them based on your application's requirements.
Describe a scenario where creating a custom Helper in CodeIgniter would be beneficial over using built-in Helpers.
- Code Reusability Across Projects
- Performance Optimization
- Specific Application Requirements
- Standardization of Code
Creating a custom Helper in CodeIgniter becomes beneficial when specific application requirements cannot be met by built-in Helpers. Custom Helpers allow developers to tailor functionality to the unique needs of their projects. This approach promotes code reusability across different projects, ensures optimal performance by excluding unnecessary functionalities, and facilitates the standardization of code according to project-specific criteria.
Regular expressions are often used in _________ to filter out harmful SQL patterns.
- Data encryption
- Form handling
- Input validation
- Query optimization
Regular expressions are commonly employed in input validation to filter out harmful SQL patterns. They help ensure that user inputs adhere to expected formats, preventing potential SQL injection attacks.
How can you get the last executed query as a string in CodeIgniter's Query Builder?
- getLastExecutedQuery()
- getLastQuery()
- getLastStatement()
- getRecentQuery()
To get the last executed query as a string in CodeIgniter's Query Builder, you use the getLastExecutedQuery() method. This is useful for debugging and logging purposes.
In a CodeIgniter application, when a user requests a report, the Model efficiently handles this by using ________ to aggregate data.
- Active Record
- Controller
- Helper
- Query Builder
In CodeIgniter, the Query Builder is a powerful feature that allows the Model to efficiently handle data aggregation, providing a flexible and easy-to-use way to construct database queries.
Which Query Builder method in CodeIgniter is used to join two tables?
- combine()
- connect()
- join()
- merge()
The correct method to join two tables in CodeIgniter's Query Builder is join(). This method allows you to specify the tables and conditions for the join.
