The process of converting database result sets into custom formats is handled by the ________ method in CodeIgniter.

  • convert()
  • custom()
  • format()
  • result()
In CodeIgniter, the result() method is used to convert database result sets into custom formats, providing flexibility in handling data retrieved from the database.

For setting multiple recipients in the Email Class, the ________ function is typically used.

  • add_receiver
  • add_to
  • set_recipient
  • set_to
To set multiple recipients in the Email Class, you should use the add_to function. It enables you to add multiple email addresses as recipients for the email being sent.

The method ________ is used to update a resource in a RESTful API built with CodeIgniter.

  • MODIFY
  • POST
  • PUT
  • UPDATE
In RESTful APIs, the 'PUT' method is commonly used for updating resources. It is essential to use the correct HTTP method to maintain RESTful principles.

In CodeIgniter, how can you extend the functionalities of a third-party library without modifying its core files?

  • Copy and paste the relevant code from the library and modify it directly
  • Extend the library by creating a new class that inherits from the library's class
  • Use hooks and events provided by CodeIgniter
  • Write a separate helper function that overrides the library's functions
CodeIgniter provides a powerful feature called hooks, which allows you to extend the functionalities of a third-party library without modifying its core files. By using hooks, you can execute custom code at specific points in the CodeIgniter execution process, seamlessly integrating additional functionality without directly altering the library's code. This approach ensures maintainability and facilitates updates to the library without losing custom modifications.

In high-risk transactions, payment gateways might implement ________ as an additional verification step.

  • Biometric Verification
  • Risk Scoring
  • Secure Socket Layer (SSL)
  • Two-Factor Authentication
In high-risk transactions, payment gateways often implement risk scoring as an additional verification step. Risk scoring involves assessing various parameters such as transaction history, user behavior, and geolocation to determine the likelihood of a transaction being fraudulent. This adds an extra layer of security in sensitive transactions.

Which of the following CodeIgniter features is essential for handling RESTful API requests efficiently?

  • Controllers
  • Libraries
  • Models
  • Routing
Routing is essential for handling RESTful API requests efficiently in CodeIgniter. Properly defined routes ensure that incoming requests are directed to the appropriate controllers and methods, facilitating the seamless execution of RESTful operations. Understanding and configuring routes is fundamental to building robust RESTful APIs in CodeIgniter.

After updating CodeIgniter to a new version, a previously integrated third-party payment gateway library stops functioning. The first step to troubleshoot is to check __________.

  • CodeIgniter's error logs for compatibility issues
  • The payment gateway provider's server status
  • The server's internet connection
  • The third-party library's documentation for updates
When a third-party library stops functioning after a CodeIgniter update, the first step is to consult the library's documentation for any updates or changes. This helps identify and address any compatibility issues introduced by the CodeIgniter update.

The method ________ in a controller is used to load models in CodeIgniter.

  • $this->load->model()
  • load->model()
  • load_model
  • load_model()
In CodeIgniter, to load models in a controller, you use the syntax $this->load->model('ModelName'). The load is an object, and model() is a method of that object. So, the correct syntax is $this->load->model('ModelName').

In CodeIgniter, which log level is recommended for a production environment?

  • DEBUG
  • ERROR
  • INFO
  • WARNING
In a production environment, it's recommended to set the log level to ERROR to focus on critical issues that need attention. Debug and info messages might reveal too much information.

In CodeIgniter, what is the primary purpose of a Helper?

  • Encapsulates controller logic
  • Enhances and extends the functionality of views
  • Handles routing and URL manipulation
  • Manages database operations
CodeIgniter Helpers are utility functions that provide common functionality, such as form handling, URL manipulation, and more, to enhance and extend the functionality of views. They are not directly involved in database operations or routing.
