In a blog application, when a post is updated, the Active Record Class method sequence that is most appropriate is: ________.

  • set()
  • update()
  • update_batch()
  • where()
The correct sequence for updating a record in CodeIgniter using Active Record is set() to set the values, followed by where() to specify the condition, and then update() to perform the update. update_batch() is used for updating multiple records simultaneously.

CodeIgniter's Model method ________ is used for pagination of query results.

  • limit()
  • paginate()
  • slice()
  • split()
The paginate() method in CodeIgniter Models is used for pagination of query results. It helps in breaking down large result sets into smaller, more manageable pages.

To ensure that sensitive data is not logged, CodeIgniter recommends disabling ________ in production environments.

  • Caching
  • Database Queries
  • Error Logging
  • Profiler
CodeIgniter advises disabling the profiler in production to prevent sensitive information, such as query details, from being logged. The profiler is a debugging tool and should not be enabled in a live environment for security reasons.

When integrating a third-party library that requires database interactions, which CodeIgniter feature is most crucial for seamless integration?

  • Database Configuration
  • Database Library
  • Database Seeder
  • Query Builder Class
When integrating a third-party library that requires database interactions, the most crucial CodeIgniter feature is the Database Library. This library provides a set of functions for interacting with the database, making it essential for seamless integration with third-party libraries that involve database operations.

What is the difference between an error and an exception in programming?

  • Errors are compile-time issues, while exceptions are runtime issues
  • Errors are handled by the programmer, while exceptions are handled by the system
  • Errors are intentional, while exceptions are unintentional
  • Errors are non-recoverable, while exceptions can be handled and recovered from
The key distinction between errors and exceptions lies in their recoverability. Errors are typically non-recoverable issues that result from severe problems, such as out-of-memory errors. On the other hand, exceptions are designed to be caught and handled, allowing for graceful recovery from unexpected situations during runtime.

In CodeIgniter, which security practice is recommended for handling passwords?

  • Encrypting passwords with a custom algorithm
  • Storing plain text passwords
  • Using the MD5 hashing algorithm
  • Utilizing the bcrypt hashing algorithm
CodeIgniter recommends utilizing the bcrypt hashing algorithm for password security. Bcrypt is a strong, adaptive hashing algorithm that includes a salt, making it resistant to brute-force and rainbow table attacks. Storing plain text passwords or using weak hashing algorithms is not recommended for secure password management.

When chaining methods in Active Record Class, the order of ________ and ________ methods is crucial for correct query formation.

  • from, limit
  • limit, order_by
  • select, where
  • where, order_by
The order of limit and order_by methods is crucial when chaining methods in Active Record Class. Incorrect order can lead to unexpected query results.

How does 3D Secure technology in payment gateways contribute to fraud prevention?

  • Address Verification System (AVS)
  • Authentication of Cardholder
  • Encryption of Transaction Data
  • Tokenization of Card Information
3D Secure technology contributes to fraud prevention by authenticating the cardholder during the transaction. This adds an extra layer of security, making it more difficult for unauthorized users to make fraudulent transactions, thus enhancing the overall security of online payments.

In CodeIgniter, how can you specify dependencies between different migrations?

  • By creating a separate configuration file
  • By defining dependencies in the migration command
  • It's not possible to specify dependencies
  • Using the $depends property in migration files
CodeIgniter allows you to specify dependencies between migrations using the $depends property in migration files. This helps in ensuring that migrations are executed in a specific order, addressing any dependencies between them.
