During a system upgrade, a developer uses ________ in CodeIgniter to ensure database compatibility with new features.
- controllers
- migrations
- models
- seeds
In CodeIgniter, migrations are used to version control the database schema. During a system upgrade, a developer can create and run migrations to modify the database structure, ensuring compatibility with new features.
In CodeIgniter, the ________ method allows controllers to handle multiple HTTP verbs in a single method.
- _remap
- handleHTTP
- multiHTTP
- requestMethod
In CodeIgniter, the requestMethod method allows controllers to handle multiple HTTP verbs (GET, POST, etc.) in a single method. This is useful for consolidating different actions into a single controller method, improving code organization.
How does the Email Class handle attachments in an email?
- Attachments are automatically added if the email body contains file paths.
- Attachments are handled by specifying file paths directly in the to() method.
- Attachments are handled using the attach() method, which attaches files to the email.
- The Email Class doesn't support attachments.
The Email Class in CodeIgniter handles attachments using the attach() method, allowing you to include files in your emails. This method allows you to specify the file path and other relevant details.
In many programming languages, unhandled exceptions are caught by a global ________ handler.
- ErrorHandler
- Exception
- ExceptionHandler
- GlobalHandler
In many programming languages, unhandled exceptions are caught by a global exception handler. This handler can be defined to manage unexpected situations and prevent abrupt termination of the program. It plays a crucial role in gracefully handling errors at a higher level.
________ is a technique used to verify whether an input adheres to a specified format, like an email address.
- Data Binding
- Input Sanitization
- Regular Expression
- Typecasting
Regular expressions are often used for input validation, allowing developers to define specific patterns that the input must match, such as email addresses.
During a penetration test, it's found that a script from an external domain is executing malicious actions. This indicates a potential ________ vulnerability.
- Cross-Origin Resource Sharing (CORS)
- Cross-Site Request Forgery (CSRF)
- Cross-Site Scripting (XSS)
- SQL Injection
The presence of a script from an external domain executing malicious actions suggests a Cross-Site Scripting (XSS) vulnerability, where untrusted data is rendered without proper validation or escaping.
In a multi-step form, ensuring that each step is validated before proceeding to the next is an example of ________ validation.
- Front-to-back
- Incremental
- Sequential
- Step-wise
Sequential validation ensures that each step is validated before moving to the next. It ensures data integrity throughout the form submission process.
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.
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.
