The use of ________ in payment gateways helps in managing recurring payments efficiently.
- Authentication
- Encryption
- Secure Protocols
- Tokenization
Tokenization is a crucial feature in payment gateways for managing recurring payments efficiently. It involves replacing sensitive payment information with a unique token, enhancing security and simplifying the process of handling recurring transactions without exposing confidential data.
In CodeIgniter, the use of ________ headers can help prevent Clickjacking attacks.
- X-Frame-Options
- X-Content-Type-Options
- Strict-Transport-Security
- Content-Security-Policy
CodeIgniter recommends setting the X-Frame-Options header to prevent Clickjacking attacks. This header controls whether a browser should be allowed to render a page in a frame or iframe, adding a security layer against UI redressing attacks.
In the database configuration, the ________ setting determines whether to use persistent database connections.
- connection_persistence
- pconnect
- persistent
- use_persistent
In CodeIgniter's database configuration, the pconnect setting determines whether to use persistent database connections. Setting it to TRUE enables persistent connections, while setting it to FALSE disables them. Persistent connections help reduce the overhead of establishing a new connection for each request, improving performance.
When refactoring a CodeIgniter application for better performance, the first step is to ensure existing unit tests ________.
- Cover all possible edge cases
- Execute successfully without failures
- Include extensive documentation
- Update to the latest CodeIgniter version
The first step in refactoring for better performance is to ensure that existing unit tests execute successfully without failures. This helps ensure that the changes made do not introduce new issues and that the application remains stable.
What is the primary HTTP method used to retrieve data in a RESTful API developed with CodeIgniter?
- DELETE
- GET
- POST
- PUT
In a RESTful API, the primary HTTP method used to retrieve data is GET. This method is commonly used for reading resources and does not modify the server's state. In CodeIgniter, you would design your API endpoints to respond to GET requests for data retrieval.
How can you enable profiler in CodeIgniter for debugging purposes?
- $this->config->item('enable_profiler', TRUE);
- $this->enable_profiler(TRUE);
- $this->load->library('profiler');
- $this->output->enable_profiler(TRUE);
To enable the profiler in CodeIgniter, you use the $this->output->enable_profiler(TRUE); method. This will display a report at the bottom of your pages, showing benchmark results, queries, and more.
What is the primary purpose of exception handling in software development?
- To enhance code execution speed
- To handle unforeseen runtime errors
- To improve code readability
- To replace regular error messages
Exception handling in software development serves the purpose of managing unforeseen runtime errors that may occur during program execution. It allows developers to gracefully handle and recover from unexpected issues, preventing the application from crashing abruptly.
In CodeIgniter, the class used for file uploads is named ________.
- FileHandler
- FileUploader
- Upload
- UploadHandler
In CodeIgniter, the class responsible for handling file uploads is named "Upload." Developers use this class to manage and validate uploaded files seamlessly.
Which feature in CodeIgniter allows you to track the performance of database queries?
- Active Record
- Database Caching
- Database Profiler
- Query Builder
CodeIgniter's Database Profiler allows you to track the performance of database queries. It helps in identifying slow queries and optimizing database interactions for better application performance.
To analyze recurring errors in a CodeIgniter application, the developer should primarily check the ________.
- Apache Server Logs
- Application Logs
- CodeIgniter Profiler
- Database Queries
Checking the application logs in CodeIgniter is a crucial step in analyzing recurring errors. The logs provide detailed information about errors, warnings, and other important events, helping developers identify and fix issues efficiently.
