For advanced XML processing, CodeIgniter can be integrated with the PHP extension _______________.
- DOMDocument
- SimpleXML
- XMLReader
- XMLWriter
CodeIgniter can be integrated with the PHP extension XMLReader for advanced XML processing. XMLReader provides a stream-oriented XML parser, allowing efficient processing of large XML documents.
The ________ method in CodeIgniter is used for adding default data during seeding.
- $this->db->insert()
- $this->db->insert_batch()
- $this->db->populate()
- $this->db->seed()
In CodeIgniter, the $this->db->seed() method is used for adding default data during seeding.
Which file in CodeIgniter is typically modified to include a third-party library?
- autoload.php
- config.php
- index.php
- routes.php
The autoload.php file in CodeIgniter is typically modified to include a third-party library. This file contains the configuration for auto-loading various resources, including libraries. Adding a third-party library to the autoload configuration ensures that it is loaded automatically when the application starts, making it readily available for use throughout the code.
In CodeIgniter, where are session data typically stored by default?
- Cookies
- Database
- Server-side files
- URL parameters
By default, CodeIgniter stores session data on the server-side in files. This provides a secure and efficient way to manage user sessions without exposing sensitive information in cookies or other less secure methods.
The technique of _________ effectively limits SQL injection by stripping out SQL commands from user inputs.
- Code Obfuscation
- Data Encryption
- Input Sanitization
- Output Validation
Input Sanitization is a security technique that involves cleansing user inputs to remove potentially harmful content, such as SQL commands. This helps prevent SQL injection attacks by ensuring that only valid and safe data is processed.
What is the primary purpose of form validation in web applications?
- To create dynamic form layouts
- To encrypt form data before submission
- To ensure the form looks aesthetically pleasing
- To validate and sanitize user input
Form validation is crucial for verifying user input to prevent malicious data entry, ensuring data integrity, and enhancing security. It helps in preventing common issues like SQL injection and ensures that the received data meets specified criteria.
To maintain session data across multiple requests, CodeIgniter uses a unique identifier known as a ________.
- hash
- nonce
- session_id
- token
CodeIgniter uses a unique session_id to maintain session data across multiple requests. This identifier is used to associate the user's session data with their interactions on the site.
Where are the custom libraries stored in the CodeIgniter directory structure?
- application/libraries
- codeigniter/libraries
- custom/libraries
- system/libraries
Custom libraries in CodeIgniter are stored in the 'application/libraries' directory. This allows developers to extend the framework's functionality by creating and using their own libraries tailored to the application's needs.
