What is the advantage of using $this->db->get() in CodeIgniter Models?
- It executes a raw SQL query
- It fetches records based on specified conditions
- It retrieves a single record from the database
- It returns the last inserted ID
The $this->db->get() method in CodeIgniter Models is used to fetch records from a database table based on specified conditions. It allows developers to easily perform SELECT queries by providing a clean and readable syntax. The method returns the result set as an object, making it convenient to iterate through the records. This promotes efficient and organized data retrieval within CodeIgniter Models, enhancing the overall maintainability of the application.
In CodeIgniter, unit tests are typically written in which programming language?
- JavaScript
- PHP
- Python

Unit tests in CodeIgniter are typically written in PHP, as it is the primary language for CodeIgniter development. The Unit Testing Library in CodeIgniter is designed to work seamlessly with PHP, allowing developers to write effective unit tests for their PHP code.
When a web application crashes due to a database error, the first step in exception handling should be to check the ________.
- Database connection and credentials
- Front-end code
- Network connectivity
- Server logs
In the event of a database error, checking server logs is crucial for identifying the root cause and understanding the error details. Examining front-end code or network connectivity is less likely to reveal insights into the database issue.
In CodeIgniter, Helpers are not classes but a collection of ________.
- Components
- Functions
- Libraries
- Modules
In CodeIgniter, Helpers are collections of functions, not classes. They are typically stored in the application/helpers directory.
In the context of file uploads, what is the significance of implementing a file integrity check?
- Detects and prevents tampering or corruption of uploaded files
- Ensures file confidentiality, restricts access to privileged users
- Simplifies file metadata management, improves searchability
- Verifies file format compatibility, enhances cross-browser support
Implementing a file integrity check is essential for detecting and preventing tampering or corruption of uploaded files. This ensures that the files remain intact and unaltered, maintaining the integrity of the data throughout the upload process.
How does CodeIgniter's Query Builder handle complex queries involving subqueries?
