During a security audit, it's discovered that large file uploads are causing server crashes. This issue relates to ________.
- Cross-Site Scripting (XSS)
- Denial of Service (DoS) Attacks
- Resource Limitations
- SQL Injection
Server crashes due to large file uploads typically point to resource limitations such as exceeding upload size limits. Managing server resources is crucial to prevent performance issues and potential crashes.
________ exceptions are used to handle errors that are recoverable during runtime.
- Checked
- Custom
- Fatal
- Unchecked
Checked exceptions are used to handle errors that are recoverable during runtime. These exceptions must be explicitly caught or declared by the method.
To optimize a CodeIgniter application's performance, a developer focuses on the sections with the longest execution time in the ________ report.
- Benchmark
- Error Handling
- Profiler
- Routing
The Benchmark report in CodeIgniter highlights the execution time of different sections, allowing developers to identify and optimize areas with the longest execution time, ultimately improving the overall performance of the application.
________ is a critical aspect in CodeIgniter that needs optimization for handling high traffic.
- Error Handling
- Routing
- Session Handling
- Templating
Session handling is a crucial aspect in CodeIgniter, especially when dealing with high traffic. Optimizing session management involves efficient storage, retrieval, and handling of user session data to ensure scalability and performance.
The practice of writing tests for the smallest pieces of code in a system is known as ________ testing in CodeIgniter.
- Integration
- Regression
- System
- Unit
In CodeIgniter, writing tests for the smallest pieces of code is known as unit testing. It involves testing individual units or components in isolation to ensure they function as expected. This helps identify and fix bugs early in the development process, contributing to overall code reliability and maintainability.
To handle complex scenarios, CodeIgniter's database configuration supports the use of ________ to extend its capabilities.
- drivers
- extensions
- features
- plugins
To handle complex scenarios, CodeIgniter's database configuration supports the use of drivers to extend its capabilities. Drivers allow developers to use different types of databases or customize database functionality as needed.
In CodeIgniter's Query Builder, what method is used to insert a batch of data into a database table?
- batchInsert()
- bulkInsert()
- insertBatch()
- multiInsert()
The method used to insert a batch of data into a database table in CodeIgniter's Query Builder is insertBatch(). This is handy when you need to insert multiple records at once.
For advanced dependency management in custom libraries, CodeIgniter developers often use the ________ pattern.
- Dependency Injection
- Factory Pattern
- Observer Pattern
- Singleton Pattern
In CodeIgniter, the Factory Pattern is commonly employed for advanced dependency management in custom libraries. It allows developers to create objects without specifying the exact class of the object that will be created. This promotes flexibility and easier maintenance.
In CodeIgniter, how can you redirect the user to a different method within the same controller?
- $this->load->redirect('method_name')
- $this->load->set('location', 'method_name')
- $this->load->view('method_name')
- $this->redirect('method_name')
To redirect a user to a different method within the same controller in CodeIgniter, you can use $this->redirect('method_name'). This method simplifies the process of redirecting and improves code readability.
What is the primary purpose of pagination in a CodeIgniter application?
- Improving user experience with faster page loads
- Organizing data for better readability
- Simplifying code structure for better maintenance
- Splitting large datasets into smaller chunks
Pagination in CodeIgniter is primarily used to split large datasets into smaller, more manageable chunks. This enhances the user experience by enabling faster page loads and makes it easier to navigate through large sets of data.
