In CodeIgniter, where are log files typically stored?
- application/logs/
- logs/
- storage/logs/
- system/logs/
CodeIgniter log files are typically stored in the 'application/logs/' directory. This is the default location where the framework stores log files, and developers can access them for debugging and analysis purposes.
When experiencing database connectivity issues in a CodeIgniter application, the first place to check is the ________ settings in the database configuration file.
- Connection Settings
- Database Name
- Hostname
- Username
In the context of CodeIgniter, when facing database connectivity issues, the first place to check is the Hostname settings in the database configuration file. This setting specifies the location of your database server.
When designing a RESTful API in CodeIgniter, what format is typically used to send responses?
- CSV
- HTML
- JSON
- XML
In CodeIgniter, JSON is the typical format used to send responses in a RESTful API. JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is well-suited for representing structured data in the context of a RESTful API.
The function ________ in CodeIgniter is used to reverse all database actions since the last commit.
- reverseCommit()
- revertChanges()
- rollback()
- undoTransaction()
The rollback() function in CodeIgniter is used to reverse all database actions since the last commit. It's helpful when you want to discard changes made during a transaction.
How does the Active Record Class handle SQL injection prevention in CodeIgniter?
- By escaping user inputs using the escape() method
- By manually sanitizing input using PHP functions
- By relying on the built-in CodeIgniter firewall
- By using parameterized queries
The Active Record Class in CodeIgniter handles SQL injection prevention by using parameterized queries. This approach ensures that user inputs are treated as data rather than executable code, making it more difficult for malicious SQL injection attacks to occur. It helps prevent the injection of unauthorized SQL code into database queries, enhancing the security of the application.
How can you extend the functionalities of an existing CodeIgniter library?
- Create a new library
- Extend the library class
- Modify the core library file
- Use hooks
To extend the functionalities of an existing CodeIgniter library, you should create a new library that extends the original library class. This way, you can add or override methods to customize the behavior without modifying the core library file. Extending the library class allows you to reuse existing functionality while introducing your modifications.
CSRF attacks primarily target which aspect of a web application?
- Cross-Site Request Forgery
- Cross-Site Scripting
- Session Management
- User Authentication
Cross-Site Request Forgery (CSRF) attacks target the integrity of a web application by forcing the victim to perform unwanted actions without their consent, often leading to actions like changing passwords or making financial transactions.
What is the role of the log_message() function in CodeIgniter?
- It displays messages on the user interface for debugging.
- It logs messages to the console.
- It logs messages to the system log file.
- It sends email notifications for critical errors.
The log_message() function in CodeIgniter is used to log messages to the system log file. It's a handy way to record information or errors for later analysis, especially in production environments where direct debugging may not be possible.
In a multi-developer environment, managing __________ for third-party libraries is crucial for consistent functionality in CodeIgniter applications.
- Collaborations
- Configurations
- Dependencies
- Versions
In a multi-developer environment, managing configurations for third-party libraries is crucial for consistent functionality in CodeIgniter applications. This involves maintaining consistent settings and configurations across different development environments, ensuring that the libraries work uniformly across the team.
Which file in CodeIgniter is used to set up database connection details?
- config.php
- connections.php
- database.php
- db_config.php
In CodeIgniter, the database.php file is used to store and configure database connection details, including hostname, username, password, and database name. This centralizes database settings.
