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.
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.
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.
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.
CodeIgniter's pagination can be integrated with database results using the ________ method from the Model.
- get_pagination()
- initialize_pagination()
- paginate()
- render()
In CodeIgniter, pagination with database results is achieved using the paginate() method. This method helps in generating the necessary pagination links for displaying data across multiple pages.
During a high traffic period, a CodeIgniter application experiences slow response times. To identify the bottleneck, the developer should examine the ________ in the profiler.
- Controller Execution Time
- Database Queries
- Memory Usage
- Query Execution Time
In a high traffic scenario, examining the Controller Execution Time in the profiler helps identify bottlenecks related to the application's controller execution, providing insights into areas causing slow response times.
The CodeIgniter helper function ________ is used to set JSON content type in HTTP headers.
- json_header()
- set_content_type('application/json')
- set_json_content_type()
- set_json_header()
The set_content_type('application/json') helper function is used in CodeIgniter to set the HTTP response headers to indicate that the content being sent is in JSON format.
When configuring a CodeIgniter application for a financial service, the first step in enhancing security should focus on ________.
- Enforcing Strict Session Management
- Implementing HTTPS
- Securing Database Connections
- Validating User Inputs
In a financial service, the first step in enhancing security is often to implement HTTPS. This ensures that data transmission between the user's browser and the server is encrypted, reducing the risk of eavesdropping and man-in-the-middle attacks. HTTPS is a fundamental step in securing sensitive financial information.
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.
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.
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.
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.
