    76. Describe the distinctions between Laravel and CodeIgniter.

    Ans:

    Laravel and CodeIgniter are both PHP frameworks but differ in several aspects. Laravel, known for its expressive syntax and modern features, embraces the MVC architecture and provides Eloquent ORM. It includes features like Blade templating, Artisan CLI, and a robust ecosystem. On the other hand, CodeIgniter follows a more straightforward, lightweight structure, offering more flexibility but fewer built-in features compared to Laravel.

    77. What is Observation?

    Ans:

    In Laravel, the term “observation” is not a standard concept. However, if you are referring to “Observers” in the context of Eloquent, they are classes that monitor Eloquent models for specific events, such as creating, updating, or deleting records. Observers allow you to encapsulate actions related to these events in separate classes, promoting clean and modular code.

    78. What does the bootstrap directory serve as?

    Ans:

    • The “bootstrap” directory in Laravel is an entry point for the framework and application.
    • It contains essential files like app.php, which initializes the Laravel application, and autoload.php, which is responsible for autoloading Composer dependencies.
    • The bootstrap process prepares the application environment, sets up error handling, and loads necessary components, making it a crucial directory for the framework’s initialization.

    79. How long is the session timeout duration by default?

    Ans:

    By default, Laravel sets the session timeout duration to 120 minutes (2 hours). This means that if a user is inactive for this period, their session will expire, and they will need to log in again for security reasons. Developers can customize the session timeout duration in the config/session.php configuration file.

    80. How may a conformed class file be deleted?

    Ans:

    • To delete a class file that adheres to Laravel’s conventions, you can use the Artisan command php artisan make controller or a similar command for other types of classes.
    • If you want to delete a controller named, for instance, ExampleController, you can run php artisan make: controller ExampleController -r -d. The -r flag removes the controller and its associated route entries, while the -d flag deletes the controller file.

    81. What folder does robot.txt reside in?

    Ans:

    In a Laravel application, the robots.txt file is typically placed in the public directory. The public directory is the web server’s document root, making it accessible to web crawlers and search engines. Placing robots.txt in the public directory allows developers to control the behavior of web crawlers and specify which parts of the site should be crawled or excluded.

    82. Describe the PHP API path.

    Ans:

    The PHP API path refers to the Route or URL endpoint through which an application’s API (Application Programming Interface) can be accessed. In Laravel, these paths are defined in the routes/api.php file. Developers use this file to specify the routes and associated controller methods for API requests. The PHP API path is crucial for interacting with and consuming data from the application through a standardized interface.

    83. What’s a route called?

    Ans:

    In Laravel, a route is commonly referred to as a defined URL pattern that points to a specific controller method or closure. Routes map incoming HTTP requests to the corresponding logic that should be executed. Laravel supports named routes, allowing developers to reference routes by name rather than URL, enhancing code readability and maintainability.

    84. What is software that is open source?

    Ans:

    Applications or programs with publicly available source code are called open-source software. The source code is openly seen, edited, and distributed by users. This is the approach taken by the open-source PHP web framework Laravel.

    Laravel, being an open-source PHP web framework, follows this model. Open source fosters collaboration, transparency, and community-driven development, allowing developers worldwide to contribute to and benefit from the software.

    85. Describe the Laravel login.

    Ans:

    • The Laravel login process involves several components. First, Laravel provides a pre-built authentication system with controllers, views, and routes. Developers can use the make: auth Artisan command to scaffold the necessary components.
    • Users can access the login form, enter credentials, and submit the form. Laravel validates the credentials and, if correct, authenticates the user. Successful authentication grants access to protected routes and resources.

    86. Describe Localization.

    Ans:

    Localization is modifying your program to run in many languages and be used by people worldwide. Because Laravel offers a straightforward mechanism to obtain text in many languages, you may quickly swap between languages according to user preferences. Localization files are typically stored in the resources/lang directory. Developers can define key-value pairs for each language supported. The ability to offer information in the user’s preferred language is made possible by Laravel’s localization tools, which are crucial for creating apps that serve a broad user base.

    87. Explain what Laravel hashing is.

    Ans:

    • Laravel provides a suite of secure Bcrypt and Argon2 hashing algorithms for storing passwords.
    • When a password is hashed, it is converted into a secure string that is safe to store in a database.
    • Laravel’s hashing system does not allow the original password to be recovered once hashed, enhancing security.
    • The Hash facade provides methods to hash and verify passwords securely.
    • This approach ensures that user passwords are never stored in plain text, safeguarding them against unauthorized access.

    88. Describe how Laravel handles encryption and decoding.

    Ans:

    Laravel provides a suite of secure Bcrypt and Argon2 hashing algorithms for storing passwords. When a password is hashed, it is converted into a secure string that is safe to store in a database. Laravel’s hashing system does not allow the original password to be recovered once hashed, enhancing security. The Hash facade provides methods to hash and verify passwords securely. This approach ensures that user passwords are never stored in plain text, safeguarding them against unauthorized access.

    89. How are data and opinions shared?

    Ans:

    Laravel allows accessible data sharing across all views, enhancing the framework’s flexibility and reducing code duplication.Using view composers and view shares, developers can specify data available to all views, making it easier to display user information, settings, or any global data required by the application. This capability simplifies the management of shared data across different parts of an application, ensuring consistency and reducing the need for repetitive code.

    90. Describe the web.php route?

    Ans:

    In Laravel, the web.php file within the routes directory is where you define all the web routes for your application. These routes are designed to serve HTML pages and handle form submissions. Routes defined in web.php automatically receive session state, CSRF protection, and cookie encryption. This file is the starting point for routing HTTP requests to controllers or closure functions, making it central to the web application’s functionality.
