Laravel is a popular PHP web application framework known for its elegant syntax, robust features, and developer-friendly approach. It was created by Taylor Otwell and was first released in 2011. Laravel follows the model-view-controller (MVC) architectural pattern, which promotes separation of concerns and helps in organizing code.
Here are some key features and concepts of Laravel:
- Routing: Laravel provides a clean and expressive syntax for defining routes. Routes determine how URLs are handled, allowing you to map URLs to specific controllers and methods.
- MVC Architecture: Laravel follows the MVC pattern, where models represent the data and business logic, views handle the presentation layer, and controllers manage the interaction between the model and view.
- Eloquent ORM: Laravel includes Eloquent, an object-relational mapping (ORM) library that simplifies database operations. It allows you to work with databases using PHP syntax instead of writing complex SQL queries directly.
- Blade Templating Engine: Laravel uses Blade as its templating engine, which provides a simple yet powerful way to create views. Blade templates are compiled into plain PHP code and offer features like template inheritance, sections, and control structures.
- Artisan CLI: Laravel includes a command-line interface called Artisan, which provides a range of helpful commands for tasks such as generating code, managing database migrations, and running unit tests.
- Database Migrations: Laravel's migration system allows you to version control and manage your database schema. Migrations provide a convenient way to create and modify database tables using PHP code, making it easy to collaborate with other developers.
- Authentication and Authorization: Laravel provides a built-in system for user authentication and authorization. It simplifies tasks such as user registration, login, and password resets, and offers fine-grained access control through roles and permissions.
- Caching and Session Management: Laravel supports various caching drivers, including popular options like Memcached and Redis. It also provides a session handling mechanism that allows you to store user-specific data across multiple requests.
- Testing: Laravel includes built-in testing support with PHPUnit. It offers tools for writing and running unit tests, as well as integration and acceptance tests, helping ensure the stability and quality of your application.
- Community and Ecosystem: Laravel has a vibrant and active community, which contributes to its growth and provides numerous packages and extensions. The Laravel ecosystem includes libraries for tasks such as handling payments, working with APIs, and managing queues.
Overall, Laravel aims to simplify the development process by providing an expressive syntax, comprehensive tooling, and a rich set of features. Its focus on developer productivity and code elegance has made it a popular choice for building web applications with PHP.

Where to find Laravel logs?
In Laravel, logs are typically stored in the storage/logs directory of your application. By default, Laravel uses the Monolog logging library to handle logging.
Within the storage/logs directory, you will find log files organized by date. The log files have names in the format laravel-YYYY-MM-DD.log, where YYYY-MM-DD represents the date of the log file.
To view the logs, you can open the log files using a text editor or use the command line. Here are a few ways to access the log files:
- Command Line: You can navigate to your Laravel project's root directory and use a command-line tool such as
cat(for Linux/Mac) ortype(for Windows) to display the contents of the log files. For example, to view the current day's log file, you can run:
1
|
cat storage/logs/laravel-$(date +%Y-%m-%d).log
|
- Log Viewer Packages: There are also third-party packages available that provide a graphical interface to view and analyze Laravel logs. These packages often offer additional features such as filtering, searching, and highlighting of log entries. Some popular log viewer packages for Laravel include "Laravel Log Viewer" and "Laravel Log Reader".
- Log Output Channels: Laravel allows you to configure multiple log channels, which determine where logs are written. By default, the "stack" channel is used, which writes logs to the
storage/logs/laravel.logfile. However, you can configure other channels to write logs to different locations, such as databases or third-party services. Check yourconfig/logging.phpfile to see the configured log channels and their respective destinations.
It's worth noting that in production environments, it's recommended to monitor and manage your logs using a dedicated log management system or tool. These systems centralize logs from multiple servers and provide features like search, filtering, and alerting to effectively analyze and troubleshoot issues in your application.
How to host Laravel projects on AWS?
To host a Laravel project on AWS (Amazon Web Services), you can follow these general steps:
- Set up an AWS Account: If you don't already have an AWS account, sign up for one at https://aws.amazon.com/. You will need to provide billing information, but many AWS services offer a free tier that allows you to get started without incurring charges.
- Launch an EC2 Instance: EC2 (Elastic Compute Cloud) is a virtual server in the cloud. Launch an EC2 instance to run your Laravel application. Choose an instance type based on your project requirements.
- Configure Security Groups: Security groups define inbound and outbound rules for network traffic to your EC2 instance. Open the necessary ports to allow HTTP/HTTPS traffic.
- Install LAMP Stack (Linux, Apache, MySQL, PHP): Laravel is built on PHP and requires a web server, database, and PHP environment. Install the necessary components on your EC2 instance. You can use tools like Amazon Linux, Ubuntu, or CentOS as the base operating system.
- Set Up a Database: Laravel relies on a database to store data. Install and configure a database server such as MySQL or Amazon RDS (Relational Database Service) on your EC2 instance. Make sure to create a database and user credentials for your Laravel project.
- Configure Virtual Host: Set up a virtual host in the web server configuration (e.g., Apache or Nginx) to point to your Laravel project's public directory. This ensures that incoming HTTP requests are directed to your application.
- Deploy Your Laravel Project: Transfer your Laravel project files to the EC2 instance. You can use Git to clone the project repository or manually upload the files via FTP/SFTP.
- Install Dependencies: Navigate to your Laravel project directory and run
composer installto install the project dependencies specified in thecomposer.jsonfile. - Set App Key: Generate a unique application key for your Laravel project by running
php artisan key:generatein the project directory. The application key is used for encryption and should be kept confidential. - Configure Environment Variables: Update the
.envfile in your Laravel project directory with the appropriate database connection details, cache settings, and other environment-specific configurations. - Start the Web Server: Start or restart the web server (Apache or Nginx) on your EC2 instance to apply the configuration changes.
- Set Up Domain and DNS: If you have a domain name, configure DNS settings to point your domain to the public IP address of your EC2 instance. You can use Route 53, AWS's DNS service, or any other DNS provider.
- Test Your Application: Access your Laravel application through the domain or the public IP address of your EC2 instance. Verify that everything is working as expected.
Remember to consider security practices such as using HTTPS, configuring SSL certificates, and implementing firewall rules to protect your application.
Note: The specific steps may vary based on your chosen AWS services, operating system, and web server configuration. It's recommended to refer to the AWS documentation and Laravel deployment guides for detailed instructions relevant to your setup.
