Answer
Composer in Laravel is a crucial tool for managing dependencies in PHP projects. Here's a concise overview:
1. **Dependency Management:** Composer allows you to declare and manage the libraries your Laravel project depends on, streamlining the integration of third-party packages.
2. **Installation in Laravel:**
- For Laravel 4.2, Composer is used to manage dependencies, and you can download the composer.phar [2].
- Laravel 5.0 onwards also relies on Composer for dependency management [4].
- Laravel 7.x and 10.x emphasize the importance of having Composer installed before using Laravel [6] [7].
3. **Installation Steps:**
- After installing Composer, download Laravel, and extract it. Set the application key to enhance security [1].
4. **Command Line Usage:**
- Composer operates through the command line, allowing you to install and manage dependencies efficiently [8].
In summary, Composer simplifies Laravel project setup and maintenance by handling dependencies effectively.
