The main goal of Composer, a popular PHP dependency management tool, is to simplify the installation and updating of project dependencies. Based on the project parameters, it will identify which extra packages are needed for a particular project and install them for you using the appropriate versions. Composer is also often used for bootstrapping new projects that are based on popular PHP frameworks such as Symfony and Laravel.

Step 1: Visit the following website to download

Run this command
