The dependency manager allows you to create and retrieve libraries in your PHP projects from the packagist.org library. Packagist.org itself is a site that provides many libraries that you can use. With the help of these tools You can connect to the packagist.org site and you can download and upload the library.

  • Most repositories, such as Github, include links or commands ready to simplify downloading the appropriate bundle via composer.
  • Can result in a hierarchical structure, for example: A national repository website may require a continental repository site (child-parent dependency), while being a child of the frameworks repository site (a parent for the previous parent). In this way the dependency structure is created.

Why Should Developers Use the Despendency Manager?

Maybe in your mind a question arises “Why should I use composer”. Based on the explanation above, this question may have been answered.

a programmer or web developer is highly recommended to use a dependency manager to make it easier to work on projects. The PHP community or users of the PHP programming language today mostly work with the Laravel, Silex, Phalcon or Symfony2 frameworks.


time you create a new module, you also have a new version. The more bundles and versions there will be a problem. In this case dependencies are the solution to the problem.

If you have a project with a large number of dependencies and there are

  • some of them depend on other bundles,
  • or you want to choose which package is required for the project you are working on,
