Composer is not a package manager. Yes, it involves "packages" and "libraries", but it is managed on a per-project basis and installed in a directory of your project (for example vendor ). By default it will not install anything globally. Therefore, this is only a dependency management.

Composer will solve this problem for you:

A) You have a project that relies on a number of libraries.

b) Some of these libraries depend on other libraries.

c) You declare what you depend on.

d) Composer will find out which version of the package needs to be installed and install them (download them to your project).
