Composer Dependency management tools

Composer is a PHP A dependency management tool , It is managed on a per-project basis, in a directory of your project (e.g. Vendor ) for installation.

By default it will not install anything globally. Therefore, this is only a dependency management.

Composer This will solve the 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).
