Composer is a tool used by PHP to manage dependency relationships. You can declare the external libraries (libraries) you depend on in your project, and Composer will install these dependent library files for you.

Composer can run on Windows, Linux and OSX platforms.

composer resolves project dependencies and implements automatic loading. Developers only need a few command lines to obtain other developers' packages, so PHP development work becomes like stacking blocks, and the combined code can be quickly and easily disassembled according to business needs.

Running Composer requires PHP 5.3.2 or above. Some sensitive PHP settings and compilation flags are also required, but the installer will throw a warning for any incompatibilities.

We will install directly from the source of the package, rather than simply downloading the zip file, you will need git , svn or hg , depending on the version management system you are loading the package into.

It involves "packages" and "libraries", but it is managed on a per-project basis, installing in a directory within your project (e.g. vendor). By default it won't install anything globally. So this is just a dependency management.
