Requirements

Latest Composer

PHP 7.2.5 or above for the latest version.

Composer 2.2 LTS (Long Term Support)

PHP versions 5.3.2 - 8.1 are still supported via the LTS releases of Composer (2.2.x). If you
run the installer or the self-update command the appropriate Composer version for your PHP
should be automatically selected.

Binary dependencies

7z (or 7zz)
unzip (if 7z is missing)
gzip
tar
unrar
xz
Git (git)
Mercurial (hg)
Fossil (fossil)
Perforce (p4)
Subversion (svn)

It's important to note that the need for these binary dependencies may vary
depending on individual use cases. However, for most users, only 2 dependencies
are essential for Composer: 7z (or 7zz or unzip), and git.
