Composer
Dependency Manager for PHP
Installation
To quickly install Composer in the current directory, run the following script in your terminal.
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === '55ce33d7678c5a611085589f1f3ddf8b3c52d662cd01d4ba75c0ee0459970c2200a51f492d557530c71c15d8dba01eae') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"
You can place the Composer PHAR anywhere you wish. If you put it in a directory that is part of your PATH, you can access it globally.
sudo mv composer.phar /usr/local/bin/composer
Test usage with a new terminal:
composer -V

Usage
The install command reads the composer.json file from the current directory, resolves the dependencies, and installs them into vendor.
composer install
In order to get the latest versions of the dependencies and to update the composer.lock file.
composer update
The require command adds new packages to the composer.json file from the current directory.
composer require vendor/package vendor/package2
The remove command removes packages from the composer.json file from the current directory.
composer remove vendor/package vendor/package2
The reinstall command looks up installed packages by name, uninstalls them and reinstalls them.
composer reinstall vendor/package vendor/package2
The global command allows you to run other commands like install, remove, require or update as if you were running them from the COMPOSER_HOME directory.
composer global require vendor/package
