Composer is the package manager used by modern PHP applications. Use Composer to manage dependencies in your Symfony applications and to install Symfony Components in your PHP projects.
It’s recommended to install Composer globally in your system as explained in the following sections.
Install Composer on Linux and Mac OS X¶
To install Composer on Linux or Mac OS X, execute the following two commands:
$ curl -sS https://getcomposer.org/installer | php $ sudo mv composer.phar /usr/local/bin/composer
If you don’t have
curl installed, you can also just download the
installer file manually at https://getcomposer.org/installer and
$ php installer $ sudo mv composer.phar /usr/local/bin/composer
Install Composer on Windows¶
Download the installer from getcomposer.org/download, execute it and follow the instructions.
