### How to Install Composer ### Installing Composer
Composer is a single file called `composer.phar`, which is a PHP binary archive. It can either be installed locally in each of your project directories or in a single global location that is in your `$PATH` environment variable. The global method is recommended because it enables you to run it from your current working directory with the command `composer`. So when you come across documentation that states to run Composer as `php composer.phar install`, you can substitute that with:
You can install Composer locally (in your current working directory; though this is no longer recommended) or globally (e.g. /usr/local/bin). Let's assume you want to install Composer locally. From your project's root directory:
curl -s https://getcomposer.org/installer | php
This will download `composer.phar` (a PHP binary archive). You can run this with `php` to manage your project dependencies. <strong>Please Note:</strong> If you pipe downloaded code directly into an interpreter, please read the code online first to confirm it is safe.
### How to Install Composer (manually)
Manually installing Composer is an advanced technique; however, there are various reasons why a developer might prefer this method vs. using the interactive installation routine. The interactive installation checks your PHP installation to ensure that:
- a sufficient version of PHP is being used
- `.phar` files can be executed correctly
- certain directory permissions are sufficient
- certain problematic extensions are not loaded
- certain `php.ini` settings are set
Since a manual installation performs none of these checks, you have to decide whether the trade-off is worth it for you. As such, below is how to obtain Composer manually:
curl -s https://getcomposer.org/composer.phar -o $HOME/local/bin/composer
chmod +x $HOME/local/bin/composer
The path `$HOME/local/bin` (or a directory of your choice) should be in your `$PATH` environment variable. This will result in a `composer` command being available.
When you come across documentation that states to run Composer as `php composer.phar install`, you can substitute that with:
composer install composer install
This section will assume you have installed composer globally. Detailed [installation instructions][5] can be found in the Composer documentation. For Windows users the easiest way to get up and running is to use the [ComposerSetup][6] installer. This section will assume you have installed Composer globally.
