Composer is a dependency manager tracking local dependencies of your projects and libraries.

See https://getcomposer.org/ for more information and documentation.

1. Download the composer.phar executable or use the installer.

   $ curl -sS https://getcomposer.org/installer | php

2. Create a composer.json defining your dependencies. Note that this example is a short version for applications that are not meant to be published as packages themselves. To create libraries/packages please read the guidelines.

   {
       "require": {
           "monolog/monolog": ">=1.0.0"
       }
   }

3. Run Composer: php composer.phar install

4. Browse for more packages on Packagist.

To run tests, or develop Composer itself, you must use the sources and not the phar file as described above.

1. Run git clone https://github.com/composer/composer.git
2. Download the composer.phar executable
3. Run Composer to get the dependencies: cd composer && php ../composer.phar install

You can now run Composer by executing the bin/composer script: php /path/to/composer/bin/composer

Since Composer works with the current working directory it is possible to install it in a system wide way.

1. Change into a directory in your path like cd /usr/local/bin
2. Get Composer curl -sS https://getcomposer.org/installer | php
3. Make the phar executable chmod a+x composer.phar
4. Change into a project directory cd /path/to/my/project
5. Use Composer as you normally would composer.phar install
6. Optionally you can rename the composer.phar to composer to make it easier

Composer is part of the homebrew-php project.

1. Tap the homebrew-php repository into your brew installation if you haven't done yet: brew tap josegonzalez/homebrew-php
2. Run brew install josegonzalez/php/composer.
3. Use Composer with the composer command.

Running php composer.phar self-update or equivalent will update a phar install with the latest version.
