Composer - Dependency Management for PHP

Composer helps you declare, manage and install dependencies of PHP projects, ensuring you have the right stack everywhere.

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

Installation / Usage

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 documentation.

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

3. Run Composer: php composer.phar install

4. Browse for more packages on Packagist.

Installation from Source

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

Global installation of Composer (manual)

Follow instructions in the documentation

Updating Composer

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