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
   

   Note: If the above fails for some reason, you can download the installer with php instead:

   php -r "readfile('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.
