Composer - Package Management for PHP

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

See the about page on packagist.org for more information.

Installation / Usage

1. Download the composer.phar executable

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.

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: php composer.phar install

Global installation of 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 wget http://getcomposer.org/composer.phar
3. Make the phar executeable 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

Configuration

Additional options for composer can be configured in composer.json by using the config section.

{
    "config": {
        "vendor-dir": "custom/path/for/vendor"
    }
}

• vendor-dir: The location to install vendor packages. The location can be supplied as an absolute or relative path but must be within the current working directory.
