Composer - Package Management for PHP

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

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

Installation / Usage

Download the composer.phar executable or use the installer.
```
$ curl -s http://getcomposer.org/installer | php
```
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"
    }
}
```
Run Composer: php composer.phar install
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.

Run git clone https://github.com/composer/composer.git
Download the composer.phar executable
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)

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

Change into a directory in your path like cd /usr/local/bin
Get Composer curl -s http://getcomposer.org/installer | php
Make the phar executeable chmod a+x composer.phar
Change into a project directory cd /path/to/my/project
Use Composer as you normally would composer.phar install
Optionally you can rename the composer.phar to composer to make it easier

Global installation of Composer (via homebrew)

Composer is part of the homebrew-php project.

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

Updating Composer

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