Composer - Package Management for PHP ===================================== Composer is a package manager tracking local dependencies of your projects and libraries. See [http://getcomposer.org/](http://getcomposer.org/) for more information and documentation. [![Build Status](https://secure.travis-ci.org/composer/composer.png)](http://travis-ci.org/composer/composer) Installation / Usage -------------------- 1. Download the [`composer.phar`](http://getcomposer.org/composer.phar) executable or use the installer. ``` sh $ curl -s http://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](http://packagist.org/about). ``` json { "require": { "monolog/monolog": ">=1.0.0" } } ``` 3. Run Composer: `php composer.phar install` 4. Browse for more packages on [Packagist](http://packagist.org). 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`](http://getcomposer.org/composer.phar) executable 3. Run Composer to get the dependencies: `php composer.phar install` Global installation of Composer (manual) ---------------------------------------- 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 -s http://getcomposer.org/installer | php` 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` 6. Optionally you can rename the composer.phar to composer to make it easier Global installation of Composer (via homebrew) ---------------------------------------------- Installing via this homebrew formula will always get you the latest Composer version. 1. run `brew uninstall composer ; brew install --HEAD https://raw.github.com/gist/1574469/composer.rb` 2. Change into a project directory `cd /path/to/my/project` 3. Use Composer as you normally would `composer.phar install` *You will see a warning "Warning: Cannot verify package integrity"; however, this is benign and expected.* Updating Composer ----------------- Running `php composer.phar self-update` or equivalent will update a phar install with the latest version.
