Where do I need to put file composer.json for composer to work with Symfony
composer-php, php, symfony
Solution
In the root of your project. Because you mentioned symfony, just have a look at the `composer.json` from the symfony-standard edition
https://github.com/symfony/symfony-standard/
Or even better: Follow the official instructions and use symfony-standard as starting point for your project directly.
Start by visiting the Symfony2 download page at http://symfony.com/download. On this page, you'll see the Symfony Standard Edition, which is the main Symfony2 distribution.
You can forkt it directly from github.
Problem
I have installed composer from this link, but I still could not find where do I need to place the `composer.json` file.
