Answer 1

I ran into the same problem trying to use Symfony 3 on a Bluehost, shared hosting, server. I first had to find and use the php 5.4 client in order to get composer to run, then I got the same error you did. Check the docs here.

PHP needs to be a minimum version of PHP 5.5.9

So you are using a php client that composer supports, and Symfony does not. Bluehost provides the php client v5.6.24 accessible at /usr/php/56/bin/php.

So, using that php executable:

/usr/php/56/bin/php ~/my/path/to/composer.phar install

I successfully ran "composer install" and all of the post-install-cmd's completed with no errors. This is also the way to call bin/console or in your case app/console commands. i.e.

## Symfony 2
/usr/php/56/bin/php app/console cache:clear -e prod

## Symfony 3
/usr/php/56/bin/php bin/console cache:clear -e prod
