Bypass PHP version, extension requirement, etc.
When trying to install "laravel/framework" : "~5.0" (which is currently Laravel 5.1.*) on a GoDaddy server, i keep ended up installing Laravel 5.0.* because while Godaddy supports PHP-CGI 5.5, they only support PHP-CLI 5.4.* on my server and composer is not working using PHP-CGI.
To bypass requirements check on an enviroment where you sure requirements are already met, use composer with the following switch.
composer install --ignore-platform-reqscomposer dump-autoload
