This line tells you what your error is:

laravel/framework v5.1.8 requires php >=5.5.9 -> your PHP version (5.5.6) or "config.platform.php" value does not satisfy that requirement.

It says that some of the packages you are trying to install require PHP version 5.5.9 or greater and you are using version 5.5.6

You need to update to a newer version of PHP.

you can try to force it using

composer install --ignore-platform-reqs

but it'll install code without checking php version - really not recomended (code may not work ) , butter upgrade php version
