Install & use Composer for dynamic PHP version

Question

On my local machine I have MAMP PRO running, which allows the change of PHP version per project independently.

Composer is installed on a specific PHP version, but my project aren't.

How would I use composer so that it will either use the PHP version of the local environment, or so that I can easily tell Composer that I am using PHP "x.x.x".

Thank you in advance!

I believe you're looking for this thing: https://getcomposer.org/doc/06-config.md#platform

{
    "config": {
        "platform": {
            //"php": "/path/to/php or php version"
            "php": "7.0.3"
        }
    }
}
