Can I define the minimum php version for my module in my .info.yml file? I need to define the minimum PHP version in my module.info.yml file but I don't know if this is posible using:

php: 5.6


If you search about this in the drupal.org documentation you will only see the reference about this in the theme.info.yml file: Defining a theme with an .info.yml file


  php (optional) 
  
  The minimum version of PHP required. Defaults to value
  of DRUPAL_MINIMUM_PHP constant. 
  
  php: 5.5.9


But in the documentation about the module.info.yml file there is nothing about the php version: Let Drupal 8 know about your module with an .info.yml file.

So, really I can't define the minimum php version in my module.info.yml file?
Sometimes the answer to a question is best found by trying. If you add php: 8.0 to your module.info.yml file you will see this:



So it can still be used. (I have updated the linked documentation as well.)
