PHP version requirement in `composer.json`

[maks-rafalko]

composer.json says >=7.1 and being on this PHP version I get:

Problem 1
    - doctrine/mongodb-odm 2.0.0-RC2 requires php ^7.2 -> your PHP version (7.1.22) does not satisfy that requirement.
    - doctrine/mongodb-odm 2.0.0-RC1 requires php ^7.2 -> your PHP version (7.1.22) does not satisfy that requirement.
    - Installation request for doctrine/mongodb-odm ^2.0@rc -> satisfiable by doctrine/mongodb-odm[2.0.0-RC1, 2.0.0-RC2].

Thought this is a require-dev package, should PHP version be increased to ^7.2?

I don't think so because MongoDB is optional. Having PHP >= 7.2 is only when you use it.

What is "optional MongoDB" could you please define it? It's required (it is placed under require-dev) package and composer install fails with the error message above.

What I want to say is when I on PHP 7.1 then I can't use api-platform-core.

Probably, instead of removing MongoDB package on 7.1 we need to install for >=7.2?

The packages in require-dev are there when you want to contribute to API Platform. They are not used when you want to use API Platform.
So yes, if you want to contribute to API Platform, you need to have PHP >= 7.2 (or to ignore the platform requirements in Composer).

This is strange :) Developing a lib on 7.2 for target version 7.1. Something that is not covered by tests potentially may be broken.

But if you guys happy with it, it's ok.

Closing.. Thanks for the feedback.
