Composer `php` constraints with `,` are not supported

[boesing]

Bug Report

Q	A
Version(s)	1.11.5

Summary

When a component uses a more complex constraint which contains ,, the matrix is not able to infer supported PHP versions anymore.

Current behavior

Supported PHP versions are not detected at all.

How to reproduce

composer.json

{
    "require": {
        "php": ">=5.6,<=8.1.99"
    }
}

Expected behavior

All versions between PHP 5.6 and 8.1.99 are detected. As of writing this issue, this would be:

• 5.6
• 7.0
• 7.1
• 7.2
• 7.3
• 7.4
• 8.0
• 8.1

Would a better way not be to just replace , with || or a space?

@internalsystemerror , means AND, while || means OR 🤔

@Ocramius I've just been reviewing the semver guide on npm https://www.npmjs.com/package/semver and I believe , -> (space) would be the only transformation necessary
