Better support for PHP

Can you add better support for PHP?

---

This should include better composer.json handling.

The current version only links normal dependencies. But it should also link extension dependencies (ext-*) to correct documentation page on PHP documentation website. Suggested dependencies in suggest section should also be linked correctly.

It should also link name field to package on Packagist (but don’t then forget to fix #45), autoload and autoload-dev sections to correct directories and bin section to correct file.

Composer’s composer.json file is similar to Node’s package.json so you could take some code from there. You should also look to composer.json schema for reference.

---

There should also be parsing of PHP files.

First, it should link require, require_once, include and include_once to correct files. This is similar to Node, except that it can be used with or without brackets.

It should also link use statements. This is a bit different because it includes namespace instead of the file. But with autoloading, program then includes correct file. In this case, this extension should somehow “extract” correct file from namespace and link it.

Oh, there are third-party dependencies imported in the same manner? Great, what a mess!

When you parse composer.json and autoloader it’s not such mess 😁

Anyway, I found an easy solution that works for most cases without parsing composer.json. It still removes the first part of namespace if not found, but also checks if current file namespace is included in a required namespace. This probably means that both namespaces are in the local project.

This should work for most projects, but it still doesn’t support third-party dependencies. To support them, the program would need to use some external API which would parse all project files.

I created PR #52.

@fiatjaf Ok, I can do this. I’ve already started doing this and I will ask you if I will need some guidance or help.

For composer.json, I will probably take some code from package.json parser. And for require, I will also take some things from Node. For use, it could maybe use some external API which would convert namespaces to packages. But I will see if I can do something like this.
