[Feature request] Add a path_join function

[shyim]

Description

I really miss in PHP a function to join easily paths like the node's path.join or in other languages.
I know it's really easy to implement in the user-land, but It would be nice to have this PHP as this is some base filesystem functionality like realpath, basename which should be included by default (in my opinion).

Usage would be like:

path_join('/base', 'my', 'path'); // /base/my/path
path_join('/base', 'my', 'path', 'test', '..'); // /base/my/path

Why not just string concatenation?

When you concat just the paths you have to think about:

• does the before path end with a /, you have to normalize all parts
• for windows compatibility you have to use DIRECTORY_SEPERATOR

One annoyance I have with these APIs is when I want the path separation behaviour of the platform I'm not running on; i.e. build a Unix path on Windows. It'd be nice to have a way to specify the behaviour (but obviously make using the current platform's easy and default).

I'd add to that path_normalize and path_resolve

// path_normalize(string $path) : string
echo path_normalize('foo\\bar/../baz') // => foo/baz

// path_join(string ...$paths) : string
echo path_join('/root', '/foo\\bar/baz', '../test', 'file.json'); // => /foo/bar/test/file.json
echo path_join('foo\\bar', '..', 'file.json'); // => foo/file.json

// path_resolve(string ...$paths):string => path_join(getcwd(), ...$paths);
echo path_resolve('foo\\bar/../baz/file.json') // => /var/www/foo/baz/file.json

It would be really good to start a discussion about this. I think this would be a nice addition.

@shyim I can only find the karma grant email, but no discussion. Are you planning to work on this? I can offer help as I also think this would be a useful addition.

FWIW I've started a pre-RFC discussion on the mailing list for this: https://externals.io/message/121936
