Symfony version(s) affected

7.x.x

Description

Glob pattern **/*.txt will match path file.txt as well as foo/file.txt and so on.

However, Glob::toRegex('**/*.txt') generates regex which fails to match file.txt (it will match foo/file.txt).

Neither class Symfony\Component\Finder\Glob or its method toRegex() are not marked as @internal which encourages us to use it outside of symfony/finder context.

How to reproduce

Reproduction is trivial, use Glob::toRegex(**/*.txt) to generate regex and match that regex against file.txt. Matching should be positive.

Possible Solution

Unfortunately, I am unless here as I do not master regex/globs. It seams that function is port of Perl function, so maybe they fixed already, and that fix is not reflected in PHP port.

Additional Context

I honestly hope that you will keep this function as not internal :)

I believe that every version of symfony/finder is affected with the issue.

Thanks!
