Add uploaded:// stream
This adds a new stream wrapper giving direct access to an uplaoded file bypassing open_basedir restrictions.
This is useful if one doesn't want to keep an uplaoded file, but only access the content and tavoids having to use move_uplaoded_file(), which requires a writeable location inside open_basedir.
This can be used like
$fh = fopen($_FILES['some_name']['tmp_uri'], "r");
The file can also be overwritten by using w or a mode. Using stat() on the file is supported as well.
Please mind that "Mentors | @Johannes" does not refer to the GitHub user @johannes, but probably @JohannesMessner. I can encourage you to do great things, but not help with the project. Have fun!
Sorry, I don't know :)
