PharData::extractTo()

(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 2.0.0)

Extract the contents of a tar/zip archive to a directory

说明

Extract all files within a tar/zip archive to disk. Extracted files and directories preserve permissions as stored in the archive. The optional parameters allow optional control over which files are extracted, and whether existing files on disk can be overwritten. The second parameterfilescan be either the name of a file or directory to extract, or an array of names of files and directories to extract. By default, this method will not overwrite existing files, the third parameter can be set to true to enable overwriting of files. This method is similar to ZipArchive::extractTo().

• Phar::extractTo() Extract the contents of a phar archive to a directory

I'm unable to extract the first directory from a tar archive:
the destination dir remains empty,
no error is thrown

the docs hint that the second param could be a name of file OR DIR to be extracted from the archive, is that really possible?

Note that PHAR only supports extracting the 'ustar' variant of the tar archives.
Some systems (such as older versions of Mac OS X) generate the 'pax' format by default.
