如何从.tar存档文件中删除文件夹？

Question

I want to delete a directory from a TAR archive file. I used the PharData class but I don't know how delete a directory.

I tried the Phardata::delete() method, but it only destroys empty folders in the TAR file and cannot delete other folders.

I tried the code below to delete folders from ZIP files and that works well. This code didn't work in PharData objects. How can I do it in the TAR file?

private function deleteArchiveDirectory($directory){
    // When archive object is ZipArchive` 
    if ($this->archiveObject instanceof ZipArchive) { 
        $numFiles = $this->archiveObject->numFiles;   
        $folderToDelete = $directory;  //folder to delete relative to root
        for ($i = 0; $i < $numFiles; $i++) {     
            $entryInfo = $this->archiveObject->statIndex($i);
            if (substr($entryInfo["name"], 0, 
            strlen($folderToDelete)) == $folderToDelete) {
                $this->archiveObject->deleteIndex($i);
            }
        }
    }
    // When archive object is PharData
    if ($this->archiveObject instanceof PharData) {
        // How can I do it enter code here
    }
}
