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.

PharData::extractTo — Extract the contents of a tar/zip archive to a directory
$directory, array|string|null $files = null, bool $overwrite = false): bool
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 parameter files can 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().
directory
Path to extract the given files to
filesThe name of a file or directory to extract, or an array of files/directories to extract
overwrite
Set to true to enable overwriting existing files
returns true on success, but it is better to check for thrown exception,
and assume success if none is thrown.
Throws PharException if errors occur while flushing changes to disk.
Beispiel #1 A PharData::extractTo() example
<?php
try {
$phar = new PharData('myphar.tar');
$phar->extractTo('/full/path'); // extract all files
$phar->extractTo('/another/path', 'file.txt'); // extract only file.txt
$phar->extractTo('/this/path',
array('file1.txt', 'file2.txt')); // extract 2 files only
$phar->extractTo('/third/path', null, true); // extract all files, and overwrite
} catch (Exception $e) {
// handle errors
}
?>Hinweis:
Windows NTFS-Dateisysteme unterstützen einige Zeichen in Dateinamen nicht, nämlich
<|>*?":. Dateinamen mit einem Punkt am Ende werden ebenfalls nicht unterstützt. Im Gegensatz zu einigen Extraktionswerkzeugen ersetzt diese Methode diese Zeichen nicht durch einen Unterstrich, sondern extrahiert solche Dateien nicht.

http://php.net/manual/pl/phar.fileformat.tar.phpI'm unable to extract the first directory from a tar archive:
the destination dir remains empty,
no error is thrown
<?php
$tar = new \PharData('archive.tar');
if ($tar->current()->isDir()) {
echo 'is_dir';
$dir = $tar->current()->getPathname();
$dir = basename($dir);
$tar->extractTo('destination', $dir);
}
?>
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?This is an example of how to decompress and unarchive a TAR.GZ file using Phar decompress() and extractTo() methods:
<?php
echo '<h1>TAR.GZ decompress</h1>';
$file_name = 'your_file.tar.gz';
$tar_file_name = str_replace('.gz', '', $file_name);
$dir_file_name = str_replace('.tar.gz', '', $file_name);
// decompress from gz and creates your_file.tar
$p = new PharData($file_name);
$p->decompress();
// unarchive from the tar to folder 'your_file'
$phar = new PharData($tar_file_name);
$phar->extractTo($dir_file_name);
echo '<h1>DONE</h1>';
?>
