PharData::extractTo

    (PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 2.0.0)

    PharData::extractTo — Extract the contents of a tar/zip archive to a directory

    Description

    public PharData::extractTo(string $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().

    Parameters

    directory

    Path to extract the given files to

    files

    The 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

    Return Values

    returns true on success, but it is better to check for thrown exception, and assume success if none is thrown.

    Errors/Exceptions

    Throws PharException if errors occur while flushing changes to disk.

    Examples

    Example #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
    }
    ?>

    Notes

    Note:

    Windows NTFS file systems do not support some characters in filenames, namely <|>*?":. Filenames with a trailing dot are not supported either. Contrary to some extraction tools, this method does not replace these characters with an underscore, but instead fails to extract such files.

    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.

    I'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>';
    ?>
