XZ Utils (wrapper)

User-friendly wrapper for XZ Utils, providing simplified and streamlined access to powerful data compression and decompression tools. For ease of use, you can use the approach known from the compression extensions:

$encoded = xzencode(b'data') or throw new Exception();
$decoded = xzdecode($encoded) or throw new Exception();

printf('`%s` was decoded from encoded base64(`%s`)', $decoded, base64_encode($encoded));

Object-based approach

All functionality is available object-wise through the classes Lzma and Xz.

$xz = new PetrKnap\XzUtils\Xz();
$compressed = $xz->compress(b'data');
$decompressed = $xz->decompress($compressed);

printf('`%s` was decompressed from compressed base64(`%s`)', $decompressed, base64_encode($compressed));

Filter-based approach

For more complex use cases, a filter-based approach is also possible.

use PetrKnap\ExternalFilter\Filter;
use PetrKnap\XzUtils\FilterFactory;

$file = fopen('README.md', 'r');
$xzFile = tmpfile();

# compress file to file
FilterFactory::xz()->compress()->filter(input: $file, output: $xzFile);

fclose($file);
rewind($xzFile);

# decompress file, filter headline and print it
print FilterFactory::xz()->decompress()->pipe(new Filter('head', ['-n', '1']))->filter($xzFile);

fclose($xzFile);
