kjdev / zstd example snippets


// Using functions
$data = zstd_compress('test');
zstd_uncompress($data);

// Using namespaced functions
$data = \Zstd\compress('test');
\Zstd\uncompress($data);

// Using streams
file_put_contents("compress.zstd:///path/to/data.zstd", $data);
readfile("compress.zstd:///path/to/data.zstd");

// Providing level of compression, when using streams 
$context = stream_context_create([
    'zstd' => [
            'level' => ZSTD_COMPRESS_LEVEL_MIN,
            // 'dict' => $dict,
