// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Gzip')
$gzip = new COM("Chilkat.Gzip");

$gzipBase64 = 'H4sIAAAAAAAE ... X6aZjXO3EwAA';

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.BinData')

$success = $bd->AppendEncoded($gzipBase64,'base64');

$success = $gzip->UncompressBd($bd);
