(PHP ActiveX) Compress Bytes to Base64 (or any other encoding)Compresses bytes to base64 or any other encoding. Also decompress to return the original.
<?php // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // First create some binary data to compress. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.BinData') $binData = new COM("Chilkat.BinData"); for ($i = 1; $i <= 16; $i++) { $binData->AppendEncoded('000102030405060708090A0B0C0D0E0F','hex'); } // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Compression') $compress = new COM("Chilkat.Compression"); $compress->Algorithm = 'deflate'; $compress->EncodingMode = 'base64'; $uncompressedBytes = $binData->GetBinary(); // Compress and return the compressed bytes in base64 format. $compressedBase64 = $compress->compressBytesENC($uncompressedBytes); print 'compressed and base64 encoded: ' . $compressedBase64 .
