(PHP Extension) Compress Bytes to Base64 (or any other encoding)

Compresses bytes to base64 or any other encoding. Also decompress to return the original.

Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.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.
$binData = new CkBinData();

for ($i = 1; $i <= 16; $i++) {
    $binData->AppendEncoded('000102030405060708090A0B0C0D0E0F','hex');
}

$compress = new CkCompression();
$compress->put_Algorithm('deflate');
$compress->put_EncodingMode('base64');

$uncompressedBytes = new CkByteData();
$success = $binData->GetBinary($uncompressedBytes);

// Compress and return the compressed bytes in base64 format.
$compressedBase64 = $compress->compressBytesENC($uncompressedBytes);
print 'compressed and base64 encoded: ' . $compressedBase64 . "\n";

// Compress and return in hex format:
$compress->put_EncodingMode('hex');
$compressedHex = $compress->compressBytesENC($uncompressedBytes);
print 'compressed and hex encoded: ' . $compressedHex . "\n";

// Now decompress..
$binData2 = new CkBinData();

// Decompress the base64..
$compress->put_EncodingMode('base64');
$success = $compress->DecompressBytesENC($compressedBase64,$uncompressedBytes);
$binData2->AppendBinary($uncompressedBytes);
// Show the uncompressed bytes in hex format:
print $binData2->getEncoded('hex') . "\n";
print '--' . "\n";

// Decompress the hex..
$compress->put_EncodingMode('hex');
$success = $compress->DecompressBytesENC($compressedHex,$uncompressedBytes);
$binData2->Clear();
$binData2->AppendBinary($uncompressedBytes);
// Show the uncompressed bytes in hex format:
print $binData2->getEncoded('hex') . "\n";
print '--' . "\n";
