See more Gzip Examples

Demonstrates how to Gzip compress in-memory data and then encode the compressed data to base64. PHP Extension

<?php

include("chilkat.php");

$success = false;

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

$gzip = new CkGzip();

// This example will load a file into the fileData object.
// Your application might load fileData from other sources..
$fileData = new CkBinData();
$success = $fileData->LoadFile('qa_data/xml/hamlet.xml');
if ($success != true) {
    print 'Failed to load file.' . "\n";
    exit;
}

// In-place compress the contents of fileData
$success = $gzip->CompressBd($fileData);
if ($success != true) {
    print $gzip->lastErrorText() . "\n";
    exit;
}

// Get the base64 encoded compressed data (in a single line).
$strBase64 = $fileData->getEncoded('base64');
print $strBase64 . "\n";
print '--------' . "\n";

// To get the base64 in multiple lines, as it might appear in MIME,
// use "base64-mime".
$strBase64MultiLine = $fileData->getEncoded('base64-mime');
print $strBase64MultiLine . "\n";
