(PHP Extension) Gzip Compress In Memory and Base64 EncodeDemonstrates how to Gzip compress in-memory data and then encode the compressed data to base64.
<?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. $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"; ?> |
