Compress a String and Save as a Gzip File

See more Gzip Examples

This example demonstrates how to use the CompressStringToFile method to compress a string and write the result directly to a Gzip (.gz) file.

The input string is first converted to its byte representation using the specified character set (in this case, UTF-8). The resulting bytes are then compressed using the Gzip format, and the compressed output is written directly to the specified file.

This method is convenient when you want to generate a compressed file from in-memory text without needing intermediate objects such as BinData or StringBuilder.

$gzip = new COM("Chilkat.Gzip");

// The string to be compressed:
$inputStr = 'The quick brown fox jumps over the lazy dog.';

// Compress the string using UTF-8 and write to a file:
$success = $gzip->CompressStringToFile($inputStr,'utf-8','output.gz');
if ($success == 0) {
    print $gzip->LastErrorText . "\n";
    exit;
}

print 'Compression successful.' . "\n";
print 'Gzip file written to output.gz' . "\n";
