<?php
// Let's capture all data that was passed to this script, and
// serialize it into a text string:
$ized = serialize($_REQUEST);

// Now prepare this to be written to a gzipped file - Highest Compression:
$compressed = gzencode($ized, 9);

// Generate a guaranteed unique file using tempnam, with a GZ- prefix
$filename = tempnam('.', 'GZ-');

// Now write the compressed file!
file_put_contents($filename, $compressed);
?>
