答

You can easily apply gzip compression with the gzencode function.

<?
header("Content-Disposition: attachment; filename=yourFile.xml.gz");
header("Content-type: application/x-gzip");

echo gzencode($xmlToCompress);

答

If you don't have the gzip module available,

<?php

  system('gzip filename.xml');

?>

答

Something like this?

<?php
 header('Content-type: application/x-gzip');
 header('Content-Disposition: attachment; filename="downloaded.gz"');
 $data = implode("", file('somefile.xml'));
 print( gzencode($data, 9) ); //9 is the level of compression
?>
