Examples

Here's a quick example proving php-xz works as advertised:

compress.php

<?php
$fh = fopen("php://stdin", "r");
$xz = xzopen("php://stdout", "w");
while (!feof($fh)) {
  xzwrite($xz, fread($fh, 1024));
}
fclose($fh);
xzclose($xz);
?>

decompress.php

<?php
$xz = xzopen("php://stdin", "r");
$fh = fopen("php://stdout", "w");
while (!feof($xz)) {
  fwrite($fh, xzread($xz, 1024));
}
xzclose($xz);
fclose($fh);
?>
