and here is in the php file

$fp = fopen($_GET['physical_path'] . '/includes/configure.php', 'w');
fputs($fp, $file_contents);
fclose($fp);
@chmod($_GET['physical_path'] . '/includes/configure.php', 0644);
// now Admin version:
require('includes/admin_configure.php');
$fp = fopen($_GET['physical_path'] . '/admin/includes/configure.php', 'w');
fputs($fp, $file_contents);
fclose($fp);
