Heya, pinocchio123. Welcome to Bytes!

A path is simply a string that uses '/' or '\' characters to separate folders. All you need to do is provide the User with a text input so that he can specify the path.

The tricky part is not collecting the path; it is validating the path to make sure that the User did not (accidentally or maliciously) specify an unsafe path.

For example:

$path = $_POST['path'];
 
$excel = new Spreadsheet_Excel_Writer($path . '/hardware.xls');
 

Most of the time, the results of this code are exactly what one would expect, but you should do some extra validation just to be sure:

$basePath = '/path/to/safe/directory';
$subPath  = $_POST['path'];
 
$target = realpath($basePath . '/' . $subPath);
 
/* Check to make sure the User didn't try to move out of the safe path. */
if( strpos($target, $basePath) === false )
{
  throw new Exception("'{$subPath}' is an invalid path!");
}
 
$excel = new Spreadsheet_Excel_Writer($target . '/hardware.xls');
