I think this should work:

$ourFileName = $vbulletin->options['thefile'];
if (!file_exists($ourFileName)) {
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fclose($ourFileHandle);
}

but you probably wouldn't want the "or die()" part because that would leave you with a white page with an error message. You could do something like this:

$ourFileName = $vbulletin->options['thefile'];
if (!file_exists($ourFileName)) 
{
   $ourFileHandle = fopen($ourFileName, 'w');
   if ($ourFileHandle === FALSE)
   {
      // Do something here to handle error
   }
   else
   {
      fclose($ourFileHandle);
   }
}

Also, using "w" in the fopen call will truncate the file (make it empty), so if you don't want that, use either "r" or "a".
