Problem with filemtime

I'm running the following script (simplified for discussion) to create a CSV file. My problem here is that the first filemtime and the last filemtime always equal each other. What I am trying to get is the filemtime ($new_last_modified) of the file that was just executed 3 lines earlier. Is there something I need to do differently? I tried putting a sleep(20) after the fclose, but that didn't seem to help. $csv_file = "myFile.csv"; $last_modified_csv = filemtime($csv_file); $fh = fopen($csv_file, 'w') or die("can't open file"); fwrite($fh, "Data Goes Here"); fclose($fh); $new_last_modified = filemtime($csv_file); -- Kevin Murphy Webmaster: Information and Marketing Services Western Nevada College www.wnc.edu 775-445-3326
