Math Operator Problem?

Hi, I have a snippet of code as follows: while (!feof($fh2)) { $total_time=0; $lines= fgets($fh2); $count= strlen($lines); if ($count == 0) { //There are no lines } else { $total_time += $lines; } } What I am trying to do here is to increment the total_time value and have it display on the screen without changing the actual input file. However, when I tried to output the result on the screen, all I am getting is the same value as I have in the text file originally. Can anyone on the list please give me some insight on what I am doing wrong here? Thanks in advance.
