Re: [PHP] Adding up values
There's really not much to it. The intval of '-' is 0, so it doesn't cause
any problems.
$numbers = file('path/logfile.txt');
$total = 0;
foreach ($numbers as $num) $total += intval($num);

Or use array_sum():
$numbers = file('path/logfile.txt');
$total = array_sum($numbers);
