Ok here is what I did but it does not do anything.
I verified that is opening the file ok and everything, but it shows nothing.
It doesn't even produce an error. I am sure there is an easier way than
looping twice, but this is how I have it for now.
$Lines = array();
$TempDir = "tempdata";
$DataFromFile = file("$TempDir/$Dat.txt");
while(list(,$oneline) = each($DataFromFile)) {
array_push($Lines, $oneline);
}
$LineCount = 1;
while(list(,$oneline) = each($DataFromFile)) {
$PriorLineCount = $LineCount - 1;
list($OctetsInB,$OctetsOutB,$TimeB) = split("|", $Lines[$LineCount]);
list($OctetsInA,$OctetsOutA,$TimeA) = split("|", $Lines[$PriorLineCount]);
// After much help and work with Harry, this is the formula we came up
with to show data rates over time.
// (((Counter_Now - Counter_Before) / (Time_Now - Time_Before(converted to
seconds))) * 8)) / 1000 = kbits per hour
$kbitsout = ((($OctetsOutB - $OctetsOutA) / ($TimeB - $TimeA)) * 8 ) /
1000;
print "$kbitsout Kbits - $LineCount<br>\n";
$LineCount++;
}
