Hi everyone,
I'm not sure of the correct formula for this, if I have a file - just
for example, that is 10245458756 bytes long and the download speed is
60KB a second, what formula would I use to calculate how many
seconds/minutes/hours it would take to download the file?
Maths really isn't my strong point and formulas go over my head
otherwise I wouldn't ask :-(
Thanks everyone
Chris
$size = 1024548756; // in bytes
$kb_per_sec = 60; // I assume you'll fill these in from elsewhere?
$b_per_sec = $kb_per_sec * 1024;
$seconds = $size / $b_per_sec;
$minutes = 0;
$hours = 0;
if($seconds > 60)
{
// 60 seconds to a minute
$minutes = (int)($seconds / 60);
$seconds -= $minutes * 60;
if($minutes > 60)
{
// 60 minutes to an hour
$hours = (int)($minutes / 60);
$minutes -= $hours * 60;
// if you want to go further and calculate days, have at :)
}
}
You could also approach this using modulus, but if you're not confident
with math, this might be a more intuitive approach.
