== TO A SERVER AND THEN TEST IT ==
== IT WOULD BE GOOD IF YOU USE A BINARY FILE THATS MORE THAN 2 MB==

Does this code still work?

Did you attempt to test it for yourself before reviving a nearly 2 year old topic? If so, you made no indication.

I agree 100% with you. I saw the thread was old and was being lazy instead of just testing for myself.

I did not test and should have before asking, I am sorry I am new here and just looking to learn a few things.

In the future I will make sure to try things and then ask better questions.

I just tried it, and it still works. Here the result :

Your Current Bandwidth is:

2048.00 Mbps

That Means You Can Download At 262144 KB/sec. FROM THIS SITE.

It worked for me too!

3321.00 Mbps

If anyone is interested, I fixed some of the calculations and made an updated version of this script, incorporating AJAX for the download speed test:

# most people are used to seeing this information presented incorrectly, I am keeping that #
# tradition. If you prefer to see actual "KB" and "MB" ratings, just alter the $divisor variable #
# below to make the adjustment. #
#################################################################################################### #
$data_file = "dilbert.zip"; // $data_file should be some generic binary file - this script was tested with a 3 MB zip file of some Dilbert comic strips. The file should be sufficiently large so that the latency from the initial HTTP request itself does not skew the results by much.
$filesize = filesize($data_file);
$divisor = 1024; //set this to 1000 instead of 1024 if you want true KB and MB, rather than mis-labeled KiB and MiB that we are most used to seeing...

I am hosting it here for now with a 456KB file to test with (if anyone wants to see the script in action):
http://rowsdower.freehostia.com/php/?page=speed_test

Freehostia won't let me put up a file greater than 500KB in size on their free service so the current file will have to do on that sample page. In your production, however, it would be best to use a larger file (I would guess about 2MB or 3MB for a good balance of accuracy and script performance time).
