Calculate download time

I have a script that has the file size as a value say for instance: $filesize

I would like to display the download times for various connections by using the value $filesize.

Do you have a snippet of code for this etc?

Thanks in advance.

 

<?php

function downloadTime( $size_of_file_in_bytes, $download_kilobytes_per_second )
{
    $seconds = $size_of_file_in_bytes / ( $download_kilobytes_per_second * 1024 );
    $minutes = floor( $seconds / 60 );
    $seconds = $seconds % 60;
    return array( 'minutes' => $minutes, 'seconds' => $seconds );
}

list( $minutes, $seconds ) = array_values( downloadTime(10489999, 2048) );
echo $minutes . ' minutes ' . $seconds . ' seconds.';
