<?php
function download_time($file) {
if(!function_exists("sec_format")) {
function sec_format($seconds) {
$units = array( "day|s"=>86400,
"hour|s"=>3600,
"minute|s"=>60,
"second|s"=>1
);
if($seconds < 1) {
return "< 1second";
} else {
$show = FALSE;
$ausg = "";
foreach($units as $key=>$value) {
$t = round($seconds/$value);
$seconds = $seconds%$value;
list($s, $pl) = explode("|", $key);
if($t > 0 || $show) {
if($t == 1) {
$ausg .= $t." ".$s.", ";
} else {
$ausg .= $t." ".$s.$pl.", ";
}
$show = TRUE;
}
}
$ausg = substr($ausg, 0, strlen($ausg)-2);
return $ausg;
}
}
}
$values = array("DSL"=>768,
"ISDN"=>128,
"Modem"=>56.6
);
$size = filesize($file);
$ausg = round($size/(1024), 0)." KB<br />";
$size *= 8;
foreach($values as $key=>$value) {
$time = sec_format($size/($value*1024));
$ausg .= $time." @ ".$value." kBit (".$key.")<br />";
}
return $ausg;
}
echo download_time("test.zip");
?>

Sure that DSL today can be much faster, but don't be lazy and but it to the array  |
