okay then what about this?
function real_filesize_linux($file) {
@exec("filesize $file",$out,$ret);
if ( $ret <> '0' ) return FALSE;
else return($out[0]);
}
if you want it on a remote machine, you should use something like
ssh2_exec() instead of exec()
hope that helps

He was interested on using it over HTTP, not over SSH...
I don't know if there are faster ways, but you could open a socket to the
host on port 80, get the file, and only read the header where it says
content-length: 400 for example, then you know the file is 400bytes when you
download it.
something like:
$socket = fsockopen($host,$port);
$size = 0;
while($size == 0)
{
$line = fgets($socket);
if(strlen($line) >= 17)
{
if(substr(strtolower($line),0,14) == "content-length")
{
$size = substr($line,16)
}
}
Now your remote file size is in $size.
It is not too fast, but everything in PHP is fast and so is this.
