Sometimes the remote server will return you the Content-Length in the HTTP header. However, failing that, the way I would do it is:

PHP Code:


			
$szFile = file_get_contents('http://www.google.co.uk/intl/en_uk/images/logo.gif');
echo round(strlen($szFile) / 1024, 2) . 'KB';

This is assuming that all the characters are 1 byte a piece. 2 byte characters, such as Japanese characters, will give a bad reading, but you should be fine.

Needless to say that the Content-Length in the header is the way forward because the file doesn't need to be downloaded first - this is fine though with smallish files.
