Answer 2

Please Note:

The result of filesize() function are cached! Use clearstatcache() to clear the cache...

Answer 3

 echo filesize($_SERVER['DOCUMENT_ROOT']."/images/full-1091.jpg");

note that http://site.com/images/full-1091.jpg is not a file

as for the formatted output ("156,8 Kbytes" or "20,1 Mbytes") try to help yourself and use search. There is a ton of answers to this question already.

Answer 4

Use filesize function like this:

echo filesize($filename) . ' bytes';

You can also format the unit of the size with this function:

function format_size($size) {
      $sizes = array(" Bytes", " KB", " MB", " GB", " TB", " PB", " EB", " ZB", " YB");
      if ($size == 0) { return('n/a'); } else {
      return (round($size/pow(1024, ($i = floor(log($size, 1024)))), 2) . $sizes[$i]); }
}

Answer 5

Images and script hosted on the same account (one site).

Then don't use a URL: Use the direct file path and filesize().
