[RESOLVED] How to get size of file in website

Hello
How can I get size of a file which website?
Example:
http://www.website/file.zip

How can I get size of file.zip?

Thx

filesize()

filesize() doesn't work for files on websites.

Sorry, didn't read carefully enough.

You can't get the size of files on remote websites. Not easily and reliably, anyway

If the response sends a Content-Length header then you can get the size. This is not necessarily the size of the file though, it is the size f the response body.

If there is no Content-Length header, you'll need to download the entire file first.

Could you do it?
Thanks

You can use the stream_get_meta_data() function to get the heads from an fopen wrapper.

PHP Code:

---

      if (!($fp = @fopen($url, 'r'))) {
         /* error here - as url could not be opened */
      }

     $metaData = stream_get_meta_data($fp);
     $size = null;
     foreach ($metaData['wrapper_data'] as $header) {
         if (strpos(strtolower($header), 'content-length') !== false) {
            $size = substr($header, strpos($header, ':') + 1);
            break;
         }
      }

      if (is_null($size)) {
          /* Content-Length header not found */
      }
