php: remote file size without downloading file

i want find size of file php when user enters link of file uploaded on different site. how?

i assume want size of remote file. following php code should trick:

<?php      // url file (link)     $file = 'http://example.com/file.zip';      $ch = curl_init($file);     curl_setopt($ch, curlopt_nobody, true);     curl_setopt($ch, curlopt_returntransfer, true);     curl_setopt($ch, curlopt_header, true);     curl_setopt($ch, curlopt_followlocation, true);      $data = curl_exec($ch);     curl_close($ch);      if (preg_match('/content-length: (\d+)/', $data, $matches)) {          // contains file size in bytes         $contentlength = (int)$matches[1];      } ?>

you first need obtain url file which, in relation mediafire , other file sharing websites, need code obtain after satisfying free user waiting period.
