   (PHP 3, PHP 4 )
   ftell -- Tells file pointer read/write position

   Returns the position of the file pointer referenced by handle; i.e.,
   its offset into the file stream.

   opened by fopen() or popen().

   <?php
   // opens a file and read some data
   $fp = fopen("/etc/passwd", "r");
   $data = fgets($fp, 12);
   // where are we ?
   echo ftell($fp); // 11
   fclose($fp);
   ?>
