                                   ftp_mdtm

   (PHP 3>= 3.0.13, PHP 4 )
   ftp_mdtm -- Returns the last modified time of the given file

Description

   int ftp_mdtm ( resource ftp_stream, string remote_file)

   ftp_mdtm() checks the last modified time for a file, and returns it as
   a Unix timestamp. If an error occurs, or the file does not exist, -1
   is returned.

   Returns a Unix timestamp on success, or -1 on error.

   Example 1. ftp_mdtm() example
   <?php
   $file = 'somefile.txt';
   // set up basic connection
   $conn_id = ftp_connect($ftp_server);
   // login with username and password
   $login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
   //  get the last modified time
   $buff = ftp_mdtm($conn_id, $file);
   if ($buff != -1) {
       // somefile.txt was last modified on: March 26 2003 14:16:41.
       echo "$file was last modified on : " . date("F d Y H:i:s.",
   $buff);
   } else {
       echo "Couldn't get mdtime";
   }
   // close the connection
   ftp_close($conn_id);
   ?>

     Note: Not all servers support this feature!

     Note: ftp_mdtm() does not work with directories.
