Syntax:
ftp_mdtm( $ftp_connection, $file )
Parameter: This function accepts two parameters as mentioned above and described below:
- $ftp_connection: It is required parameter. It specifies the already existing FTP connection.
- $file: It is required parameter. It specifies the file or path of the file in remote server i.e. FTP server whose last modified will be retrieved.
Return Value: It returns last modified time as a UNIX timestamp on success or -1 on error.
Note:
- This function is available for PHP 4.0.0 and newer version.

PHP
<?php // Connect to FTP server // Use a correct ftp server $ftp_server = "localhost" ;
// Use correct ftp username $ftp_username = "user" ;
// Use correct ftp password corresponding // to the ftp username $ftp_userpass = "user" ;
// File name or path to upload to ftp server $file = "demo_test.txt" ;
// Establishing ftp connection $ftp_connection = ftp_connect( $ftp_server )
or die ( "Could not connect to $ftp_server" );
if ( $ftp_connection ) {
echo "successfully connected to the ftp server!" ;
// Logging in to established connection with
// ftp username password
$login = ftp_login( $ftp_connection , $ftp_username , $ftp_userpass );
if ( $login ) {
// Checking whether logged in successfully or not
echo "<br>logged in successfully!" ;
// Storing last modified data in $last_mod
$last_mod = ftp_mdtm( $ftp_connection , $file );
if ( $last_mod != -1) {
// Checking whether any error occurred or not
// while retrieving last modified data
echo "<br> $file was modified on " .
date ( "F d Y H:i:s." , $last_mod ). "." ;
}
else {
echo "<br>could not get last modified." ;
