- $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.
