Is it possible to upload a file to the FTP server using PHP script while the same script is downloading the meant file from somewhere else? So at the time script is downloading it should upload the file in real-time.

Easy as cake, in theory. First, see FTP function here: http://www.php.net/manual/en/function.ftp-fput.php. Then we use FOPEN wrappers ( http://www.php.net/manual/en/wrappers.php ) to open the file we want to read, and send it over.
To modify the php.net example:
<?php // open some file for reading $file = 'somefile.txt'; $fp = fopen('ftp://user:pass@domain.com/' . $file, 'r'); // 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); // try to upload $file if (ftp_fput($conn_id, $file, $fp, FTP_ASCII)) { echo "Successfully uploaded $file "; } else { echo "There was a problem while uploading $file "; } // close the connection and the file handler ftp_close($conn_id); fclose($fp); ?>
Oh, and you might want non-blocking sometimes: http://www.php.net/manual/en/function.ftp-nb-fput.php
