I also got the error message. When I refer the PHP official doc, it seems that the ftp_get can accept the three parameters expect, not 4. Is the official doc wrong? PHP official doc: http://php.net/manual/en/function.ftp-get.php Test script: --------------- <?php // define some variables $local_file = 'local.zip'; $server_file = 'server.zip'; // 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 download $server_file and save to $local_file if (ftp_get($conn_id, $local_file, $server_file)) { echo "Successfully written to $local_file\n"; } else { echo "There was a problem\n"; } // close the connection ftp_close($conn_id); Expected result: ---------------- No error Actual result: -------------- PHP Warning: ftp_get() expects at least 4 parameters, 3 given ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76471&edit=1
