Sends an arbitrary command to the FTP server.

参数

<?php
$fp = ftp_connect("ftp.example.com");

/* This is the same as:

ftp_raw($fp, "USER joeblow");
ftp_raw($fp, "PASS secret");
?>

How to realize the possibility of transferring data from one FTP-server to another via FXP?

<?php
// ...

$ansver = ftp_raw($ftp_conn1, 'PASV');

if (intval($ansver[0]) == 227) {
    ftp_raw($ftp_conn2, 'PORT '.substr($ansver[0], $n = strpos($ansver[0], '(') + 1, strpos($m[0], ')', $n) - $n));
    ftp_raw($ftp_conn1, 'STOR '.$filename); // need asynchronously (non-blocking)
    ftp_raw($ftp_conn2, 'RETR '.$filename);
}
?>

Note that the $command can not contains any illegal character such as \n, \r, \t, or this function will return NULL.

Try using the trim() before calling ftp_raw().

<?php
ftp_raw($connid, trim($command));
?>

<?
ftp_raw($ftpconn,"CLNT <client>");
?>

Is a good way to let the ftp-server know which client it's dealing with. Guess this can be useful if you're making a homemade ftp-client. Only do this if the ftp-server has responded to FEAT command with a response including CLNT.
