ftp_raw — Sends an arbitrary command to an FTP server
Sends an arbitrary command to the FTP server.
Returns the server's response as an array of strings, or null on failure.
No parsing is performed on the response string, nor does
ftp_raw() determine if the command succeeded.
| Version | Description |
|---|---|
| 8.1.0 |
The ftp parameter expects an FTP\Connection
instance now; previously, a resource was expected.
|
Example #1 Using ftp_raw() to login to an FTP server manually.
<?php
$ftp = ftp_connect("ftp.example.com");
/* This is the same as:
ftp_login($ftp, "joeblow", "secret"); */
ftp_raw($ftp, "USER joeblow");
ftp_raw($ftp, "PASS secret");
?><?
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.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));
?>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);
}
?>
