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 ftpparameter 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");
?>
