I am trying to connect my server through PHP script as below. But i am unable to reach my server and getting error.

If i connect my server through ftp software with FTPES protocol my server is getting connect

I am getting an Error as

"Warning: ftp_connect() [function.ftp-connect]: php_network_getaddresses: getaddrinfo failed: No such host is known. in C:\xampp\htdocs\uploadftp.php on line 13
Cannot connect to host

Please can any one provide me good solution to solve my issue

// FTP access parameters
$host = '';
$usr = 'user';
$pwd = 'pass';

// file to move:
$local_file = 'localpath/filename.pdf';
$ftp_path = $host.'/foldername/filename.pdf';
// connect to FTP server (port 21)
$conn_id = ftp_connect($host, 21) or die ("Cannot connect to host");
echo $conn_id;
// send access parameters
ftp_login($conn_id, $usr, $pwd) or die("Cannot login");
// turn on passive mode transfers (some servers need this)
ftp_pasv ($conn_id, true);
// perform file upload
$upload = ftp_put($conn_id, $ftp_path, $local_file, FTP_ASCII);
// check upload status:
print (!$upload) ? 'Cannot upload' : 'Upload complete';
print "\n";
** Chmod the file (just as example)
// If you are using PHP4 then you need to use this code:
// (because the "ftp_chmod" command is just available in PHP5+)
if (!function_exists('ftp_chmod')) {
   function ftp_chmod($ftp_stream, $mode, $filename){
        return ftp_site($ftp_stream, sprintf('CHMOD %o %s', $mode, $filename));
// try to chmod the new file to 666 (writeable)
if (ftp_chmod($conn_id, 0666, $ftp_path) !== false) {
    print $ftp_path . " chmoded successfully to 666\n";
} else {
    print "could not chmod $file\n";
// close the FTP stream


I advice you to have a deep look into your code or in the internet. This problem could be caused by anything. You could have a typing error, or try to connect to a computer without ftp-server, or your extension doesn't work or your firewall, router...

What about connecting to that computer via a ftp-client?


i have explained the thing in the above post itself.

Hi rpv_sen,

I'm sorry to say, but in my point of view, you haven't.

Not getting access to a FTP-server does not necessary be a fault of PHP.

For some good advice, we actually need more details.
1) The correct server address
2) does it work with file-zilla
3) what about your firewall?
4) anything installed correctly

As I said before, this problem can be caused by almost anything thinkable.



Thanks for your reply,

I am able to connect my FTP through file-zilla, that to i have specify the protocol as below


we don't have any firewall system.
