PHP & FTP:  ftp_connect error - php_network_getaddresses: getaddrinfo failed: No such host is known

Posted on 2006-11-04
Last Modified: 2007-12-19
Hi all,

I'm a PHP noob, so please excuse my ignorance....

I have the following script;

// define some variables
$ftp_server= "ftp://ftp2.bom.gov.au/anon/gen/fwo";
$ftp_user_name= "anonymous";
$ftp_user_pass= "webmaster@aquaticadventures.com.au";
$local_file = "4day.txt";
$server_file = "IDV10450.txt";

// 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);

// check connection
if ((!$conn_id) || (!$login_result)) {
        echo "FTP connection has failed!<br>";
        echo "Attempted to connect to $ftp_server for user $ftp_user_name<br>";
    } else {
        echo "Connected to $ftp_server, for user $ftp_user_name<br>";

// try to download $server_file and save to $local_file
if (ftp_get($conn_id, $local_file, $server_file, FTP_BINARY)) {
   echo "Successfully written to $local_file\n";
} else {
   echo "There was a problem\n";

// close the connection


Which gives the following error;
Warning: ftp_connect() [function.ftp-connect]: php_network_getaddresses: getaddrinfo failed: No such host is known. in D:\Elysian Visions\AA test page\4day.php on line 12

Warning: ftp_login() expects parameter 1 to be resource, boolean given in D:\Elysian Visions\AA test page\4day.php on line 15
FTP connection has failed!
Attempted to connect to ftp://ftp.bom.gov.au for user anonymous

I'm not sure why it won't connect to the FTP server, which is a public server provided by the Bureau of Meteorology (Government), hence the user & password.

Do I have to do something in php.ini to allow FTP via PHP? Or do I need to have an IP address to connect to instead of ftp://ftp2.bom.gov.au/anon/gen/fwo? Or do I have a stupid syntax error I can't seem to spot?

Thanks a million for your help.

The BFG :D

change this:

$ftp_server= "ftp://ftp2.bom.gov.au/anon/gen/fwo";


$ftp_server= "ftp2.bom.gov.au";

and this:

$server_file = "IDV10450.txt";



$server_file = "/anon/gen/fwo/IDV10450.txt";

It worked! You're a chanpion!

Thanks a million.  :D
Can I ask where you got the IP from? Also wondering - does this mean that for $ftp_server you can't use a URL, only an IP addrress?

Again, thanks for your help.

<<Can I ask where you got the IP from?

well i just resolved the domain you posted.

An easy way to do resolve a domain is to ping the domain name with the ping tool wich comes with windows xp and other operating systems as well.

<<Also wondering - does this mean that for $ftp_server you can't use a URL, only an IP addrress?

You can use an ip address or a domain, both works.

If using a domain you must resolve the domain fisrt. To do it in PHP use gethostbyname()

gethostbyname() could be other option to resolve your issue.
