Ftp_connect(): php_network_getaddresses: getaddrinfo failed: name or service not known

I was trying to connect with ftp server using ftp_connect() function of PHP as shown below:

But it returns this error:

Warning: ftp_connect() [function.ftp-connect]: php_network_getaddresses: getaddrinfo failed: No such host is known. in D:\wamp\www\ftp2.php on line 6

Although this is a very common type of error, I still cannot find any solution. Can anyone provide some possible solutions?

Thank you for your time.

You must supply only the ftp server hostname, rather than the hostname and directory path, and the irrelevant http:// since this is an FTP connection.

$ftp_server = "ftp.mozilla.org";
$conn_id = ftp_connect($ftp_server) or die("Couldn't connect to $ftp_server"); 

// Then chdir to the correct directory:
ftp_chdir($conn_id, "/pub/mozilla.org");

See the full documentation of PHP's FTP functions.

Get rid of the http://, it is not part of the server address.

I try to use the php ftp_connect fucntion on my dedicated server and I'm unable to establish a connection:

$conn_id = ftp_connect($ftp_server, 21) or die("Unable to connect to $ftp_server") ;

I'm sure the function is available as I test with :

function_exists('ftp_connect')

and it returns true

When I ftp the server through the shell I can reach it so I guess it's not a firewall issue. Am I missing something else ?

Thanks for your precious advices

PHP will log a warning if ftp_connect fails. However, you may have logging disabled or going to an unexpected place. Check your php.ini and related configuration files to ensure that logging is enabled and to specify where the logs are written.

To diagnose this problem without access to logs, try running PHP from the command line. For instance:

$ php

Ctrl+D

PHP Warning:  ftp_connect(): php_network_getaddresses: getaddrinfo failed: Name or service not known in - on line 1

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 …

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

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
etc

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

Greetings
