error

Answer 1

I think you should just need to change if($conn_id) to if($conn_id === FALSE)

EDIT

Try running this:

<?php
$c = ftp_connect('ftp.mozilla.org');
var_dump($c);

$c = ftp_connect('abcdefg');
var_dump($c);
?>

You should get this:

resource(2) of type (FTP Buffer) Warning: ftp_connect()

[function.ftp-connect]: php_network_getaddresses: getaddrinfo failed: No such host is known. in C:\abc\def.php on line 5

bool(false)

Answer 2

try this and you done

$conn = @ftp_connect("ftp.funnybunnyvideos.in");
if($conn)
{
    echo 'server name is valid';
}
else
{
    echo 'server name is invalid';
}

Cheers !!!
