FTP and PHP

[shyuanlon]

I am using the code belows to upload a
.TAR file from one server to another server using FTP in linux server :

$ftp_server="FTP.server.com";
$ftp_id = ftp_connect($ftp_server);

$destination_file = "abc.tar";
$tar_file ="abc.tar";

ftp_login($ftp_id,"shon", "shon");
// ready to communicate
ftp_pasv($ftp_id, true); //my ftp server only accept passive mode

$ftp_upload = ftp_put($ftp_id, $destination_file, $tar_file, FTP_BINARY);

if($ftp_upload){
// Successful uploaded get the file size... close connection

$filesize_ftpserver = ftp_size($ftp_id, $destination_file);
echo $filesize_ftpserver;

}else{
echo "There was a problem while uploading ".$filename_ftpserver;
}

The problem is the trasnfer some times succesfully and sometimes not.

but i cannot get to know wat is the problem of the server, is there any way to know wat has happenning

Somthing like when connectiong refuse the sever will able to retrun a msg of " Connection Refuse" how to get those messege? of coz using PHP 🙂)

Thanks GUYS

You can get that information plus a lot more (maybe more than you want 🙂 ) with curl:

define('ASCII', true);
define('BINARY', false);
$server      = 'ftp://ftp.example.com';
$username    = 'username';
$password    = 'password';
$local_path  = '/local/path/';
$remote_path = '/remote/path/';
$local_file  = 'local_file.tar';
$remote_file = 'remote_file.tar';
$trans_mode  = BINARY;

$fp = fopen($file_path . $up_file, 'r');
$ch = curl_init();     

curl_setopt($ch, CURLOPT_INFILE, $fp);  

curl_setopt($ch, CURLOPT_INFILESIZE, filesize($local_path . $local_file));  

curl_setopt($ch, CURLOPT_URL, $server . $remote_path . $remote_file);  

curl_setopt($ch, CURLOPT_USERPWD, $username . ':' . $password);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);  

curl_setopt($ch, CURLOPT_UPLOAD, true);  

curl_setopt($ch, CURLOPT_TRANSFERTEXT, $trans_mode);  

curl_setopt($ch, CURLOPT_HEADERFUNCTION, 'curl_header_read');
$curl       = curl_exec($ch);
$curl_info  = curl_getinfo($ch);
$curl_errno = curl_errno($ch);
$curl_error = curl_error($ch);
curl_close($ch);
fclose($fp);  

$tab = '    ';
echo '<br /><b>curl_exec()</b> = ' . $curl . '<br />';  

echo '<br /><b>curl_errno()</b> = ' . $curl_errno . '<br />';  

If ($curl_error != '') { 
    echo '<br /><b>curl_error()</b> = ' . $curl_error . '<br />';
}  

echo '<br /><b>curl_getinfo()</b> =<br />';
foreach ($curl_info as $key => $value) {
    echo $tab . $key . ' => ' . $value;
    echo '<br />';
}

function curl_header_read($ch, &$str) {
    echo '<i>Server:</i> ' . nl2br($str);
    $len = strlen($str);
    return $len;
}

These codes need curl package ...
but i have tried whole morning still fail to install curl package ,, is there any other way ?

It could also be done using streams, or fsockopen(), or sockets. Any of those, in fact might be better than curl, since with them you can establish a connection and keep it open for multiple uploads/downloads. For a single upload like yours, though, curl is great because it's easy to use and fast (at least fast enough). If you experiment with the ftp functions you may even be able to get them to do what you want.

There are probably a lot of different ftp scripts/routines on the internet. It'd be mostly a matter of finding one that works for you and your server.

edit: Have you thought about using a form-based http upload script? That might be the easiest way of all. You could password-protect the script and use it to upload as many or as few files as you need.
