I'm having trouble using PHP to SFTP upload files to a remote server. When I use cURL, I'm getting the error described here:

SFTP from PHP - undefined constant CURLOPT_PROTOCOLS and CURLPROTO_SFTP?

I also tried phpseclib as suggested in:

SFTP from within PHP

But when i try phpseclib, i get these errors:

Warning: require_once(Math/BigInteger.php) [function.require-once]: failed to open stream: No such file or directory in /home/john/public_html/test/Net/SSH2.php on line 53

Fatal error: require_once() [function.require]: Failed opening required 'Math/BigInteger.php' (include_path='.:/usr/share/php:/usr/share/pear') in /home/john/public_html/test/Net/SSH2.php on line 53

I then tried using system commands in php like so, but nothing happened:

I also tried

but my php server says ss2_connect is not defined.

I tried to do the following from terminal

scp file.csv 
password

But the server does not allow scp command. I do not have shell access to create ssh keys.

All i can do right now is sftp from terminal and manually upload. But I really want to automate this so a PHP website can do all this.

There aren't many tutorials on how to SFTP upload from PHP. Is it because it's a bad thing to do? If so, what should I be doing? The server I want to upload to only allows sftp connections.

I'm curious how to upload file through FTP using PHP. Let's say I have upload form and user have uploaded a file. How to transfer the file (without moving from temp directory) to some FTP host using PHP?

Here you go:

$ftp = ftp_connect($host, $port, $timeout);
ftp_login($ftp, $user, $pass);
 
$ret = ftp_nb_put($ftp, $dest_file, $source_file, FTP_BINARY, FTP_AUTORESUME);

while (FTP_MOREDATA == $ret)
    {
        // display progress bar, or something
        $ret = ftp_nb_continue($ftp);
    }
 
// all done :-)

Error handling omitted for brevity.

Please note: you have to have ext-ftp installed and enabled.

Here is a code sample

 $ftp_server="";
 $ftp_user_name="";
 $ftp_user_pass="";
 $file = "";//tobe uploaded
 $remote_file = "";

 // 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);

 // upload a file
 if (ftp_put($conn_id, $remote_file, $file, FTP_ASCII)) {
    echo "successfully uploaded $file\n";
    exit;
 } else {
    echo "There was a problem while uploading $file\n";
    exit;
    }
 // close the connection
 ftp_close($conn_id);

How about FTP upload via Curl? (Note: you can also use curl for SFTP, FTPS)

Here's a function to do it for you.

function uploadFTP($server, $username, $password, $local_file, $remote_file){
    // connect to server
    $connection = ftp_connect($server);

    // login
    if (@ftp_login($connection, $username, $password)){
        // successfully connected
    }else{
        return false;
    }

    ftp_put($connection, $remote_file, $local_file, FTP_BINARY);
    ftp_close($connection);
    return true;
}

Usage:

uploadFTP("127.0.0.1", "admin", "mydog123", "C:\\report.txt", "meeting/tuesday/report.txt");

For anyone want to show a the upload progress while doing file transfers, this is a great library php-ftp-client to start :

The code

$interval = 1;
$ftp->asyncDownload('illustrations/assets.zip', 'assets.zip', function ($stat) use ($interval) {
    ob_end_clean();
    ob_start();

    echo sprintf(
        "speed : %s KB/%ss | percentage : %s%% | transferred : %s KB | second now : %s 
",
        $stat['speed'],
        $interval,
        $stat['percentage'],
        $stat['transferred'],
        $stat['seconds']
    );

    ob_flush();
    flush();
}, true, $interval);

Result in the browser :

FTP password must be in single quote otherwise it will not accept special characters

$ftp_server="";
$ftp_user_name="";
$ftp_user_pass=''; // this is the right way 
$file = "";//tobe uploaded
$remote_file = "";
