PHP/SSH: Multiple command in the same session (do confirmation)

Question

I've a problem with PHP and the SSH-Extension/Net-SSH-Libary. I use it for sending commands to a NetApp-Filer. So I want to create/delete Volumes on the filer. Creation for Volumes is no problem.

But when I want to delete them, the filer ask's for an confirmation ("Are you sure you want to delete.. y/n") and I can't give the NetApp this information. For every exec-Command ist starts a new session.

Is it possible to run more commands in the same session or give them a confirmation of some commands?

My Code (only Volume delete):

<?php
include('Net/SSH2.php');
            $ssh = new Net_SSH2('172.22.31.53');
            if (!$ssh->login('admin', '12Test')) {
                exit('Login Failed');
            }

            echo $ssh->exec("vol unmount $row->name");
            sleep(1);
            echo $ssh->exec("vol offline $row->name");
            sleep(1);
            echo $ssh->exec("vol delete $vol_name \n y");
            $loesch = mysqli_query($db, "DELETE FROM volumes WHERE id = '$id'");
            header('Location: splash.html');

?>

Thank's in advance!

Greetings

I see a few possible solutions:

use \n :

$ssh->exec("cd mydir\n./script");

Or create a script with your commands, for example script.sh and save it in UNIX format:

cd mydir
./script

Then exec the script:

$script = file_get_contents("script.sh");
$ssh->exec($script);

Use either a ; or a && to separate the commands.

ssh2_exec($connection, 'command1 ; command2');   //run both uncondtionally)
ssh2_exec($connection, 'command1 && command2');  //run command2 only if command1 succeeds

Use stream_set_blocking() like this:

$cmds = [ 'ls', 'ps ux' ];
$connection = ssh2_connect( '127.0.0.1', 22 );
ssh2_auth_password( $connection, 'username', 'password' );
$output = [];
foreach ($cmds as $cmd) {
    $stream = ssh2_exec( $connection, $cmd );
    stream_set_blocking( $stream, true );
    $stream_out = ssh2_fetch_stream( $stream, SSH2_STREAM_STDIO );
    $output[] = stream_get_contents($stream_out);
}

You will find all the output in the array $output.
