ultimaker3 extended sendgcode

[sxj1121 4]

I tried to send gcode to my 3d printer by PHP and Python. The following code could connect to it, but couldn't execute any command after running that py file. Any help would be appreciated!

<?php
set_include_path('C:/xampp/htdocs/phpseclib1.0.15');
include('Net/SSH2.php');

$ssh = new Net_SSH2('ip');
if (!$ssh->login('root', 'ultimaker')) {
    exit('Login Failed');
}
echo $ssh->exec('python3 /usr/share/griffin/command_util.py && help');

?>

# 
import paramiko
# realize transport
trans = paramiko.Transport(('ip', 22))
# connection
trans.connect(username='root', password='ultimaker')

# Specify the transport of the sshclient object as the above trans
ssh = paramiko.SSHClient()
ssh._transport = trans
# execute command
stdin, stdout, stderr = ssh.exec_command('python3 /usr/share/griffin/command_util.py \n sendgcode G28')
print(stdout.read().decode())

# close connection
trans.close()

Is there any other way to send gcode to the 3d printer?

For sending arbitrary gcode, pronterface is a good choice: https://github.com/kliment/Printrun

I figured out the reason. Just delete "&&" in PHP or delete"\n" and it would work.
