Are there best practices for handling session management in PHP scripts that interact with services via SSH2?

When interacting with services via SSH2 in PHP scripts, it is important to properly handle session management to ensure secure and efficient communication. One best practice is to establish a persistent SSH2 connection and reuse it for multiple commands, rather than creating a new connection for each command. This can help reduce overhead and improve performance. 

// Establish SSH2 connection
$connection = ssh2_connect('example.com', 22);
ssh2_auth_password($connection, 'username', 'password');

// Execute multiple commands using the same connection
$stream = ssh2_exec($connection, 'command1');
stream_set_blocking($stream, true);
$output1 = stream_get_contents($stream);

$stream = ssh2_exec($connection, 'command2');
stream_set_blocking($stream, true);
$output2 = stream_get_contents($stream);

// Close the SSH2 connection when done
ssh2_disconnect($connection);
