What are common pitfalls when using SSH2 in PHP for file access?

One common pitfall when using SSH2 in PHP for file access is not properly handling errors or exceptions. It is important to check for errors after each SSH2 function call and handle them appropriately to prevent unexpected behavior in your application. Additionally, make sure to close the SSH connection properly after you are done using it to avoid resource leaks. 

$connection = ssh2_connect('example.com', 22);
if (!$connection) {
    die('Unable to establish SSH connection');
}

if (!ssh2_auth_password($connection, 'username', 'password')) {
    die('Unable to authenticate');
}

$sftp = ssh2_sftp($connection);
if (!$sftp) {
    die('Unable to create SFTP session');
}

// Perform file operations here

ssh2_disconnect($connection);
