What are the differences between using telnet and SSH when working with Pear in PHP?

When working with Pear in PHP, it is recommended to use SSH instead of telnet for secure communication. SSH provides encryption and authentication mechanisms, ensuring that data exchanged between the client and server is secure. Telnet, on the other hand, sends data in plain text, making it vulnerable to interception. To use SSH with Pear in PHP, you can utilize the Net_SSH2 package. This package allows you to establish secure connections to remote servers and execute commands securely. By using SSH instead of telnet, you can ensure the confidentiality and integrity of your data. 

require_once 'Net/SSH2.php';

$ssh = new Net_SSH2('example.com');
if (!$ssh->login('username', 'password')) {
    exit('Login Failed');
}

echo $ssh->exec('pear install package_name');
