What are the security implications of using Telnet for communication, and what alternative methods can be considered in PHP development?

Using Telnet for communication in PHP development poses security risks as it transmits data in plain text, making it susceptible to interception and unauthorized access. To address this issue, developers should consider using more secure alternatives such as SSH or HTTPS for encrypted communication. 

// Example of using SSH2 extension in PHP for secure communication
$connection = ssh2_connect('example.com', 22);
ssh2_auth_password($connection, 'username', 'password');

// Example of using cURL in PHP for secure HTTPS communication
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://example.com/api');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
