What steps can be taken to troubleshoot and debug PHP scripts that interact with Telnet connections?

When troubleshooting and debugging PHP scripts that interact with Telnet connections, one important step is to ensure that the Telnet extension is enabled in PHP. Additionally, checking for errors in the Telnet connection setup, such as incorrect host or port information, can help identify issues. Using error handling techniques, such as try-catch blocks, can also assist in pinpointing the source of errors in the script. 

<?php
// Check if Telnet extension is enabled
if (!extension_loaded('telnet')) {
    die('Telnet extension not enabled.');
}

// Set up Telnet connection
$host = 'example.com';
$port = 23;

try {
    $telnet = new Telnet($host, $port);
    // Perform Telnet operations here
} catch (Exception $e) {
    echo 'Error: ' . $e->getMessage();
}
?>
