In what ways can PHP developers optimize their code for handling SSH connections and executing commands to retrieve specific information, like WLAN status?

To optimize PHP code for handling SSH connections and executing commands to retrieve specific information like WLAN status, developers can use libraries like phpseclib to securely interact with SSH servers. By properly managing SSH connections and executing commands efficiently, developers can retrieve the required information without causing performance bottlenecks or security vulnerabilities. 

<?php
require('Net/SSH2.php');

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

$command = 'iwconfig';
$output = $ssh->exec($command);

echo $output;
?>
