How can one determine the appropriate parameters to send to a server and interpret the response when querying server information in PHP?

When querying server information in PHP, one can determine the appropriate parameters by referring to the server's API documentation or by inspecting the server's response to identify the required parameters. To interpret the response, one can use PHP functions like json_decode() to convert the response into a PHP array or object for easier manipulation. 

// Example code to query server information and interpret the response
$serverUrl = 'https://api.example.com/server-info';
$parameters = [
    'param1' => 'value1',
    'param2' => 'value2'
];

$response = file_get_contents($serverUrl . '?' . http_build_query($parameters));
$data = json_decode($response, true);

if ($data) {
    // Interpret the response data here
    print_r($data);
} else {
    echo 'Error retrieving server information.';
}
