Are there any potential security risks associated with retrieving system information using PHP?

Retrieving system information using PHP can pose security risks if the information being accessed is sensitive or if the server is not properly secured. To mitigate these risks, ensure that only necessary system information is being retrieved and that proper access controls are in place to limit who can access the information. 

<?php
// Ensure that only necessary system information is being retrieved
$systemInfo = array(
    'php_version' => phpversion(),
    'server_software' => $_SERVER['SERVER_SOFTWARE'],
    // Add more necessary system information here
);

// Implement proper access controls to limit who can access the information
if (/* Add access control logic here */) {
    // Retrieve and display system information
    foreach ($systemInfo as $key => $value) {
        echo $key . ': ' . $value . '<br>';
    }
}
?>
