How can PHP Sandboxing be utilized to enhance security when executing external PHP code on a server?

When executing external PHP code on a server, there is a risk of security vulnerabilities if the code is not properly sandboxed. PHP Sandboxing can be utilized to restrict the execution environment of the external code, preventing it from accessing sensitive server resources or performing malicious actions. 

<?php
// Create a new PHP Sandboxing environment
$sandbox = new Sandbox();

// Define restrictions for the sandbox
$sandbox->disable_functions('exec', 'shell_exec', 'system');
$sandbox->disable_classes('PDO', 'mysqli');

// Execute external PHP code within the sandbox
$result = $sandbox->execute($externalCode);

// Output the result of the execution
echo $result;
?>
