How important is it to consider security measures when setting up a PHP server for testing?

It is crucial to consider security measures when setting up a PHP server for testing to prevent potential vulnerabilities and unauthorized access to your system. This includes implementing measures such as setting up proper file permissions, using secure coding practices, and configuring firewall rules to restrict access to the server. 

// Example of setting restrictive file permissions
chmod("/path/to/file.php", 0644);
chmod("/path/to/directory", 0755);

// Example of securely handling user input
$user_input = $_POST['input'];
$clean_input = htmlspecialchars($user_input);

// Example of configuring firewall rules
// This can vary depending on the server configuration
// Consult with your server administrator or hosting provider for specific instructions
