How can DNS entries and Hostheader values be adjusted to make a PHP site externally accessible on an ISS server?

To make a PHP site externally accessible on an IIS server, you need to adjust the DNS entries to point to the server's IP address and configure host headers to map the domain to the site. This can be done through the IIS Manager by adding a binding for the domain to the site. Additionally, ensure that the necessary firewall rules are in place to allow external access to the server.

// Example PHP code to adjust DNS entries and host headers on an IIS server
// This code snippet assumes you have access to the IIS Manager

// Add a binding for the domain to the site
// Replace 'example.com' with your domain and 'SiteName' with the name of your site in IIS
// Ensure the site is listening on port 80 or the appropriate port for HTTP traffic
// This can be done through the IIS Manager interface

// Once the binding is added, update the DNS entries to point to the server's IP address
// This can be done through your domain registrar or hosting provider's DNS management interface
// Create an A record pointing to the server's IP address

// Ensure that the necessary firewall rules are in place to allow external access to the server
// Open port 80 (or the appropriate port) on the server's firewall to allow incoming HTTP traffic
