IP addresses are unique identifiers assigned to devices connected to a network. In the context of web development, it is essential to know the IP address of a client’s device for tracking activity and security reasons. In PHP, there are several ways to get the IP address of a client’s device, whether it is a local or remote IP. In this article, we will explore the best practices and methods to get the IP address of a PC in PHP.
Using $_SERVER variables
One of the most common ways to get the IP address of a client’s device in PHP is by using the $_SERVER array. The $_SERVER array is a superglobal variable that provides information about the server and the client’s environment. The $_SERVER[‘REMOTE_ADDR’] variable returns the IP address of the client’s device.
However, it is essential to note that $_SERVER[‘REMOTE_ADDR’] may not always return the accurate IP address, especially if the user is behind a proxy. In such cases, the $_SERVER[‘REMOTE_HOST’] variable can be used to get the hostname of the client’s device.
Here’s an example code snippet to get the IP address of the client’s device using $_SERVER variables:
Using getHostByName() function
The getHostByName() function can be used to get the IPv4 address corresponding to a given internet host name. It takes a hostname as an argument and returns the corresponding IP address.
Additionally, the gethostbyaddr() function can be used to convert an IP address to a hostname.
Here’s an example code snippet to get the IP address of the client’s device using getHostByName() function:

Using getenv() command
The getenv() function is used for the retrieval of values of an environment variable in PHP. The getenv(«REMOTE_ADDR») command can be used to get the IP address of the client’s device.
Here’s an example code snippet to get the IP address of the client’s device using getenv() command:
Using exec() function
The exec() function is used to run an external program in php and fetch the MAC address of the connected client. However, this method is not recommended for security reasons and may not work on all servers.
Here’s an example code snippet to get the MAC address of the connected client using exec() function:
Getting IP address in Laravel
Laravel is a popular PHP framework for web development. To get the client’s IP address in Laravel, we can use $_SERVER[«REMOTE_ADDR»] to retrieve the IP address.
Here’s an example code snippet to get the IP address of the client’s device in Laravel:
$client_ip = $_SERVER["REMOTE_ADDR"]; echo "Client's IP Address: " . $client_ip;

Regarding Linux vs. macOS, that is not a difference in OS or PHP. macOS sets the hostname to .local. Open a terminal window and run `hostname` to check. The local hostname can be set on macOS under the Sharing Preferences (or Settings if Ventura 13 or newer).
Since I built a PHP app that runs on Linux Windows and MacOS I just discovered that using gethostname() behaves differently on different OSes. Linux will return «hostname» while MacOS 10.15 will return «hostname.local» . Have yet to determine how Windows behaves but the difference is worth noting. Only a few days ago I was wanting to get the LAN extension in Linux and was never able to. I was oly hable to get «hostname». In MacOS it is just there. with «hostname.local»
As your program grows, you will probably want to put your function definitions into a file and reuse them in multiple pages, and even group them into categories, and so on.

Why you just don´t copy your get_domain() function into the other file, just after the connect function ? That should work!
A function you have written can be used anywhere within the same file it is declared, it doesn’t have to be immediately afterwards — indeed that’s part of the point of it being a function in the first place! So add your function definition to the top of the file next to the definition of function connect( . ) , and then in your HTML, you can just use it:
(Note that I’ve used echo rather than print — they do the same thing, but echo is the more commonly used name in PHP.)
As your program grows, you will probably want to put your function definitions into a file and reuse them in multiple pages, and even group them into categories, and so on. This is what include and require (and their variants include_once and require_once ) are for.
Even if you do have a page like that on your site, you probably want to make the URL relative to the root of your domain, not in the current directory, in which case you would need a leading ‘/’ :

Firstly the condition if IP from share internet.
if (!empty($_SERVER["HTTP_CLIENT_IP"]))
The second conditon is to check the ip when the client use the proxy. $_SERVER[«HTTP_X_FORWARDED_FOR»] can check the real IP from client although access from a proxy.
elseif (!empty($_SERVER["HTTP_X_FORWARDED_FOR"]))
Print the IP Addres in HTML element. This will print user’s real IP Address does’t matter if user using proxy or not.
