How to get clients IP Address in PHP?

To get the client’s IP address in PHP, you can use the $_SERVER['REMOTE_ADDR'] variable. This variable returns the IP address of the client making the request to the server.

Here is an example of how you can get the client’s IP address in PHP:

<?php

$clientIp = $_SERVER['REMOTE_ADDR'];
echo "The client's IP address is: $clientIp";


Note that this method may not always return the correct IP address, especially if the client is behind a proxy server. In such cases, you can use the $_SERVER['HTTP_CLIENT_IP'] or $_SERVER['HTTP_X_FORWARDED_FOR'] variables to try to get the client’s real IP address.

Here is an example of how you can use these variables to get the client’s IP address:

<?php

$clientIp = '';

if (!empty($_SERVER['HTTP_CLIENT_IP'])) {
    $clientIp = $_SERVER['HTTP_CLIENT_IP'];
} elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
    $clientIp = $_SERVER['HTTP_X_FORWARDED_FOR'];
} else {
    $clientIp = $_SERVER['REMOTE_ADDR'];
}

echo "The client's IP address is: $clientIp";
