(PHP Extension) Find My External Public IP Address
To find your external public IP address (not your LAN IP address, such as 192.168.1.* or 172.16.16.*, etc), your application would need to send a request to an HTTP server that can report back on the origin IP address. You can easily write a simple script on your own web server to do it, or you can use a service such as ipify.org.
This example shows how to send a request to the ipify.org endpoint to get your public IP address. For more information, see https://www.ipify.org/
<?php
include("chilkat.php");
// Use "chilkat_9_5_0.php" for versions of Chilkat < 10.0.0
$http = new CkHttp();
$my_ip_address = $http->quickGetStr('https://api.ipify.org');
if ($http->get_LastMethodSuccess() == false) {
print $http->lastErrorText() . "\n";
exit;
}
print 'My Public IP Address: ' . $my_ip_address . "\n";
?>
