php code not running

As i continue with my first ubuntu server, following the lamp installation tutorial at i configured everything without much issue until i decided to create a different php script and upload it to the server. the code is supposed to show your ip (here is the script)


function getUserIpAddr(){
        //ip from share internet
        $ip = $_SERVER['HTTP_CLIENT_IP'];
        //ip pass from proxy
        $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
        $ip = $_SERVER['REMOTE_ADDR'];
    return $ip;

echo 'User Real IP - '.getUserIpAddr();


but when i connect to it through a web browser like ‘server ip/file.php’ all i get is the ‘User Real IP’ message without the actual interesting part wich is the ip, does this mean php isnt executing the code or what am i missing here

Hi @21729179,

It’s possible you are missing some PHP packages/extensions. Can you list what PHP extensions you have installed on your server? Additionally, the version is of importance as well. To list the extensions type in

apt list --installed php*
