[SOLVED] PHP - How to determine the file is in public_html folder?

Issue

I am using the following $_SERVER variables in my include file.

$page_url = "https://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$ip_address = $_SERVER['REMOTE_ADDR'];

When I include this file to my PHP script located in the home directory for my Cron jobs, it's throwing errors Undefined array key "HTTP_HOST", Undefined array key "REQUEST_URI", Undefined array key "REMOTE_ADDR" to the error_log file.

To avoid this, I want to make this code to show only if the file is in the public_html directories. How do I say it with PHP if statement?

Thanks!

Solution

Based on iazaran's response, this code is working for me!

if (strpos(getcwd(), 'public_html') !== false) {
  $page_url = "https://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
  $ip_address = $_SERVER['REMOTE_ADDR'];
}

I thought it could be useful for someone like me.
