Why am I getting two different values for the environment variable PHPRC?
I've installed PHP 7.2.12 using the latest version of XAMPP.
I ran the code phpinfo(); and saw the output in the browser window.
In the output, under the heading Apache Environment I saw an environment variable named PHPRC which has a value xamppphp
Then I created a file named demo.php and wrote below code in it and run the same code file and see the output in my web browser.
<?php
var_dump($_ENV['PHPRC']);
?>
I saw the below output in my browser window :
Notice: Undefined index: PHPRC in C:xampphtdocsdemo.php on line 2
NULL
Why so?
Why am I getting different and unexpected output when I tried to see the value of the environment variable PHPRC using superglobal array $_ENV['PHPRC']?

As the header "Apache Environment" tells you, this is set by the web server, not the OS, so won't be available within $_ENV. Instead try using the apache_getenv() function.
echo apache_getenv("PHPRC");
