PHP output is not displayed in the OUTPUT in VS Code

I am using code runner and PHP extension pack. I have edit my system variables and added PHP as a path (the php folder is inside XAMPP inside my C drive). I had ran the following the code:

<?php
   $variable = "hello world!";
   echo $variable;
?>

Upon execution, I face this message in the output section

[Running] php "c:\Users\spide\Documents\coding\test.php"

[Done] exited with code=0 in 0.242 seconds

As you can see, there is no output as well as no error message visible. I would like to know what I can do to solve this "error."
