Check if a file was included or loaded

Question

Is there any elegant way to check if a file was included by using include/include_once/require/require_once or if the pag

Answer 1

It's sooo simple.. I have made something like this:

//code for file.php
if (!isset($file_included)){
   echo "It was loaded!";
} else {
  echo "It was included!";
}

//code for loader.php
//proves that atleast loader.php has loaded,
//not the file we targeted first..
$file_included = true;
include("../file.php");

And that's it.. as simple as in python.
