PHP showing the name of the current file

Sometimes there is a need to show the name of the current file.
Using $_SERVER[‘PHP_SELF’] will only show the file that is executed (not the a included file)
Using __FILE__ gives the current file (with a full path)

For this example running.php is accessed in the browser/cli.

echo $_SERVER['PHP_SELF']; //will show running.php
echo __FILE__; //will show included.php
