Answer 1

you want the constant:

__FUNCTION__

Answer 2

You can use the magic constants __METHOD__ or __FUNCTION__ depending on if it's a method or a function... =)

Answer 3

what i know

you can get all of the function you create

$arr = get_defined_functions();

will print [user] => Array ( [0] => functionname )

Answer 4

If you are using PHP5 you can try this:

function a()
{
  $trace = debug_backtrace();
  echo "Function name is " . $trace[0]["function"];
}
