Getting the Function name of the Calling Function- How ?

I guess the Subject is a little ambiguos. I want to get the function
name which calls the target function.

Like

function xxx()
{
....
....
yyy(2,3);

}

function zzz()
{
....
yyy(5,6);
.....

}

function yyy($a,$ab)
{
...
...
echo "yyy() has been called by the function - ".$functionname;

}

Now how can I get the name of the function tat calls yyy().

This will be really useful for Error logging purposes.

If you're using this for anything other than debugging or error
logging it suggests a problem with your code.
