Echo last value in loop?

[Anon]

How can I get this loop to echo only the last $counter value?

for($counter=0; $counter<$length; $counter++)
    	{
    	echo "$counter";
    	}

}

Think about that one again.

for($counter=$length+1; $counter>$length; $counter--)
{
echo "$counter";
}
}

Think harder. (Hint: you've just created a loop that is guaranteed to execute exactly once.)

I suspect that the original question was simplified beyond the point of necessity. :-)
