I'm sorting the key. It doesn't work. ksort is the only choice I have, 
right?

Ok, let's approach this question differently.
Right now the frequency of each word is in value.
How do I put the frequency of each word in the key?

I'm fuzzy when it comes to arrays. I can do this is MySQL. All I need is 
an id and two varchars and then I know how to sort any way I want. But I 
am processing dynamic text files. MySQL is not an option; data changes 
too much. PHP is faster and more efficient. I'm just no good at arrays.

Here is my code:
---------------snip-------------------
$mynewstring = "http://foo.com/bigtextfile.txt";;

$words = preg_split('/[[:space:]]+/',$mynewstring);

foreach ($words as $word) {
    $freq[$word]++;
}

#natcasesort($freq);
ksort($freq);
