Answer 1

Or you can try this: http://code.eyecatch-up.de/?p=155
Update: Relocated the class to http://code.google.com/p/php-class-keyword-density-check/

domain = 'http://code.eyecatch-up.de';          // Define Domain
print_r ($obj->result()); 
?>

above code returns:

Array
(
    [0] => Array
        (
            [total words] => 231
        )

    [1] => Array
        (
            [keyword] => display
            [count] => 14
            [percent] => 6.06
        )
and so on...

works with local and remote files.
