This is a basic HTML5 page with PHP!

Originally the array looks like this:
Tom: 100
Mike: 95
Jeff: 90
James: 95
William: 100
Bing: 95

After sorting the array by value using arsort(), the array looks like this:
Tom: 100
William: 100
Mike: 95
James: 95
Bing: 95
Jeff: 90

After sorting the array by key using ksort(), the array looks like this:
Bing: 95
James: 95
Jeff: 90
Mike: 95
Tom: 100
William: 100
