Biggest Value

I've got 4 variables - they all equal different numeric values.

$Group1 = 44
$group2 = 14
$group3 = 77
$group4 = 64

I want to draw a line between 3 - 4 - 1 - 2 using GD so I need to order them.

How can I work out the order? maybe even starting with $Group1 and working our who has the next highest number?

I suggest using an array, then sort the array.

ant array would sort them

$group3
$group4
$group1
$group2

but then i don't know who $group1 is. For example how would the line go from $group1 to $group2

I think i need to if statemetn which will work out who follows $group1 and draw a line to the winner - how would like look though?

I'm thinking of something like this:

$groups = array('1' => 44, '2' => 14, '3' => 77, '4' => 64);
asort($groups);
print_r($groups);
