Yes, I found a "recursive" way to find out the "index" like I wanted, by doing something like
$from = explode("-", $from);
$state_colors= explode("-", $state_colors);
$change = explode("-",$change);
$count = count($new_array);
$i=0;
foreach ($new_array as $key => $value){
echo $i . " " . $key . " is " . $value . " miles away<br />";
$i++;
}
You can see it is not very elegant, and plus, I created the $new_array so I could do the ordering according to the values of the change array. I can tell that since this is not a single array, which is probably why array_search does not work.
Since I don't need the "value" of my "new_array" here, I am still finding out how to "strip off" the values here without having to flatten my array. Is what I am trying to do here possible? Or, is there a trick in array_search that I could use to find the index without having to strip off anything?
Thanks for your help.

The problem here appears to be that no matter what value I have in the $distance_to_destination variable, it does not affect any changes on the map. What I am trying to do here is to create a map based on the pre-passed through colors of individual states from another program, but I have to match up the colors based on the values of the correct states.

Could someone please give me some hints on how I could do the array_search here based on the "value" of the values in the $distance_to_distance and apply the color to the states?
