Here is what I wanted to do:

$from = "Adair, OK-Alfalfa, OK-Atoka, OK-Beaver, OK-Beckham, OK-Blaine, OK-Bryan, OK-Caddo, OK-Canadian, OK-Carter, OK-Cherokee, OK-Choctaw, OK-Cimarron, OK-Cleveland, OK-Coal, OK-Comanche, OK-Cotton, OK-Craig, OK-Creek, OK-Custer, OK-Delaware, OK-Dewey, OK-Ellis, OK-Garfield, OK-Garvin, OK-Grady, OK-Grant, OK-Greer, OK-Harmon, OK-Harper, OK-Haskell, OK-Hughes, OK-Jackson, OK-Jefferson, OK-Johnston, OK-Kay, OK-Kingfisher, OK-Kiowa, OK-Latimer, OK-Le Flore, OK-Lincoln, OK-Logan, OK-Love, OK-Major, OK-Marshall, OK-Mayes, OK-McClain, OK-McCurtain, OK-McIntosh, OK-Murray, OK-Muskogee, OK-Noble, OK-Nowata, OK-Okfuskee, OK-Oklahoma, OK-Okmulgee, OK-Osage, OK-Ottawa, OK-Pawnee, OK-Payne, OK-Pittsburg, OK-Pontotoc, OK-Pottawatomie, OK-Pushmataha, OK-Roger Mills, OK-Rogers, OK-Seminole, OK-Sequoyah, OK-Stephens, OK-Texas, OK-Tillman, OK-Tulsa, OK-Wagoner, OK-Washington, OK-Washita, OK-Woods, OK-Woodward, OK
";
$state_colors= "#FFFFCC-#FFFFCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FFCCCC-#FF9999-#FF9999-#FF9999-#FF9999-#FF9999-#FF9999-#FF9999-#FF9999-#FF9999-#FF9999-#FF9999-#FF9999-#FF9999-#FF9999-#FF9999-#FF9999-#FF9999-#FF9999-#FF9999-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF-#0DCCFF";
$change= "207-158-189-220-134-74.9-174-75.1-38-125-173-215-390-39-141-92.1-121-175-80.1-95.4-191-124-169-101-77-52-117-155-188-176-169-114-158-122-141-107-43-122-181-223-53.7-41.5-131-112-144-147-48-249-141-101-155-81.4-158-92.3-16.3-105-153-186-108-69.2-146-103-53.4-225-140-136-80.4-179-93.3-277-136-110-136-143-103-183-141";;

$from = explode("-", $from);
$state_colors= explode("-", $state_colors);
$change = explode("-",$change);

$new_array = array_combine($from,$change);
print_r($new_array);

Although array_combine does put the two arrays together, I cannot really "sort" with the array, because there is text and numeric in there. Plus, array_search seems to be only able to search through one dimension. I would really like to know how I can first sort through the $new_array according to the "numeric" and NOT the "text". 

I then would like to use the "index" after the sort to use as the "key" to find out what "color" I am supposed to use according to the position. 

Is this possible? And, are there some directions on where I can start this?

Thanks for your help.

Alice
