Array Search Problem

Hi, 

  I have the code as shown in the following that I am trying to create the image of based on the file loaded into the file and additional edits. 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. 

  I figured that I may have problems with 

    $key= array_search($location2,$from); //Find out the position of the index in the array

    $colors_style = ";fill:" . $state_colors[$key];  //Use the index from array_search to apply to the color index

Obviously, it is not applying the colors to the states that I would like other than doing it one by one as the order of what is in the $from variable. 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?

<?php

header("Content-type: image/svg+xml"); //Outputting an SVG

$from = $_GET['from'];
$state_colors= $_GET['state_colors'];
$distance_to_destination= $_GET['distance_to_destination'];

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

#Load the Map
$ourFileName= "USA_Counties_with_FIPS_and_names.svg";
$fh = fopen($ourFileName, "r") or die("Can't open file");
$contents = fread($fh,filesize($ourFileName));
$lines2= file($ourFileName);

foreach ($lines2 as $line_num => $line2) {

$style_line_num = $line_num+3;
$line2 = trim($line2);

      if(preg_match("/^style/",$line2)) {

       $rest = substr($line2,0,-1);         

       for ($j=$line_num;$j<=$style_line_num;$j++){
         if(preg_match("/inkscape:label/",$lines2[$j])) { 
            $location = explode("=",$lines2[$j]);
            $location2 = substr($location[1],1,-6); 
          
            if(in_array($location2, $from)) {
          
             $key= array_search($location2,$from); //Find out the position of the index in the array
             $colors_style = ";fill:" . $state_colors[$key];  //Use the index from array_search to apply to the color index
             $rest2 = substr($line2,0,-1). $colors_style . "\"";           
             echo $rest2 . "\n";
            }
            else echo $line2 . "\n";            

         } //end preg_match inkscape       
     } //end for loop
   }  //If preg_match style

     else echo $line2 . "\n"; //else if preg_match style    
 } //end for each   

fclose($fh);
?>

Thanks for your help.
