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.
Alice
