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 p=
roblem here appears to be that no matter what value I have in the $distance=
_to_destination variable=2C 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=2C but I have to match up =
the colors based on the values of the correct states.=20
I figured that I may have problems with=20
$key=3D array_search($location2=2C$from)=3B //Find out the position of =
the index in the array
$colors_style =3D "=3Bfill:" . $state_colors[$key]=3B //Use the index =
from array_search to apply to the color index
Obviously=2C 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 variabl=
e. Could someone please give me some hints on how I could do the array_sear=
ch here based on the "value" of the values in the $distance_to_distance and=
apply the color to the states?
header("Content-type: image/svg+xml")=3B //Outputting an SVG
$from =3D $_GET['from']=3B
$state_colors=3D $_GET['state_colors']=3B
$distance_to_destination=3D $_GET['distance_to_destination']=3B
$from =3D explode("-"=2C $from)=3B
$state_colors=3D explode("-"=2C $state_colors)=3B
$change =3D explode("-"=2C$change)=3B
#Load the Map
$ourFileName=3D "USA_Counties_with_FIPS_and_names.svg"=3B
$fh =3D fopen($ourFileName=2C "r") or die("Can't open file")=3B
$contents =3D fread($fh=2Cfilesize($ourFileName))=3B
$lines2=3D file($ourFileName)=3B
foreach ($lines2 as $line_num =3D> $line2) {
$style_line_num =3D $line_num+3=3B
$line2 =3D trim($line2)=3B
if(preg_match("/^style/"=2C$line2)) {
$rest =3D substr($line2=2C0=2C-1)=3B =20
for ($j=3D$line_num=3B$j<=3D$style_line_num=3B$j++){
if(preg_match("/inkscape:label/"=2C$lines2[$j])) {=20
$location =3D explode("=3D"=2C$lines2[$j])=3B
$location2 =3D substr($location[1]=2C1=2C-6);

if(in_array($location2=2C $from)) {
=20
$key=3D array_search($location2=2C$from)=3B //Find out the pos=
ition of the index in the array
$colors_style =3D "=3Bfill:" . $state_colors[$key]=3B //Use t=
he index from array_search to apply to the color index

echo $rest2 . "\n"=3B

(almost) all the tricks are in the comments of the help page for a
function, on php.net
but all functions accept only a given (and usually documented) set of
parameter(type)s, so you'll probably have to prepare the var, or even
call the function in a loop, outputting to yet another descriptively
named array that'll be used as "wanted list" later in the code.

Hi,
At the time when I am writing this=2C looks like I already got the functi=
ons I needed. It turned out that I had to use some array_combine=2C sorting=
the items by keys instead of values as well as using array_keys to get the=
values I needed.=20
Thanks for pointing me towards the right direction.=20
