Bob/Alice/Whatever,

You don't do anything with the SVG file except open it and close it. Opening
and closing a door doesn't walk you through the doorway. Maybe you should
echo the contents of said file after sending a Content-Type header through
to the browser?

Aren't you just opening the file? I think that you need to print it in some
way suitable to your application.
Try using fread() or other function to read the contents of the file.



 Thanks in advance.

If you go the fopen route, you need to get the contents of the file and
print them out to the browser, with the correct SVG headers. All you're
doing here creating a read-only resource to the file.

  Well, I tried, and here is the complete code of the portion I just edited:

#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));
echo $contents;
fclose($fh); 
 
Now I get something on the screen, but still no image: image/svg+xml
Um, is there anything particular I need to put in my code? 


Thanks in advance.

View the source of your browser. Is it showing the SVG code? You need to
output the correct mime-type headers for the SVG, as by default, PHP
outputs headers for HTML. Something like this should do the trick:

header(Content-type: image/svg+xml);

This has to occur before any output has already been sent to the
browser, otherwise you'll get a headers already sent error.
