Hi,
Just went online and saw an SVG generated from Python, and wanted to do the similar thing by loading the SVG into an PHP script. Here is the script that I have:
<?php
#Load the Map
$ourFileName= "USA_Counties_with_FIPS_and_names.svg";
$fh = fopen($ourFileName, "r") or die("Can't open file");
fclose($fh);
?>
The problem is that my screen appears as blank even though I could open up USA_Counties_with_FIPS_and_names.svg and see the entire US Map. Does anyone know what I might have done wrong here?
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.
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.
Alice

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.
Thanks, this time it does the trick.
Thanks,
Ash
