Hi,

Just went online and saw an SVG generated from Python=2C and wanted to do=
the similar thing by loading the SVG into an PHP script. Here is the scrip=
t that I have:=20

=20
#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
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?=20

Thanks in advance.=20

Alice

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.

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.

Hi=2C



Just went online and saw an SVG generated from Python=2C and wanted to do=
the similar thing by loading the SVG into an PHP script. Here is the scrip=
t that I have:






#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

fclose($fh)=3B



?>



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=

=20
Well=2C I tried=2C and here is the complete code of the portion I just ed=
ited:

#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
echo $contents=3B
fclose($fh);
=20
Now I get something on the screen=2C but still no image: image/svg+xml
Um=2C is there anything particular I need to put in my code?=20


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.
