I have the following problem with the Adobe SVG viewer:
I try to generate a SVG document using PHP. the following code is working
well under Firefox, as well as IE with ASV:
header("Content-type: image/svg+xml");
$graph_title = 'title';
print('');
$svgwidth=500;
$svgheight=400;
?>
http://www.w3.org/TR/SVG/DTD/svg10.dtd">
xmlns="http://www.w3.org/2000/svg"> This is a php-random rectangle test
srand((double) microtime() * 1000000); //initalizing random generator
for ($i = 0; $i < 20; $i+=1) {
$x = floor(rand(0,$svgwidth-1)); //avoid getting a range 0..0 for rand
function
$y = floor(rand(0,$svgheight-1));
$width = floor(rand(0,$svgwidth-$x)); //avoid getting rect outside of
viewbox
$height = floor(rand(0,$svgheight-$y));
$red = floor(rand(0,255));
$blue = floor(rand(0,255));
$green = floor(rand(0,255));
$color = "rgb(".$red.",".$green.",".$
blue.")";
print "\t
style=\"fill:$color;\"/>\n";
}
?>
text-anchor="middle">The servers Date and Time is:
(strftime("%Y-%m-%d, %H:%M:%S")); ?>
text-anchor="middle">You are running:
text-anchor="middle">
If now I want to include the session_start() at the beginning of the code,
in IE I got a pop-up dialog called "download file"

It sounds like it's the SVG plugin you're using on IE that's badly
misbehaving. That said, I've not seen any plugins that correctly pass
across the full headers that the browser would. I tried using sessions
once to secure media files by checking for a valid login against the
session id, but the plugins requesting the video clips didn't send any
cookie data in the header request. As such, it might be better to not
rely on it in this case.

It appears IE does not support svg yet and you need a plugin for it.
However, you could also design your code differently by using Imagemagick to
convert the svg to png.
If that suits your needs, then use the modified code below:
header("Content-type: image/png");
$graph_title = 'title';
$svgwidth=500;
$svgheight=400;
$svg = '
xmlns="http://www.w3.org/2000/svg"> This is a php-random rectangle test';
$svg .= '
text-anchor="middle">The servers Date and Time is: '.date("Y-m-d,
H:m:s").'
text-anchor="middle">You are running:
text-anchor="middle">'.$HTTP_USER_AGENT.'
';
unfortunately, it does not suite my needs. The image must be clickable. The
application I'm developping reads data from a database and display the
information graphically. The user must be able to click on some elements of
the picture, and I have to store the information the user clicked on
(session vars). I cannot tell the user not to use IE, so I have to find
another solution...

IE doesn't display SVG natively, and the plugins for it are pants.
However, IE does make use of its own propitiatory vector language called
VML, This is how the Cufon font replacer system works.

Aurelie:
The image must be clickable?
I must not be understanding something. Anything can be made
clickable, just put it in an anchor, such as:
The previous post mentioned using ImageMagick to convert the svg to
png -- so write that script and place it in an anchor. I don't see
the problem.

Maybe svgweb (by Google) would allow you to achieve your goals:
