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.

Subject: [PHP] session variables and SVG documents
Hello,
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:

$svgheight=400;

The servers Date and Time is:

If now I want to include the session_start() at the beginning of the code,

What am I doing wrong ?

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:
xmlns="http://www.w3.org/2000/svg";>
This is a php-random rectangle test';
for ($i = 0; $i < 20; $i++) {
$x = floor(rand(0,$svgwidth-1));
$y = floor(rand(0,$svgheight-1));
$width = floor(rand(0,$svgwidth-$x));
$height = floor(rand(0,$svgheight-$y));
$red = floor(rand(0,255));
$blue = floor(rand(0,255));
$green = floor(rand(0,255));
$color = "rgb(".$red.",".$green.",".$blue.")";
$svg .= "\tstyle=\"fill:$color;\"/>\n";
}
$svg .= 'text-anchor="middle">The servers Date and Time is: '.date("Y-m-d,
H:m:s").'
text-anchor="middle">You are running:
text-anchor="middle">'.$HTTP_USER_AGENT.'
';
file_put_contents('/tmp/image.svg', $svg);
exec("/usr/bin/rsvg /tmp/image.svg /tmp/image.png");
echo file_get_contents('/tmp/image.png');
?>

Re: [PHP] session variables and SVG documents
Hello,
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.
