[Resolved] [Resolved] Sessions and php versions

paul_mac

I run php V4.3.1 with gd2 enabled on my Win 98 pc at home and the following code works fine:

file a.php

<?php
session_start();
session_register("x");
session_register("y");
$fileName = "image01.png";
?>
<html>
<head></head>
<body>
<?php
echo "<img src='b.php?fileName=$fileName' border='0'>";
?>
</body>
</html>

file b.php

<?php
session_start();
$fileName = $_GET["fileName"];
$fileName = "images/largeimages/".$fileName;
$m = imagecreatefrompng($fileName);
header("Content-type: image/png");
imagepng($m);
imagedestroy($m);
?>

(I've missed out the processing with the $x and $y arrays for simplicity)

when I load it onto my server webspace PHPV4.1.2 gd1.6.2

it doesn't work, the image fails to appear, yet when I run the following file by typing the full URL address in the URL bar of the browser it works ok, the image appears.

<?php
$fileName = "images/largeimages/image01.png";
$m = imagecreatefrompng($fileName);
header("Content-type: image/png");
imagepng($m);
imagedestroy($m);
?>

Am I doing something wrong?

I've also tried $HTTP_GET_VARS without success

Thanks

After much searching the problem appears to be with the way that php 4.1.2 handles session variables when they are arrays. It doesn't appear to pass them across. I found a site that suggests it can be done by declaring a dummy array

$anArray = new Array(value 1.......valuen);
$_SESSION[$aDifferentArray] = $anarray;

or to use serialize to covert the array into a string

but I couldn't get either way to work!

and have have to resort to repeating work server side that was being calculated client side on the x and y array prior to the image php file being called.
