Hello,

I ve got a big problem with php/mapscript.I ve tried a simple "hello world"
example (from Beginning MapServer Open Source GIS Development) and I didn't
get any error message, but the browser couldn't generate the rendered pic. I
don't know what the problem could be, but all codes what I ve made had the
same problem. I attached the bad codes. Thx for ur help and I'm looking
forward to your answer.

*The php/mapscript file:*

<?php
dl('php_mapscript.dll');

$image_name = sprintf("phpms-hello%0.6d",rand(0,999999)).".png";

$map = ms_newMapObj("c:/ms4w/Apache/htdocs/hello_world/hello.map");

$image=$map->draw();

$image->saveImage("c:/ms4w/tmp/ms_tmp/".$image_name);

?>

<html>
<head><title>PHP MapScript Hello World</title></head>
<body>
<form action="hello.php" method="POST">
    <input type="image" name="img"
        src="c:/ms4w/tmp/ms_tmp/<?php echo $image_name; ?>">
</form>
</body>
</html>

*The map file:*

# "Hello World" mapfile

     END
END
END
