mapscript map loading error

Hi!

Here's the answer to your questions:

> - is your tmp-dir writeable for the webserver?

Yes it is. I've tested my mapserver installation successfully using
CGI forms (the itasca samples, in particular) instead of PHP
/mapscript. These CGI webpages performs well and writes their images
in a temp folder I made (/usr/local/apache2/htdocs/tmp/).

The output in the browser (as well as the source code) is simply these text:

"php_mapscript.so loaded. /usr/local/apache2/htdocs/recipe1/hello.map"

Which are text echoed from the php code (see my php code below) from
line 3 and 5. There are no lines for the image at all. Actually, I
added these text to locate where the problem is in my php code.
Otherwise, the output in the browser would be a blank page.

Maricris
