A confused Network Admin

Christine -

It is actually not very complicated.  You're using trying to start using
a LOT of different technologies all at once.  Most people don't do that,
so that's why relatively few people can be expected to be as frustrated
as you are <g>.

For example, MapScript is a PHP module.  Most users who want to start
using PHP MapScript are PHP users who would like some maps.  If you were
a PHP user and familiar with PHP and modules, most of your recent email
conversations would be straightforward and obvious.  It's perfectly OK
that you are new to all that, but don't blame MapScript.  It's not being
complicated - it's pretty straightforward.  You'd be having the same
problems with ANY external PHP module.

I'll remind you of my first email to you.  MapScript is NOT a "MapServer
module".  There is a large library of mapmaking functionality in the
MapServer suite.  All that code (think of it as a small collection of
related DLLs) has been wrapped into several interfaces.  One of those is
the MapServer CGI program, which allows CGI requests to be made against
the libraries, and one is the PHP MapScript module, which lets PHP
scripts call functions in the libraries.  They are completely
independent of each other - neither one requires the other.  Some users
use both, and your consultant seems to want to do that.  But they are
two separate things.  You do not need to have MapScript installed to use
the MapServer CGI.

You should go back to the error message you reported from your working
PHP script.  As was mentioned, your script cannot load a module from a
file that is evidently there.  That means that (a) the script doesn't
have permission to load that module or (b) that module has dependencies
it cannot find.

The first place I'd look is whether the C:\PHP directory is on the
search path of the user context running in IIS (usually the
IUSR_<machinename> account).  You can probably just add that directory
to the system search path, although you should probably restart IIS
after doing that (or at least unload the site you're testing).

The consultant told me to have both so I don't understand.  MapScript is
a MapServer module, no?

Christine,

you don't (normally) need both MapServer and MapScript ... you would use

one or the other.  And the versions wouldn't have to match (except 
perhaps for dependencies).

MapScript is completely self-contained ...
