I've tried to follow the instructions, with mixed success for the
individual steps, and no luck getting mapscript to load. Please see my
results interspersed with the instructions, below, and anyone with insight
into the problems I'm having please let me know.
Are there tools to help understand better what is/is not working when PHP
tries to load a DLL? There's got to be something more than "it worked" or
"it didn't"...?
Thanks,
Chris

Done - PHP 5.2.3 installed and running under IIS 5.1 (I'm trying this on my
laptop with Windows XP for now) - doc_root is not set.

Tried everything - can't get any actual errors to be logged. Created the
file, set both NTFS and IIS permissions to allow anyone to write to it, set
the error_log to this file in PHP.ini (phpinfo() confirms that it's set),
ran various error-throwing codes but get no entries in the logfile - don't
know if logging is working or not, but I suspect not. Is this critical for
mapscript to work, or just a useful debugging tool?

Done - downloaded and unzipped 2.2.4

Done - created C:\mapserver and put it in the Environment Variables->System
Variables PATH variable - confirmed by seeing it listed in phpinfo()

Done.

Done - but how can one know the version of the php_mapscript.dll - the file
itself has no version info, nor could I find other docs in the ms4w tree
that indicates which version of mascript is being used. I just left it as
php_mapscript.dll for now.

Done. However, I get this warning for MPR.dll - I think from what I read on
the web that I can ignore this warning?
"Warning: At least one module has an unresolved import due to a missing
export function in a delay-load dependent module."

Nope :( phpinfo() doesn't show anything about "mapscript", and the info()
function provided with cartoweb (which just tries to load mapscript and
then calls phpinfo) also gives warning that mapscript is not loaded.
The only 2 things that appeared anomalous when following the instructions
were my inability to get PHP error logging to work and the warning about
MPR.dll in the dependency walker - are either of those likely candidates
for why mapscript isn't loading?
If it does not, I have no idea why, could be a
