[mapserver-users] FastCGI & PHP MapScript Problem

[Keith Moss]

Just replying to my own post with the solution/workaround we found.
 
loadParams() looks for the query string in the CGI enviroment variables and parses them to fill the OWSRequest object. Now, for whatever reason our FastCGI setup didn't have the expected parameters and this was causing the process to die as explained in http://mapserver.org/ogc/mapscript.html#use-in-non-cgi-environments-mod-php-etc.
 
So we are now just parsing the query string and manually filling the Request object.

Subject: [mapserver-users] FastCGI & PHP MapScript Problem


Hi all,
 
I've run into a problem with running PHP MapScript and FastCGI on a development server I've been setting up. It's a Windows Server 2003 box with IIS6 and I've installed MapServer 5.4 and PHP 5.2.9. I obtained the necessary dlls for PHP MapScript from the MS4W MapServer 5.4.0rc2 release. The FastCGI install is version 1.0 from iis.net.
 
I tested the basic install before adding FastCGI and everything worked properly in my test file (a GetCapabilities request on a simple one image mapfile). I couldn't find any IIS-specific install instructions for FastCGI so I attempted to adapt the instructions given here for Apache: http://www.maptools.org/ms4w/index.phtml?page=README_INSTALL.html#f-fastcgi
 
Running the GetCapabilities request again throws me the following 500 error:
 

FastCGI Error

The FastCGI Handler was unable to process the request.

Error Details:

*	The FastCGI process exited unexpectedly 
*	Error Number: -2147467259 (0x80004005). 
*	Error Description: Unspecified error 


HTTP Error 500 - Server Error.
Internet Information Services (IIS)


 

I've reduced the problem to a simple test case that creates a request object and initialises it.

<?php
$request = ms_newowsrequestobj();
$request->loadparams();
?>

The loadparams() call is the source of the problem but I've been completely unable to find a solution.

So far this is the only piece of code I can find that will cause the error. All other normal PHP operations and MapScript code that I've tried work without issue

This one has me quite stumped, any help would be much appreciated.

cheers
