1. I put Read & Execute permissions on "cmd.exe" and "cscript.exe".
2. OLAP.VBS
----------------
Dim cat
Set cat = CreateObject("ADOMD.Catalog")
cat.ActiveConnection = "DATA SOURCE=blackbox;UID=sa;Initial
Catalog=FoodMart
2000;Provider=MSOLAP;Encoding=windows-1250;Roles=skrbnik;"
3. COM_VBS.php
-------------------
<?php
$r = system('cscript.exe c:\OLAP.vbs', $a);
echo "Result = " . $a;
?>
4.Result in Browser
---------------------
Result = 1
No idea, does it work or does it not.
There is no difference in result in Browser concerning of changes the
DATA SOURCE parameter in Connection string. Either Local or Remote OLAP
server, the result is the same.
Did I miss something?

PHP doesn't touch the content of your strings (except to convert to
UTF-16); it passes them on to the COM server, and its the COM server
that's reporting an error.
It seems unlikely that PHP is the cause.
Can you try running your .vbs file from the same environment as PHP?
eg: Create a PHP page that calls system("cscript.exe test.vbs") and
then request that PHP page from your browser.
(you will probably need to replace the MsgBox line with Echo)

After some testing and checking securities on both servers I have found
out that ADOMD is not meant to be a DCOM object. Namely, in the
connection string is written all necessary connection information
(server, user, pass, OLAP Cube, etc.). In my case this is stored in
variable »$dsn«.
Therefore, I have tried to connect to ADOMD COM object locally. In my
reproduce code written above I have replaced the following line:
$cat = new COM('ADOMD.Catalog', array(
"Server" => "blackbox",
"Username" => "administrator",
"Password" => "default"));
with line
$cat = new COM('ADOMD.Catalog');
The connection with OLAP is established but the problem comes in the
following line:
$cat->ActiveConnection = $dsn;
Result in Browser:
Connection with OLAP has been established.
Fatal error: Uncaught exception 'com_exception' with message 'Source:
Microsoft® OLE DB Provider for Analysis Services
Description: Property name was not recognized, 'Encoding''
So, communication is OK, only the parameters stored in $dsn are
wrong or they supposed to be wrong. And why this doubt?
I have checked the same syntax also with VisualScript code stored in
VBS file and works fine with all parameters. Here is the testing
example:
Dim cat
Set cat = CreateObject("ADOMD.Catalog")
cat.ActiveConnection = "DATA SOURCE=blackbox;UID=sa;Initial
Catalog=FoodMart
2000;Provider=MSOLAP;Encoding=windows-1250;Roles=skrbnik;"
MsgBox cat.Name
My impression is that ADOMD COM object works fine with windows
technology (VisualBasic, ASP, etc.) but has problem when is called from
PHP.
I still suspect that could be a PHP internal problem when using ADOMD
COM object. What is your opinion? Could you check this PHP and VBS code
by yourself?
Thanks, Marko

You have to configure the permissions on that DCOM server to allow the
web server to access it.
If you do that, you need to consider how it might affect the overall
security of your system (say there was a remote eval() bug in something
else running on your web server).
Since this is a local configuration issue, it's not a bug in PHP, so
I'm marking it as bogus. You need to read up on DCOM security and
configuration to resolve your problem.

Thank you for your quick resonse. In my previous description I forgot
to mention that Excel works also over DCOM already in version 4.3.6.
So...
I have upgraded PHP to ver.:5.0.4 (Mar 31 2005). The previous
observations and problem remains at it was. Here is the actual result:
------------
Fatal error: Uncaught exception 'com_exception' with message 'Failed to
create COM object `ADOMD.Catalog': Access is denied. ' in
c:\Inetpub\wwwroot\aaa1.php:8 Stack trace: #0
c:\Inetpub\wwwroot\aaa1.php(8): com->com('ADOMD.Catalog', Array) #1
{main} thrown in c:\Inetpub\wwwroot\aaa1.php on line 8
-------------
Any idea what could be a problem?
Thanks for the answer.
Marko
