#33086 [Opn->Fbk]: Weird COM behavior differences in CGI and CLI

ID: 33086 Updated by: wez@php.net Reported By: hmp96 at yahoo dot co dot uk -Status: Open +Status: Feedback Bug Type: COM related Operating System: Windows XP SP2 PHP Version: 5.0.4 New Comment: I can assure you that PHP does absolutely nothing differently in the COM extension, regardless of which SAPI is in use. I suspect that this is somehow related to the CGI running with a more restricted token than CLI, and this is not something that PHP can fix. Please provide use variant_get_type() on the vendor fields to see if there is any difference in the types coming back from there. If you run the CGI from a dos box (eg: just like the CLI), are there any differences?

Basically, I am querying the "WinMgmts:" using COM and the WMI's WQL query I provide is "Select * From Win32_Product". All fields are retrieved fine, except for the Vendor field which is sometimes lacking information; this only happens when the script is running in a CGI environment, but the values are retrieved fine in a CLI environment, i.e. script run from the command line. The script in the "Reproduce Code" section will suffice when testing in CGI and a CLI environment. Note, if you are having problem running a WMI related script on IIS, thats probably because the security needs to be tweaked using WMI Control snap-in from MMC. Reproduce code: --------------- <pre> <?php $wmi = new COM("WinMgmts:root/cimv2"); $colProducts = $wmi->ExecQuery("Select * From Win32_Product"); echo "Applications Installed on Local Machine\r\n"; try { foreach($colProducts as $objProduct) { printf("Name: %s, Version: %s, Vendor: %s\r\n", $objProduct->Name, $objProduct->Version, $objProduct->Vendor); } } catch (Exception $e) { echo $e->GetMessage(); } ?> </pre> Expected result: ---------------- When run, it should fill the 'Vendor' field of the Win32_Product class in a CGI/ISAPI environment. Basically it should be same as the CLI environment's output. Even some of the applications are missing when run in a CGI environment.
