Using a DLL With PHP for Dummies

When you create your DLL file, you need to use a module definition file. It will contain something similar to this:

;
;contains the list of functions that are being exported from this DLL
;

DESCRIPTION     "Simple COM object"

EXPORTS
                DllGetClassObject       PRIVATE
                DllCanUnloadNow         PRIVATE
                DllRegisterServer       PRIVATE
                DllUnregisterServer     PRIVATE

That definition allows regsvr32 to find the DllRegisterServer entry point.

Another option you can try is to pass the /n flag to regsvr32.

Regsvr32 [/u] [/n] [/i[:cmdline]] dllname

/u - Unregister server

/i - Call DllInstall passing it an optional [cmdline]; when used with /u calls dll uninstall

/n - do not call DllRegisterServer; this option must be used with /i

/s – Silent; display no message boxes (added with Windows XP and Windows Vista)

Ultimately, before you try to make a DLL work with PHP, you need to be sure your DLL works in general.

I had the same problem and i fixed some steps :

1. open the command line in administrator right (windows + r + type 'cmd') write the PATH where you're your dll file:
   C:\Windows\system32\regsvr32 xwizards.dll(it's example)
   a window show up with "DLLRegisterServer success"
   
2. check your phpinfo() if you're com_dotnet extension

3. now write into your PHP code :

       try    {
     $dll = new COM('<theNameOfDllFile>.<NameOfTheClass>'); //without extension '.dll' for theNameOfDllFile
     $dll->Function(); 
     } catch(Exception $e){
       echo 'error: ' . $e->getMessage(), "\n";}
   

   Now if you know how manage the class and the function of you're dll it's going ok,however no error massage should show up on your screen

   
   

If i wasn't clear let me know and i'll do my best the next time :)
