Error:

Fatal error:uncaught exception ' com_exception ' with message ' Failed to create COM object ' internetexplorer.application ': Access Denied
Calling IE in PHP uses the following code:

Browser = new COM ("Internetexplorer.application");

No normal call, direct error:

Fatal error:uncaught exception ' com_exception ' with message ' Failed to create COM object ' internetexplorer.application ': Access denied.

The reason is that the COM component of IE prohibits normal account access by default, and the workaround is as follows:
1. Open Control Panel-Administrative Tools-Component Services
2. Open the console root in the Component Services panel-Component Services-computers-My Computer-DCOM config (e.g.)

3. Locate Internet Explorer (Ver 1.0) in the right window to open the Properties window and switch to the Security tab

4. In the Security tab, "Launch and Activation Permissions" Select Custom, edit, add the IIS account used by the website or add the Guests group OK (for example).

5, restart IIS, should now be able to invoke the normal ie.
