1. I created a DLL to calculate something. Is there any way to run this DLL in PHP?
You cannot operate a simple DLL in PHP. If the DLL contains a COM server and implements the IDispatch interface, you can operate it.
2. What does 'unsupported variant type: xxxx (0 xxxxx) 'mean?
There are many VARIANT types and their collections. the vast majority have been supported, but a few do not. arrays are not fully supported. Only one-dimensional arrays are supported. if you still find unsupported data types: Send a bug report (if no report is available) and provide as much information as possible.
3. Is it possible to operate on visual objects in PHP?
It is usually possible. however, PHP is mostly used to run scripts on web server devices, and visualization objects never appear on the server desktop. if you use PHP as an application script such as a PHP-GTK, there is no limit to operating visualization objects through COM.
4. Can I store COM objects in the session?
No. COM instances are considered resources. Therefore, they can only work in a single script program.
5. How can I capture COM errors?
Currently, there are no other tools to track COM errors. Apart from PHP (@, track_errors,...), we are considering a method to implement it.
6. Can I generate DLL files in PHP, just as I did in Perl?
No. Unfortunately, there is no such PHP tool.
7. What does 'unable to obtain IDispatch interface for CLSID {xxxxxxxx-xxxx-xxxxxxxxxxxx} 'mean?
