If the error still says "Class 'COM' not found", it is likely that the problem is not related specifically to the EasyDAClient component. It is the 'COM' class, that is a wrapper for COM objects, which is not found - not the EasyDAClient.

You therefore need to resolve this with your PHP installation. We are not PHP experts here, and I am afraid we cannot help further at this point.

If you remove (or comment out) the second statement, i.e. the whole assignment from the ReadItemValue method call, does it still show the same error?

I am trying to determine whether the problem is in the EasyDAClient client instantiation (the first statement), or the OPC read (the second statement).
