如何用PHP调用自己编写的COM组件?

Option Explicit
Private MyScriptingContext As ScriptingContext
Private MyApplication As Application
Private MyRequest As Request Private MyResponse As Response
Private MyServer As Server
Private MySession As Session Public

Sub OnStartPage(PassedScriptingContext As ScriptingContext)
Set MyScriptingContext = PassedScriptingContext
Set MyApplication = MyScriptingContext.Application
Set MyRequest = MyScriptingContext.Request
Set MyResponse = MyScriptingContext.Response
Set MyServer = MyScriptingContext.Server
Set MySession = MyScriptingContext.Session
End Sub

Public Sub OnEndPage()
Set MyScriptingContext = Nothing
Set MyApplication = Nothing
Set MyRequest = Nothing
Set MyResponse = Nothing
Set MyServer = Nothing
Set MySession = Nothing
End Sub

Public Function Test_Number(num) As Variant
If num < 0 Then Get_Number_Attrib = -1
If num > 0 Then Get_Number_Attrib = 1
If num = 0 Then Get_Number_Attrib = 0
End Function
