It may well come with them both but I can attest to the fact that only several versions ago, I was forced to use cgi mode with php4.
That was quite unstable with the isapi option.
Why is this important because, if 4 was FIXED recently, they give no mention of it as suddenly being more stable in the past version or two. So why then do we see nothing written for version 4 or version 5 as regards the stability of the isapi configuration?
It's troubling to me that nothing has been officially mentioned. I would be happy with something that even just stated major improvements were made in the isapi stability with IIS 5. :bemused:
