hi @Majkl578 , while it is true a web server is not absolutely needed, note that most PHP users configure IIS / Apache.

[Majkl578]

Or FPM + nginx.
But that doesn't make it a prerequisite for installing this extension. There is barely any relation between web server SAPI and using mssql extension, also you don't need a webserver configured to run PHP to use it. Right now this feels like a forced IIS advertisement.

[yitam]

You're right @Majkl578 . We will start updating our readme and/or other online docs for the upcoming preview, and we will consider your suggestion.

[Majkl578]

Thanks. 👍
