Answer 1

you are getting the errors because you need to authenticate to SharePoint. Are you using SharePoint Online or On Premises. I don't think it will be possible for you to use PHP for the solution, unless you can handle with custom code with the URL redirects when you authenticate to O365.

I had a similar requirement, using Excel to upload to SharePoint and I designed VBA code to connect to SharePoint online, it was hard to maintain and it broke. I recommend you to create a .NET app were you pass the information i.e. (document library, source folder, user name, password, sharepoint site url) and that will work.

I have Microsoft.SharePoint,Microsoft.SharePoint.Client, Microsoft.SharePoint.Client.Publishing and Microsoft.SharePoint.Client.Runtime in project references on Visual Studio and it works like charm.
