Developer Call the API via PHP is not working: Session Start

[anonymous-matomo-user]

I tried everything possible to make it work for calling the API via php. The request works fine if isend him via html request,but if i change to "build in", what means using the php version of calling the api, I get always the following message.

session has already been started by session.auto-start or session_start()

I tried it with entries in htaccess files, checked the php settings session.autostart und bootstrap.php. Nothing is working.
I use drupal for the integration and calling the api.
Maybe this helps to find the problem
