PHP agent for auto-instrumentation

Hello, I have php application. I want to get tracing on it, without manually writing code to start all traces, add spans and others of this fashion. For backend I want to use grafana tempo (hosted on grafana cloud). Unfortunately I'm unable to find any agent which will do auto instrumentation for me, which is not commercial(Datadog agent claims that it can do auto instrumentation). Anybody have experience with tracing php apps? If so what are you using and does it support auto instrumentation https://mobdro.bio/ .
