Support PHP (Laravel+Symphony) among our SDKs

The SDK should implement the following:

• a way to H.recordException following the otel exception reporting spec.
• a way to instrument php/laravel logging libraries. if the php/laravel sdk supports logs natively, it would be great to route them to as LogRecords on v1/logs, but if not, fine to support them as trace events.

as part of the exception implementation, if laravel libraries follow a common format for tracing HTTP request handlers, it would be great to wrap those as native otel traces.

We should build the SDK based on the opentelemetry sdk. There is a guide for php laravel specifically, so we should follow best practices here in terms of collecting the available data.

Requirements:

• a init method that sets up the PHP instrumentation to collect console logs automatically.
• a recordException method that allows capturing errors manually (see java sdk as an example).
• Laravel instrumentation that will hook into the framework to collect errors / logs automatically, without the need for a user to manually report errors.

Some getting started pointers on our docs! Please let us know if you have feedback, I'm happy to add to them.
