B3 Propagator

B3 is a propagator that supports the specification for the header "b3" used for trace context propagation across service boundaries.(https://github.com/openzipkin/b3-propagation). OpenTelemetry PHP B3 Propagator Extension provides option to use B3 single header(https://github.com/openzipkin/b3-propagation#single-header) as well as B3 multi header (https://github.com/openzipkin/b3-propagation#multiple-headers) propagators.

Usage

For B3 single header:

B3Propagator::getB3SingleHeaderInstance()

For B3 multi header:

B3Propagator::getB3MultiHeaderInstance()

Both of the above have extract and inject methods available to extract and inject respectively into the header.
