# OpenTelemetry Extension

### 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:

```text

B3Propagator::getB3SingleHeaderInstance()

```

For B3 multi header:

```text

B3Propagator::getB3MultiHeaderInstance()

```

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

header.
