## Protobuf Runtime library
|
|
|
|
OTLP exporting requires a [protobuf runtime library](https://github.com/protocolbuffers/protobuf/tree/main/php).
|
|
|
|
There exist two protobuf runtime libraries that offer the same set of APIs, allowing developers to choose the one that
|
|
best suits their needs.
|
|
|
|
This package requires `google/protobuf`, which is the native implementation. It is easy to install and a good way to get
|
|
started quickly.
|
|
|
|
Alternatively, and the recommended option for production is to install the Protobuf C extension for PHP. The extension
|
|
makes OTLP exporting _significantly_ more performant. The extension can be installed with the following command:
|
|
|
|
```shell
|
|
pecl install protobuf
|
|
```
|
|
|
|
The extension can be installed alongside the native library, and it will be used instead if available.
