Documentation ------------- [](#documentation) Getting started --------------- [](#getting-started) ### Manual setup [](#manual-setup) See ### SDK Builder [](#sdk-builder) See [https://github.com/open-telemetry/opentelemetry-php/blob/main/examples/sdk\_builder.php](https://github.com/open-telemetry/opentelemetry-php/blob/main/examples/sdk_builder.php) ### Autoloading [](#autoloading) SDK autoloading works with configuration values provided via the environment (or php.ini). The SDK can be automatically created and registered, if the following conditions are met: - `OTEL_PHP_AUTOLOAD_ENABLED=true` - all required [SDK configuration](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/sdk-environment-variables.md#general-sdk-configuration) is provided SDK autoloading will be attempted as part of composer's autoloader: ``` require 'vendor/autoload.php'; $tracer = \OpenTelemetry\API\Globals::tracerProvider()->getTracer('example'); $meter = \OpenTelemetry\API\Globals::meterProvider()->getMeter('example'); ``` If autoloading was not successful (or partially successful), no-op implementations of the above may be returned. See [https://github.com/open-telemetry/opentelemetry-php/blob/main/examples/autoload\_sdk.php](https://github.com/open-telemetry/opentelemetry-php/blob/main/examples/autoload_sdk.php) for a more detailed example.
