通过composer安装

编辑composer.json文件

{
  "minimum-stability": "dev",
  "require":           {
    "jukylin/jaeger-php" : "^2.0",
    "opentracing/opentracing":"1.0.0-beta5"
  }
}

执行composer update

$config = Config::getInstance();
$tracer = $config->initTracer('example', '0.0.0.0:6831');

$config->gen128bit();

$spanContext = $tracer->extract(Formats\TEXT_MAP, $_SERVER);

$serverSpan = $tracer->startSpan('example HTTP', ['child_of' => $spanContext]);

$serverSpan->addBaggageItem("version", "2.0.0");

$clientTrace->inject($clientSapn1->spanContext, Formats\TEXT_MAP, $_SERVER);

//can search in Jaeger UI
$span->setTag('http.status', "200");

//log record
$span->log(['error' => "HTTP request timeout"]);

$config->setDisabled(true);

不支持分布式上下文传递

$config::$propagator = \Jaeger\Constants\PROPAGATOR_ZIPKIN;

$span->finish();
$config->flush();
