**Curlmetry** is a lightweight tracing library for legacy PHP applications (5.6+).
It exports spans to [SigNoz](https://signoz.io/) or [Jaeger](https://www.jaegertracing.io/) via HTTP, and provides a native PSR-18 client using plain `curl`.

No Guzzle. No Symfony. No Composer autoload hell. Just PSR + curl.

---

✨ Features
----------

[](#-features)

- 📦 PSR-18 client (native curl-based)
- 📡 Exports spans to:
    - OTLP (SigNoz via HTTP JSON)
    - Jaeger (via `/api/traces`)
- 🔧 Span / Tracer / Scope system (OpenTelemetry-style)
- 🧵 Context management (`attach()`, `detach()`, `Scope`)
- 🕵️ Exception + status reporting
- 🐘 Works with **PHP 5.6**

---

📦 Installation
--------------

[](#-installation)

```
composer require sarigue/curlmetry
```

> Or just clone and `require 'vendor/autoload.php';`

---

🚀 Example: OTLP export
----------------------

[](#-example-otlp-export)

```
use Curlmetry\Tracer;
use Curlmetry\Exporter\OtlpExporter;
use Curlmetry\Processor\SimpleSpanProcessor;

$exporter = new OtlpExporter('http://localhost:4318/v1/traces');
$processor = new SimpleSpanProcessor($exporter, 'curlmetry-demo');
$tracer = new Tracer($processor);

$tracer->startActiveSpan('http.request', function ($span) {
    $span->setAttribute('http.method', 'GET');
    $span->addEvent('processing', ['step' => 'controller']);
    usleep(5000);
});
```

---

🌐 PSR-18 usage
--------------

[](#-psr-18-usage)

```
use Curlmetry\Psr\CurlHttpClient;
use Curlmetry\Psr\Request;

$client = new CurlHttpClient();

$request = new Request(
    'POST',
    'http://localhost:4318/v1/traces',
    ['Content-Type' => ['application/json']],
    json_encode(['resourceSpans' => [...]])
);

$response = $client->sendRequest($request);
echo $response->getStatusCode();
```
