+If you'd like to setup timeout and retry options, as discussed in the [reliability tips section](../reliability_tips/), there is a [curl package](https://www.phpcurlclass.com/) available that lets you do that easily:
+
+```php
+use Curl\Curl;
+
+$curl = new Curl();
+$curl->setRetry(20);
+$curl->setTimeout(5);
+$curl->get('https://hc-ping.com/your-uuid-here');  
+```

+Note: this code never throws any exception.
