PHP

Below is an example of making a HTTP request to SITE_NAME from PHP.

file_get_contents('PING_URL');

If you would like to setup timeout and retry options, as discussed in the reliability tips section, there is a curl package available that lets you do that easily:

use Curl\Curl;

$curl = new Curl();
$curl->setRetry(20);
$curl->setTimeout(5);
$curl->get('PING_URL');

Note: this code does not throw any exceptions.
