Example #1 SolrClient::ping() example
<?php
$options = array
(
'hostname' => SOLR_SERVER_HOSTNAME,
'login' => SOLR_SERVER_USERNAME,
'password' => SOLR_SERVER_PASSWORD,
'port' => SOLR_SERVER_PORT,
);
$client = new SolrClient($options);
$pingresponse = $client->ping();
?>Il precedente esempio visualizzerà qualcosa simile a:
class Search extends Solr
{
protected $searchEngine;
function __construct()
{
$this->searchEngine = $this->connect();
}
public function checkAlive()
{
$searchEngine = $this->searchEngine;
if($searchEngine->ping())
{
return true;
}
else
{
return false;
}
}
}
