范例

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();
?>

以上例程的输出类似于：

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;
    }
  }
}
