(PECL solr >= 0.9.2)

说明
public SolrClient::ping(void): SolrPingResponse

参数
此函数没有参数。
返回值
Returns a SolrPingResponse object on success and throws an exception on failure.
错误/异常
Throws SolrClientException if the client had failed, or there was a connection issue.
Throws SolrServerException if the Solr Server had failed to satisfy the request.
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; } } }
