MysqlndUhConnection::getStatistics
(PECL mysqlnd-uh >= 1.0.0-alpha)
MysqlndUhConnection::getStatistics — Returns statistics about the client connection
说明
public MysqlndUhConnection::getStatistics ( mysqlnd_connection$connection
) : array
Returns statistics about the client connection.
Warning本函数还未编写文档,仅有参数列表。
参数
-
connection
-
Mysqlnd connection handle. Do not modify!
返回值
Connection statistics collected by mysqlnd.
范例
Example #1 MysqlndUhConnection::getStatistics() example
<?php
class proxy extends MysqlndUhConnection {
public function getStatistics($res) {
printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
$ret = parent::getStatistics($res);
printf("%s returns %s\n", __METHOD__, var_export($ret, true));
return $ret;
}
}
mysqlnd_uh_set_connection_proxy(new proxy());
$mysqli = new mysqli("localhost", "root", "", "test");
var_dump($mysqli->get_connection_stats());
?>
以上例程会输出:
proxy::getStatistics(array ( 0 => NULL, )) proxy::getStatistics returns array ( 'bytes_sent' => '73', 'bytes_received' => '77', 'packets_sent' => '2', 'packets_received' => '2', 'protocol_overhead_in'
